1310nm O Band 3 ports Polarization Insensitive Mini Fiber Optic Circulator EPON
Description
Polarization insensitive optical circulator utilizes proprietary designs and metal bonding micro optics packaging. It provides low insertion loss, broad band high isolation, low PDL, excellent temperature stability and optical path epoxy free. It can be used for wavelength add/drop, dispersion compensation and EDFA application.The device used in optical communications systems, an optical circulator is built to pass light from one optical fiber to another. The movement occurs in the same direction the light is traveling, from the first port to the second, or the second to the third port. Most of these devices have three ports, and the incoming light beams can’t go back to other port, which means the device is non-reciprocal. These optical devices are used to pass light from a unidirectional to a duplex fiber communication link and also in optical testing instruments such as optical time-domain reflect meters.
Applications
Because of the optical circulators’ high isolation and low insertion loss, they are widely used in advanced communication systems as add-drop multiplexers, bi-directional pumping, and chromatic dispersion compensation devices.
The example to the under depicts the use of a circulator to drop an optical channel from a DWDM system using a fiber Bragg grating (FBG). The input DWDM channels are coupled into Port 1 of the device with a FBG device connected to Port 2. The single wavelength reflected off the FBG then reenters the circulator in port 2 and is routed accordingly to Port 3. The remaining signals pass through the FBG and exit on the top fiber.
Optical circulators can also be used to send optical signal in two directions down a single fiber. A circulator is located at both ends of the fiber. Each circulator functions to add a signal in one direction while removing the signal in the other. See the example below
