Welcome to Xuzhou Xuhai Opto-Electronic Technologies Co., Ltd.

OTDR&Same Wavelength BIDI Transmission

   Xuhai’s free space circulator shows obvious advantage compared with general solution in application of same wavelength BIDI TRV and SFP OTDR.Xuhai Free space circulator can achieve small dimension of 2mmx2.5mmx3.5mm,Excellent optical performance and reliable quality using our unique design and material.

Xuhai’s free space circulator can realize optics circulation which make same wavelength BIDI and SFP OTDR easy to realize.
