Fiber Optic Connectors - The Complete Guide
The network cabling industry's fiber optic manufacturers over the last few
decades have been on a constant mission to develop the better fiber connector.
This means lower cost, lower dB losses, easier to terminate out in the field.
There have been over 100 connectors developed over the years but a select few
have stood the test of time and beat out their competition. Below we will talk
about the most common.
A fiber optic connector terminates at the end of a fiber optic cable and is
used when you need a means to connect and disconnect the fiber cable quickly. A
fiber splice would be used in a more permanent application. The connectors
provide a mechanical connection for the two fiber cables and align both cores
precisely so the light can pass through with little loss. There are many
different types of connectors but many share similar characteristics. Many
connectors are spring loaded. This will push the fiber ends very close to each
other so as to eliminate airspace between them, which would result in higher dB
losses.
There are generally five main components to a fiber connector: the ferrule,
the body, the coupling structure, the boot and the dust cap.
Ferrule-the ferrule is the small round cylinder that actually makes contact
with the glass and holds it in place. These are commonly made of ceramic today
but also are made of metal and plastic.
Body-This sub assembly holds the ferrule in place. It then fits into the
connector housing.
Connector Housing-This holds all sub assembly parts in place and has the
coupling that will connect to the customer's equipment. The securing mechanism
is usually bayonet, snap-in or a screw on type.
Boot-This will cover the transition from the connector to the fiber optic
cable. Provides stress relief.
Dust Cap-Just as it implies will protect the connector from accumulating
dust.
There are many types of connectors on the market. The major differences are
the dimensions and the method of connection to equipment. Most companies will
settle on one type of connector and keep that as a standard across the board.
It makes sense because all equipment has to be ordered with that specific
connector type and to have 2 or 3 different connector types can get messy. For
typical network cabling projects today LC is fast becoming the shining star of
fiber connectors. LC is a small form factor connector which means it requires a
much smaller footprint in your IT closet. Thus you can fit many more LC
connectors into you fiber panels then say ST or SC connectors.
ST Connector
The ST connector (or Straight Tip) was the first popular connector type to
be used as a standard for many organizations in their fiber network
applications. It was first developed by AT&T. Often called the "round
connector" it has a spring loaded twist bayonet mount with a 2.5mm round
ferrule and a round body. The ST connector is fast being replaced with the
smaller, denser SFF connectors.
SC Connector
The SC connector is a push-in/pull-out type connector that also has a 2.5
mm ferrule. It is very popular for its excellent performance record. The SC
connector was standardized in TIA-568-A, and has been very popular for the last
15 years or so. It took a while to surpass the ST because of price and the fact
that users were comfortable with the ST. Now it's much more competitive with
pricing and it is a very easy install, only requiring a push in and pull out
connection. This is very helpful in tight spaces. Simplex and duplex SC
connectors are available. The SC was developed by the Japanese and some say
stands for Standard Connector.
FDDI/ ESCON Connectors
You may see FDDI and ESCON(IBM) duplex fiber connectors in older
installations. These connectors will mate to their own networks and usually
will be seen at the wall outlet locations. These connectors use a squeeze tab
coupling mechanism. The closet side of the fiber will usually have a standard
ST or SC connector. The FDDI/ESCON connectors can be mated to SC or ST
connectors since they both have a 2.5mm ferrule. An adaptor would be required
in this case. The FDDI stands for Fiber Distributed Data Interface.
LC Connector
The LC connector was developed by Lucent Technologies, hence the LC. It is
a Single Form Factor Connector that has a 1.25mm ferrule. The attaching
mechanism is similar to an RJ-45 connector with the retaining clip. It is a
smaller square connector, similar to the SC. LC connectors are often held
together with a duplex plastic retainer. They are also very common in single
mode fiber applications.
MT-RJ Connector
MTRJ stands for Mechanical-Transfer Registered Jack and was developed by
Amp/Tyco and Corning. MTRJ is very similar to an RJ type modular plug. The
connector is always found in duplex form. The body assembly of the connector is
usually made from plastic and clips and locks into place. There are small pins
present that guide the fiber for correct alignment. MTRJ's also are available
in male or female orientation. They are only used for multi-mode applications.
