Things That You Must Know about Polarization Maintaining Optical Circulator

---

Optical fiber is used for an electric
device in which light polarization is required. And each fiber is designed to
do a certain job and so is suitable for some certain applications. So you
should have the knowledge of an optical fiber that you want to buy and make
sure the fiber you want to buy would be perfect for your need. So we have
gathered some crucial information about optical circulator used for maintaining
light polarization, and that will help you choose the right fiber.

 

If you are looking for a circulator for
devices like fiber amplifiers, fiber sensors, test and measurement appliances,
coherent detecting appliances, the 1310nm&1550nm 3-port Polarization
Maintaining Optical Circulator with both axis working would be the best
choice. The circulator is compact and very efficient to route the incoming
signals from Port 1 to Port 2, and incoming Port 2 signals to Port 3. The
circulator works as a single that can be used to transmit light from an input
fiber to an output fiber. It directs the light returning from the output fiber
to the third port. The 3 port circulator with both axis working is like an
isolator that protects the input fiber from return power but the light that is
rejected can be used.

 

Another fiber can be also used for those
applications is 3 port optic circulator with fast axis blocked. This type of
circulator is also lightweight, compact and performs well. This circulator also
works as the circulator (with both axis working) does. Both circulators used
for maintaining polarization can handle the power ranging from 300mW to 20 W,
and have center operating wavelengths ranging from 850nm to 1650nm.

 

Both optical circulators (with both axis
working and with fast axis blocked) provide a host of benefits such as low
insertion loss, high isolations, etc. Here are some key benefits that the
circulator provides:

 

Low Insertion Loss

High Isolation

High Extinction Ratio

Low Cost

High Stability & Reliability

Apart from those two circulators that are
widely used for a wide range of applications, there are other optical fibers
that are used for electric devices. Whatever fiber you buy make sure it works
perfectly with your device.

 

So before you start looking for optical
fibers, get to know about your device in details. Learn everything that can
help you in a way or so to decide on which type of optic fiber you should look
for.

 

Once you are done with the type of fiber
you need, find a Polarization Maintaining Optical Circulator supplier. There
are many Polarization Maintaining Optical Circulator suppliers in China, you
should trust only those that are reputed and have long been into the business.
