7.1.3 OC-48 PLMs
The current OC-48 PLM offerings include a single-, two-, and four-port versions. There is an IR-1
reach PLM and five types of long reach (LR-1, LR-2, VR-1, and ITU) modules that may be uti-
lized according to wavelength and power desired. Refer to Table 7-3 and Table 7-4 for OC-48
PLM specifications.
