The Ethernet fiber ports of the HIM-4G4P support 1000 Mbps SFP fiber transceiver modules 1000 Mbps
SFP copper transceiver modules, and the POS interfaces support 155 Mbps SFP fiber transceiver
modules.
The transceiver modules are optional.
Interface cables
The HIM-4G4P is used together with SFP transceiver modules and fibers with LC connectors.
For the appearance and connection of a HIM-4G4P interface cable, see "
HIM-TS8P (RT-HIM-TS8P-H3)
The HIM-TS8P provides 8 ports, each of which can be switched between a POS interface and an Ethernet
port. A POS interface transmits data at OC-3/STM-1 (155.52Mbps) or OC-12/STM-4 (622Mbps). An
