Though there are 2 pairs of fibre links at present, more channels for traffic transmission are potentially needed in the future.
For the fact that the total loss across the optical path should be less than 28dB but the whole link loss for the 60 km link is nearly 24dB and the client has already got 1+1 OLP, how many amplifiers are needed and where the amplifier should be placed become issues.
In addition, our client requires extra instruments for optical monitoring.
FS OTN technical team proposes a point to point model for the 100G DWDM design.

To ensure normal running of the two traffic channels and the potentially more channels in the future, two 16CH DWDM MUX/DEMUXs are deployed, which are possible to support up to 16×100G traffic transmission.
Owing to the distance limitation of QSFP28 modules, 100G transponders are used to convert QSFP28 to 100G coherent CFP so as to realize 100G data transmission over a longer distance.
In each link, a booster amplifier (BA) is installed behind the DWDM MUX/DEMUX and the pre-amplifier (PA) is placed before the DWDM MUX/DEMUX with the consideration of the link loss and insertion loss of OLP.
To keep the transceiver modules working properly with the output power of 100G DWDM modules limited in a range from -3dBm to -15dBm, some optical attenuators are equipped.
With the aim of monitoring two fibre bidirectional links, a customised OTDR and 1×4 OSW optical switches are used so that client can manually switch or automatically monitor optical paths.
