NM-1A-OC3SMI-EP Cisco ATM OC-3 Single-Mode Network Module, Enhanced Performance
- Description
- Specifications
The NM-1A-OC3SMI-EP is the enhanced-performance form of the Cisco ATM OC-3 single-mode intermediate-reach (SMI) network module, supported in the Cisco 3745 router. Its single fiber uplink port carries ATM at the 155-Mbps OC-3/STM-1 rate.
Five LEDs sit on the faceplate. EN is green when the module has passed its self-tests and is available to the router, and RCLK is green when a receive clock is detected. FERF, OOF and AIS are yellow and mark far-end receive failure, out of frame and alarm indication signal.
Connect the network fiber with an SC connector, duplex or as two simplex plugs. The port uses a small laser: keep the transmit port covered when no cable is attached. Related adapters and modules are in the Cisco interface card category.
