Product Description
1x2 2x2 PM Fused Coupler 1030nm 1064nm 1310nm 1550nm 2000nm For Fiber Amplifier
Product Overview
New Arrival 1030nm, 1064nm, 1310nm, 1550nm, 2000nm 1x2, 2x2 PM Fused Coupler for Fiber Amplifier
As a component integrator, we can construct additional components directly onto the coupler fibers. Examples include tunable filters, variable attenuators, or collimators. Gezhi Photonics has the capability to connectorize the fibers of fused splitters with all standard connectors such as FC, SC, ST, LC etc. and finishes (Super PC, Ultra PC, Angled PC [APC] etc.). By building these devices directly onto the coupler fibers, we save the customer the added cost and insertion loss of intermediate connectors and adapters, or the time and cost of fusion splicing. Directly built devices are also the best way to maintain the highest possible Polarization Extinction Ratios.

Note:
1. The PM fused coupler is both axis working, no axis can be blocked; default test extinction ratio is on the slow axis.
Above specifications are for device without connector. If with connector, IL will be 0.3dB higher, return loss will be reduced 5dB and Extinction Ratio will reduce 2dB.
2. For >10W high power applications, we will use heat sink package.
3. If there is pulse application, please be sure to inform us of pulse energy and peak power.
