Interface cables
The HIM-CL1P/HIM-CL2P must work with an SFP transceiver module and an optical fiber that have
LC-type connectors. For the appearance and connection of a HIM-CL1P/HIM-CL2P interface cable, see

Connecting an optical interface cable
HIM-CLS1P (RT-HIM-CLS1P-H3)/HIM-CLS2P
(RT-HIM-CLS2P-H3)
The HIM-CLS1P and HIM-CLS2P are high-speed OC-3/STM-1 (155 Mbps) CPOS E3/T3 interface
modules. They can also operate in packet over SONET/SDH (POS) mode. The HIM-CLS1P provides one
SFP port and the port is provided with two LEDs, which indicate the port running status and fault detection
status, respectively. The HIM-CLS2P provides two SFP ports.
The HIM-CLS1P/HIM-CLS2P has the following features:
•
Connects to the processor through a 10-Gbps high-speed bus. Each OC-3/STM-1 POS interface
can be channelized into three E3s or T3s.
•
Each E3/T3 channel supports the subrate processing capability, providing users with a variety of
bandwidth options.
•
Receives multiplexed E3/T3 circuits on a pair of fibers through a channelized interface, saving
many link resources, the occupied area, and the cost of local networks and devices for
telecommunication service providers and large enterprises.
•
Supports IP and MPLS traffic and MP with up to three E3s or T3s in each MP bundle.
