Polarization Maintaining Fused Coupler (1x2,2x2)
525nm, 630nm, 780nm, 850nm, 980nm
GEZHI 1x2 or 2x2 PM Fused couplers are ideal components to split or combine light signals between two fibers over a wide wavelength and temperature range. Its used PANDA fiber which with both axis working only. It features low excess loss, small size and high polarization extinction ratio. And widely used in fiber amplifier, power monitoring 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.
