Profile: Wuhan Yilut Technology Co., Ltd. specializes in the manufacture of optical passive components. Our products include planar light wave circuit splitters, fused biconical taper splitters, wavelength division multiplexers and patch cords. Our products can be widely used in CATV system, FTTH network, LAN system, and optical telecommunication system. PLC splitter is based on the planar waveguide Technology. It provides a low cost light distribution solution with small form factor and high reliability. The single mode optic-fiber tree and star couplers can couple the optical signals in the coupling area, and then re-distribute the light power. The key parameters include operating wavelength, bandwidth, excess loss, and coupling ratio. The multi mode fused fiber couplers are designed by cascade basic units to eliminate the module sensitivity. They can be widely used in LAN, PON, and optic-fiber sensors. Polarization insensitive optical circulator utilizes proprietary designs and metal bonding micro optics packaging. It provides low insertion loss, broad band high isolation, low PDL, excellent temperature stability, and optical path epoxy free. It can be used for wavelength add/drop, dispersion compensation and EDFA application.
