After the channels leave the last 32WSS-L card or 40-WSS-CE card, the C-band even and odd
channels are interleaved back into a single stream by the ONS 15216-ID-50 module, sent through a
booster amplifier, and then they enter the ONS 15216-SC-CL module, where they are combined with
the L-band signals from the lower set of blocks and sent out onto the optical fiber.
