Information
The Cisco 16CHOC3/DS3-IR-LC is a line card module designed for use in Cisco Catalyst 6500 Series switches. It provides 16 ports for connecting optical carrier level 3 (OC3) or DS3 (Digital Signal Level 3) circuits. The "IR" in the name stands for intermediate reach, indicating that it supports transmission distances of up to 40 kilometers. The "LC" refers to the type of optical connector used, which is the LC (Lucent Connector) type. This line card is typically used in telecommunications and service provider networks to connect and transport high-speed data over long distances.
