Figure 2-19 shows how the WDM filters multiplex and demultiplex two

single-mode 1.5 µm wavelength signals with slightly different wavelengths. Thus,

two FT-2000 OC-48 Lightwave Systems at the same location, each equipped for

lightwave transmission at different wavelengths, can share the same fiber pair.

(1.5 µm/1.5 µm)

In Release 6 and later releases, the FT-2000 OC-48 Repeater Bay may be

equipped with the OC48 REGENR — 1.5µm Standard Performance (OC48

REGENR [1.5 LBA W1]) and the OC48 Regenerator — 1.5 µm Standard

Performance (OC48 REGENR [1.5 LBA W2]) circuit packs when using

wavelength division multiplexing. The OC48 REGENR (1.5 LBA W1) circuit pack

operates at the same wavelengths as the OC48 TRMTR (A/D 1.5 LBA W1) and

OC48 TRMTR (A/D STS1 1.5 LBA, W1) circuit packs. The OC48 REGENR (1.5

LBA W2) circuit pack operates at the same wavelengths as the OC48 TRMTR

(A/D 1.5 LBA W2) and OC48 TRMTR (A/D STS1 1.5 LBA, W2) circuit packs.
