7.1 Optical Interfaces
The following tables define the specifications for each optical PLM (Physical Layer Module)
available for the TE-2020. The optics are defined by their ability to transmit over distances as
Short Reach (SR), Intermediate Reach (IR), and Long Reach (LR), and by the Laser type as Multi-
Longitudinal Mode (MLM) and Single-Longitudinal Mode (SLM).
Caution! Care should be taken when inserting optical fibers into the optical PLMs.
Ensure that optical power level input levels do not exceed the maximum input
levels specified for the PLM (See the TE-2020 Applications Engineering Guide
(WR-D2020-APP-050000) for details). Input optical measurements must be taken
and attenuation adjustments must be
made before inserting the fibers, other-
wise permanent damage could occur to the optical receivers. Damaged
optical receivers due to application of power levels in excess of those
defined in Turin Networks's specifications are not covered by Turin Net-
works' product warranty.
7.1.1 OC-3 PLMs
The OC-3 PLM provides up to four ports (quad OC-3 PLM) that may be utilized simultaneously.
Refer to Table 7-1 for OC-3 PLM specifications.
