PLC TYPE WDM

Instead of taking a thin film filter to mux or demux wavelengths, PLC type achieves the same goal by using chip PLC, 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.

PLC-type WDM products are a type of product developed based on planar optical waveguide technology, which uses the principle of arrayed waveguide grating to realize the function of wave division and multiplexing; currently this type of product is mainly divided into two categories, the first category is high-channel 100G DWDM product AWG; the second type is low-channel CWDM or Lan-WDM, the first type is mainly used in high-density long-distance metro DWDM transmission network, and cooperates with EDFA to realize long-distance high-capacity backbone fiber transmission; the second type Mainly used in TOSA and ROSA of various QSFP optical modules to realize 4*10G/4*25G parallel high-speed transmission.