They can also be difficult to test because many testers on the market do not
accept a direct connection. You usually need to rig up a patch cord adaptor kit
to make testing possible.
FC Connector
The FC connector you may find in older single mode installations. It was a
popular choice that has been replaced by mostly ST or SC type connectors. It
also has a 2.5mm ferrule. They have a screw on retaining mechanism but you need
to be sure the key and slot on the connector are aligned correctly. FC
connectors can also be mated to ST & SC's through the use of an adaptor.
Panduit Opti-Jack Connector
The Panduit Opti-Jack is a clean, tough duplex connector cleverly designed
around two ST-type ferrules in a package the size of a RJ-45. It has male and
female (plug and jack) versions.
Volition Connector
3M's Volition is a slick, inexpensive duplex connector that uses no ferrule
at all. It aligns fibers in a V-groove like a splice. Plug and jack versions,
but field terminate jacks only.
LX-5 Connector
LX-5 is like a LC but with a shutter over the end of the fiber.
MU Connector
MU looks a miniature SC with a 1.25 mm ferrule. It's more popular in Japan.
MT Connector
MT is a 12 fiber connector for ribbon cable. It's main use is for
preterminated cable assemblies and cabling systems. Here is a 12 fiber MT
broken out into 12 STs.
This connector is sometimes called a MTP or MPO which are commercial names.
Hopefully this guide may help you get an idea of what options are out there
for your fiber optic connector needs.

Prevent the Need for Air Conditioning Service With Preventive Maintenance
Warmer weather is right around the corner, and many homeowners are making
their spring "to-do" list. As you make your list this year, the top
item should be scheduling preventive maintenance on your air conditioner. A
yearly tuneup of your system will extend its life and ensure it works
efficiently to keep you cool all summer long, lowering your utility bill and
preventing the need for air conditioning service in the heat of the summer.
A comprehensive tuneup by a qualified HVAC technician will include these
key points:
·
Lubricate the system's moving parts to prevent friction.
·
Check the system's controls to make sure your air conditioner cycles
properly.
·
Record the operating temperatures and pressures.
·
Inspect the relays and capacitors for damage.
·
Check the refrigerant level and test for leaks.
·
Flush the condensate drain to ensure it drains properly.
·
Tighten the electrical connections.
·
Inspect the blower motor and belts for wear.
·
Clean and adjust the thermostat to ensure accuracy.
·
Check the voltage and amperage on the motor.
·
Clean the compressor contacts.
·
Clean the outdoor condensing unit.
Preventive air conditioning service doesn't end with the annual tuneup.
There are several things you can do over the course of the cooling season to
keep your system operating at its peak performance:
·
Check your air conditioner's air filter every month and replace it when
it's dirty. Your air filter is your first defense against dust buildup in your
system, which makes it work harder to keep you comfortable and can cause
overheating and expensive related damage. Choose a quality air filter with a
MERV rating of at least 5 to remove more and smaller particles from your air.
·
Keep obstructions away from your outdoor condensing unit. Grass clippings
can adhere to the unit and reduce the flow of air to your system. Remove plant
growth around your unit and hose it down monthly to remove dust buildup, which
can reduce its efficiency.
·
Maintain the area around your indoor unit. Keep it free of dust, which can
build up inside the system. Remove stored items that may be an obstacle in the
event air conditioning service is needed.
·
Make sure your supply and return registers aren't blocked by drapes or
furniture, which can impede airflow to your system and cause overheating and
related damage. Never close off more than 20 percent of your registers in an
attempt to save on energy costs. Doing so will backfire due to reduced air
flow, and will make your system work harder to keep your home cool.
Troubleshooting common air conditioning problems can save you money on air
conditioning service. If your air conditioner isn't turning on at all, check
the fuses associated with your system. If it's not cooling effectively, try
changing the air filter, make sure the outdoor unit is clean and check for
obstructions around the return and supply registers. If service is needed,
choose a NATE-certified technician to perform the work. The North American
Technician Excellence, a nonprofit certification organization, provides
rigorous testing to ensure your HVAC professional is highly skilled and
knowledgeable about HVAC systems, resulting in excellent service and fewer
callbacks.

