The 9-Degree ROADM card (WSS) launched by D Tech Trading supports the integration of key functions WSS, BA, PA and OSC into one card, has built-in dual 1x9 WSS components and has 9 ports for wavelength multiplexing and demultiplexing. It supports a DWDM Network with 96 channels (50GHz wavelength interval) in the frequency range of 191.35THz ~ 196.10THz in the C-band. It also supports the flexible grid function, realizes the flexible adjustment of channel bandwidth, and improves the spectrum utilization of the whole network.

Application case:

Suitable for dynamic add/drop and pass-through of optical wavelength in OADM station
Suitable for dynamic pass-through and scheduling of multi-degree optical wavelengths in ROADM station
