Interface cables
Test optical power before choosing a transceiver module and optical fiber, because an optical fiber
connector might have transmitted for dozens of kilometers from a user fiber.
The HIM-RS2P supports the connection of Mate interfaces within the module. All Mate interfaces in a
module can be connected without external transceiver modules or fibers.
For the appearance and connection of a HIM-RS2P interface cable, see "

HIM-4G4P (RT-HIM-4G4P-H3)
The HIM-4G4P provides 4 Packet Over SDH/SONET (POS) interfaces and four 1000 Mbps Ethernet
fiber ports. A POS interface transmits data at STM-1/OC-3 (155.52Mbps). The HIM-4G4P is half the
height of a HIM, and occupies one slot on a FIP.
