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.
