Cisco SFP-OC3-LR2

The Cisco SFP-OC3-LR2 is a Small Form-Factor Pluggable (SFP) transceiver module designed for use in optical communication networks. It is specifically designed for OC-3/STM-1 (Optical Carrier level 3/Synchronous Transport Module level 1) applications, which provide a data transfer rate of 155.52 Mbps. The "LR2" in the product name stands for "Long Reach 2," indicating that this SFP module is capable of transmitting data over longer distances compared to other SFP modules. It supports a maximum link length of up to 40 kilometers (24.85 miles) over single-mode fiber. The Cisco SFP-OC3-LR2 is hot-swappable, meaning it can be inserted or removed from a compatible networking device without powering down the system. It is commonly used in Cisco networking equipment, such as routers and switches, to provide high-speed and long-distance optical connectivity.
