To avoid excessive insertion loss as well as for longer link range and further expansion, 40CH DWDM MUX/DEMUXs are deployed in place of customer’s CWDM MUX/DEMUXs.
With the use of OEO, Ethernet signals are converted into corresponding wavelengths in DWDM transceivers.
For the safety of the whole link, link D and link E are designed as the backup lines of link C, thus site1 and site3 are separately deployed with two chassis in case of any failures, ensuring the network continuity.
Due to budget constraints, FS selects OADM at site2 to minimize the budget as much as possible. By deploying an OADM, wavelengths of link D or E are added or dropped to switch without interfering data transmission on link D and E.
Besides, EDFAs are used to compensate the cable losses in case that the fibre attenuation increases.
