4. FAQ

Q1: Which wavelength channels are included in the 19CH O+C-Band DWDM Module?

The module integrates 8 O-band channels and 11 C-band channels.

The O-band channels are:

O284, O286, O288, O290, O292, O294, O296, O298

with center wavelengths from 1312.58 nm to 1304.58 nm and 200 GHz channel spacing.

The C-band channels are:

C20, C21, C22, C23, C24, C25, C26, C27, C28, C29, C30

with center wavelengths from 1561.42 nm to 1553.33 nm and 100 GHz channel spacing.

Q2: What is the advantage of integrating O-band and C-band channels in one module?

Integrating O-band and C-band wavelength channels into one passive module allows two widely separated optical wavelength regions to be routed through a common optical component. This can simplify multi-band optical system architecture and reduce the number of separate wavelength-management components required in systems that use both wavelength bands.

The supplied specification also states compliance with Telcordia GR-1209 / GR-1221 reliability requirements and RoHS 2.0.
