Optical (ATM) Line Card Interfaces
The OLC2 has four optical fiber interfaces (ports) that support IP or Broadband-SS7 over ATM (Asynchronous Transfer
Mode). These ports connect our SGSN products via IuPS interfaces to other elements in the packet data network.
The type of optical fiber interface on the line card is dictated by the Small Form-factor Pluggable (SFP) transceiver
modules installed on the line card. The OLC2 supports two versions of SFP modules. SFP modules are hot-pluggable.

Important: The SFP interface is only certified to work with SFP transceiver modules purchased from Cisco for
use with the OLC2.
Important: Because of the optical SFP interface, this product has been tested and found to comply with the
limits for Class 1 laser devices for IEC825, EN60825, and 21CFR1040 specifications.
The following figure shows the optical interface, labelled ATM/POS OC-3, for the optical (ATM) line card. Each SFP
fiber interface is equipped with a transmit (TX) port and a receive (RX) port.
