LED Description
LINK
z
OFF means no link is present;
z ON means a link is present.
ACT
z OFF means no data is being transmitted or received;
z
Blinking means data is being received or/and transmitted.
Interface cable
The MIM-1POS uses LC fiber-optic connectors and must be connected using fiber-optic with an LC
connector.
Connecting the interface cable
Step1 Insert the SFP module into its corresponding slot.
Step2 Locate the Rx and Tx fiber-optic interfaces on the module. Use two fibers to connect the MIM-1POS to
another device, with Rx to Tx and Tx to Rx.
Step3 Check the LINK LED on the MIM-1POS panel: ON means the Rx link is present and OFF means the
opposite. Check the line in the second case.
Because invisible laser radiation may be emitted from the aperture of an optical port when no fiber is
connected or the dust cap is removed, do not stare into the open aperture.
Replace the dust cap when no fiber is connected to the optical port.

MIM-1CPOS
MIM-1CPOS(E)/MIM-1CPOS(T)
Introduction
MIM-1CPOS(E)/MIM-1CPOS(T) is short for the 1-port channelized SDH/SONET interface module. C
stands for channelized, and POS for Packet over SDH/SONET. MIM-1CPOS(E)/MIM-1CPOS(T)
provides one STM-1/OC3-compliant multi-channel interface and support communication speeds up to
155.52 Mbps.
MIM-1CPOS has two models: MIM-1CPOS(E) for E1 system and MIM-1CPOS(T) for T1 system.
MIM-1CPOS is inserted in a MIM slot of a modular router and communicates with the CPU through the
PCI interface to receive and transmit data on STM-1 channelized POS interface. It supports:
z
Four types of hot-swappable SFP optical interface modules for your choice: multi-mode short-haul
(1310 nm), single-mode medium-haul (1310 nm), single-mode long-haul (1310 nm), and
single-mode ultra-long-haul (1550 nm).
