2. Overview: About the High-Density Media Converter System II Layer 2
Modules
The L2 is a Fast Ethernet module which provides a single conversion between
100BASE-TX twisted pair and 100BASE-FX/SX single-mode or multi-mode
fiber. Each L2 includes one RJ-45 connector and one pair of ST or SC fiber
optic connectors
Also available in a single-strand fiber version, L2 TX/SSFX allows two
wavelengths to share one fiber strand — Full-Duplex data travels on different
wavelengths, for example (1310 nm and 1550 nm) — doubling the capacity of
fiber.
The L2 is SNMP-manageable and can be installed into the modular, SNMP-
manageable High-Density Media Converter System II Layer 2 chassis, which is
unmanaged.
