Interface cables
The HIM-PS1P must work with an SFP transceiver module and an optical fiber with LC-type connectors.
For the appearance and connection of a HIM-PS1P interface cable, see "
Connecting an optical interface
HIM-AL1P (RT-HIM-AL1P-H3)/HIM-AL2P (RT-HIM-AL2P-H3)
The HIM-AL1P and HIM-AL2P are OC-3/STM-1 (155 Mbps) Asynchronous Transfer Mode (ATM)
interface modules. The HIM-AL1P provides an SFP port and the port is provided with two LEDs, which
indicate the interface running status and fault detection status, respectively. The HIM-AL2P provides two
SFP ports.
The HIM-AL1P/HIM-AL2P has the following features:
•
Supports frame formats of SDH STM-1 and SONET OC-3C.
•
Allows data scrambling transmission.
•
Supports line clock mode and internal clock mode.
•
Provides self loopback testing measures such as internal cell loopback, external SONET/SDH
loopback, and remote loopback.
•
Supports hot swapping.
