1x8 Polarization Maintaining Fused Coupler Module
980nm, 1064nm, 1310nm, 1550nm
GEZHI 1x8 FBT (fused biconical taper) PM fiber splitter support various wavelenth like 980nm, 1064nm, 1310nm, 1550nm or customzied wavelength. The coupling ratio also could be selected. It features low excess loss, small size and high polarization extinction ratio. The 1x8 Polarization Maintaining fused Splitter (PM splitter) is widely used for optical sensors, optical gyro and fiber optical instrument.

Note: 1. Above specifications are for device without connector, If with connector, IL will be 0.3dB higher, return loss with be reduce 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.
