M-M: multi-mode S-M: single-mode [All optical transceivers are rated Class A.]
* WDM types must match (A) with (B) in pairs
** Bit Error Rate
All fiber transceivers in the Multiplexer incorporate an automatic laser shutdown feature
(ALS) designed to protect personnel that may come into contact with a disconnected fiber
connection. This feature may also be disabled for testing purposes via the front panel LCD, console
terminal mode or SNMP (when SNMP option is installed). The fiber module ports may be
independently installed with any of the above fiber features and must only match the remote side's
module. Fiber modules are completely hot swappable and may be replaced in the field without
taking the unit out of service.
