T&S is an expert in manufacturing Wavelength Division Multiplexing (WDM). Our WDM fiber optic products are relied upon by some of the large scale telecom projects worldwide.
We have been providing WDM multiplexers for nearly two decades. With deep understanding and technical know-how of WDM, our in-house team of experts are able to advise our customers and keep T&S products being finely tuned to market requirements up to date.
T&S TFF WDM is based on Thin Film Filter (TFF) technology. Our Filter-Based WDM product family covers following wavelength windows commonly used in optical fiber systems: 1310/1490/1550nm (for FWDM Device), 1271~1611nm (for CWDM Device or Module). 1525~1565nm (C_band for 100G/200G DWDM Device or Module) and 1269.23~1318.35nm (for 800G LWDM Device or Module), 1271±3.5~1371±3.5nm (for MWDM Device or Module) and 1270/1310/1490/1534/1577/1610/1650nm (for Cex-wdm Modules, including GPON, XG-PON, NG-PON2 and OTDR )
We provide a wide range of solutions for wavelength management applications. With wide channel bandwidth, low insertion loss, high channel isolation, high environmentally stability and reliability, T&S WDMs are largely used in amplifiers, CATV, PON, network monitoring or expansion. Custom configurations are available upon request.
Instead of taking a thin film filter to mux or demux wavelengths, PLC type achieves the same goal by using PLC chip, which uniformly divides and guides light with different wavelengths. At T&S, we currently provide multi-channel AWG DWDM Modules and 4ch CWDM/LWDM Devices.
1525~1565nm (C_band for 100G multi-channel AWG Module) and 1271~1331nm&1295.56~1309.14nm(for PLC CWDM4&LWDM4 devices, They are used for 4x10 Gbps CWDM TOSA&ROSA for QSFP+ or 4X25 Gbps LAN-WDM TOSA&ROSA for QSFP+.
