In Release 6 and later releases, the FT-2000 OC-48 Add/Drop-Rings Terminal
may be equipped with the OC48 Transmitter, Add/Drop(A/D) — 1.5µmLBA
Wavelength 1 (OC48 TRMTR [A/D 1.5 LBA W1]) and the OC48 Transmitter,
Add/Drop(A/D) — 1.5µm LBA Wavelength 2 (OC48 TRMTR [A/D 1.5 LBA W2])
circuit packs in WDM applications. In Release 7 and later releases, the FT-2000
OC-48 Add/Drop-Rings Terminal may be equipped with the OC48 TRMTR (A/D
STS1 1.5 LBA, W1) and the OC48 TRMTR (A/D STS1 1.5 LBA, W2) circuit packs
in WDM applications. The 7A WDM Filter Assembly is recommended for use with
these OC48 TRMTR circuit packs.
