980/1550nm  WDM  Module  can  combine  980nm  and  1550nm signals  into  one  fiber  or  separate  980nm and  1550nm   signals into  two  fiber. The product is widely used for amplifier and WDM systems.

850/1310+1550 WDMs are based on thin film filter technology.The products adopt hermetic package craft and environmental stability.  They can be used in high-power applications in WDM systems.

1310/1550nm WDM is based on thin film filter technology.The products adopt hermetic package craft and environmental stability.  It can be used in high-power applications in WDM systems.The products are Telcordia GR-1221-CORE qualified and RoHS compliant.

1310+1550/1490nm WDM are based on thin film filter technology. The products adopt hermetic package craft and environmental stability. The main applications of this group of WDM are FTTH network.The products are Telcordia GR-1221-CORE qualified and RoHS compliant.

1310+1490/1550nm or 1550/1310+1490nm WDM are based on thin film filter technology. The main applications of this group of WDM are FTTH network. The products adopt hermetic package craft and environmental stability.

100GHz, 200GHz 3-port TFF devices and multi-channel modules are available on ITU channel spacing of 100GHz,200GHz spacing. These thin film filter  products utilize hermetic and epoxy-free  optical  path technology to provide excellent performance and reliability.

Optical add/drop Multiplexer are available on ITU channel spacing of 100GHz and 200GHz, they are based on thin film filter technology and flexible integration of taps and detectors for a complete dense wavelength division multiplexing solution.

Multi-channel mux/demux  modules are available on 8-channel and 16-channel with reflective wavelength of C band or all band. These devices can be designed to satisfy any customer-specify channel plan,and integration of taps and detectors for a complete CWDM solution.

Compact CWDMs are based on thin film filter technology and free space package technology,used to multiplex or de-multiplex 4 channel or 8 channel CWDM wavelength in the range of 1271~1611nm, and  P grade port is optional。

Standard WDM/Isolator Hybrid could replace 1pc thin film WDM+1pc Isolator, which is the ideal component for compact amplifier, with its compact size and competitive price.