Save Time When You Use Older Versions of Microsoft Office
No matter how long you have been using Microsoft Word 2003 for, these
simple tips are sure to help you save considerable amounts of time.
Change Personalized Toolbar and Menu
Setting:
Change the default setting which keep you from seeing all the menu commands
and toolbar buttons. Usually, one has only a single row of commands and it
takes a few seconds for the other commands to expand after being clicked.
Follow these steps to avoid this inconvenience:
1. Go to Tools >
Customize and select the options tab.
2. In Personalized Menus and
Toolbars, click on "Show Formatting and Standard Toolbars on two
rows" and "Always show full menus." Please remember that the
descriptions relating to these options will be different in Word 2000.
3. You will be able to
see the entire menu when you close.
Discontinue automatic text changes:
Autocorrect is responsible for Word changing the spellings or cases while
you type. It not only corrects the spellings of words but also capitalizes the
first letter of a sentence. To alter these settings, go to Tools >
AutoCorrect Options and uncheck the options which you do not wish to see from
the AutoCorrect tab.
Cancel Automatic numbered Lists
It is highly problematic for someone to create a custom layout while
working with Word as both the numbering as well as the formatting change as
soon as you type enter. Also, an email address or a website immediately gets
hyperlinked and fractions get reformatted. These AutoFormat settings can be
changed in the following manner:
1. Go to Tools and select
AutoCorrect options.
2. Select AutoFormat and
unselect the last sections comprising of the numbered list option.
3. Click OK to save
settings.
Change your default font:
If you find yourself wasting time in changing the font every time, go ahead
and alter the default font like this:
1. Start a new Word file.
2. Click on Format >
Font and change the font and size as per your preference.
3. Click on default
instead of OK for the changes to be applicable even after you close the current
document.
4. There will be a prompt
confirming if you want the default font to be changed. Click on Yes.
Suit Page Layout and Margins to your
needs:
The custom margin setting for Word has been constant since Word 1.0. in
order to save time wasted in changing margins every time, one can:
1. Open a new Word file.
2. Go to File > Page
Setup and click on Margins tab.
3. Change the margins as
per specific requirements.
4. Make any other
necessary changes like Paper source or custom footer.

Facebook Introduces the "Home" for Android
After a few days made a curious, Facebook finally launched
the "new house" named Facebook Home Thursday (4/4/2013) at 1 pm
Eastern United States time.
"We cannot build a cell phone, and we could not develop
its own operating system," said Facebook founder Mark Zuckerberg on stage,
as reported by Engadget. And if Facebook Home?
Facebook's true Home is an application that is a little
different than other smartphone applications because it runs on an operating
system but be under other applications, such as the elaboration in the image
below.
Platform choice falls to the Google Android operating system
hosts. The reason is called Zuckerberg not far from the "open" nature
of the open-source OS.
So run, Facebook Home will change the Lockscreen and
Homescreen Android with a new look called the Feed Cover.
As the name suggests, Cover the Feed presents an update of
the latest news feeds of Facebook users in the form of drawings or photographs
that meet the screen, also a bit of affidavits regarding the feed in question.
All of these feeds to be updated automatically in the
background. Users need not open Facebook applications or even opening the lock
cell phones to follow the latest development of social life.
A feed can respond directly-for example to write comments by
doing double tapping.
What if users want to access another application in the
Android smartphone hers? Simply apply it with fingers of a user photo in the
bottom Cover Feed, and all applications can be accessed from the launcher
Android as usual.
Well, as long as the user opens a folder application,
Facebook Home (by tamilan Cover Feed) will continue to run in the background,
as can be seen in the image below.
If there are friends who send messages on Facebook Chat
users, then the notification form friends photos will be displayed at the top
of the screen, even when the user is in another application.
The user could then direct respond by touching pictures of
friends and opens the chat interface. This feature is called "Chat
Heads".
Facebook Home will begin on April 12, available through
Google's upcoming Play Store. Unfortunately, this application can only be used
in certain types of smartphones, the HTC One X, One X + HTC, Samsung Galaxy,
Samsung Galaxy SIII Note.
Support for other smartphones such as HTC Galaxy S4
following One and tablet device will be added in the future. As for Android
device manufacturers who are already partnering with Facebook to provide Home
is the HTC, Samsung, and Sony.
