Varizble Optical Attenuators (VOA) With Epoxy-free Optical Path have low insertion loss, High return loss and Low PDL. They can be used for power control and equalization for WDMs, FTTx, CATV and Test & Measurement instruments. These will be a powerful solution for the market demand of cost-effective system. Optical isolators can block back flections and backscattering in the reverse direction at any polarization sate. They have low polarization mode dispersion (PMD). The optical path is epoxy-free, thereby enabling high-power applications. They are based on the micro-optics package technology and featured with the best stability and reliability. ***4,C-band,L-band, Dual Stage are also available. Optical circulator is marked with an ultra compact package and high stability. It is an ideal candidate for EDFA, add/drop, dispersion compensation and bi-direction transmission xxxxx 3 port ,4 port ,***0,***0,***0 are all available. Optical Fiber Patch cords is the cable with a connector installed on its each end respectively to make the jumping connection of light path. PM Patch cord is the cable with a connectors attached on its two end respectively to realize the jumping connection of light path.**0,***0,***0,***0nm are all available. The polarization maintaining (PM) coupler is a compact low loss micro-optic filter type inline coupler (1x2) which provides PM optical signal splitting (various splitting ratios available) over a wide bandwidth while preserving the polarization with high extinction ratio. The polarization maintaining fiber isolator eliminates back reflection and back scattering of optical signals in the transmitted polarization and maintains the polarization of the light at high extinction ratio. This single stage isolator features high isolation, very low insertion loss, high extinction ratio, high return loss, and very high thermal stability in a compact design. PM Circulator,WDM are also available.
