Product Description
Polarization Maintaining Components Fused Fiber Coupler For FTTx Solutions / CATV / FTTH
Product Overview
525nm, 630nm, 780nm, 850nm, 980nm 1x2, 2x2 Polarization Maintaining Fused Fiber Optic Coupler
1x2, 2x2 Polarization Maintaining Fused Fiber Optic Coupler uses unique fusing technique and polarization maintaining fiber to build the polarization maintaining fused standard coupler (PMC). The coupling ratio could be selected according to customer's request. It features low excess loss, small size and high polarization extinction ratio. PMC is widely used for optical sensors and optical gyro, optical amplifier.
Applications
- Fiber Amplifier
- Power Monitoring
- Fiber Optical Instrument
Features
- Low Insertion Loss
- High Return Loss
- High Extinction Ratio

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.
