3x3 Polarization Maintaining Fused Coupler
780nm, 980nm, 1030nm, 1064nm, 1310nm, 1550nm
GEZHI 3x3 monolithic FBT (fused biconical taper) PM fiber splitter support various wavelenth from 780nm~1550nm or customzied wavelength. The coupling ratio also could be selected. It features low excess loss, small size and high polarization extinction ratio. The 3x3 Polarization Maintaining fused Splitter (PM splitter) is widely used for optical sensors, optical gyro and fiber optical instrument.

Note: 1. the PM fused coupler is both axis working, no axis can be blocked; default test extinction ratio is on the slow axis.
2. 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.
3. For >10W high power applications, we will use heat sink package
4. If there is pulse application, please be sure to inform us of pulse energy and peak power.
