The Cisco SFP-OC3-IR1 OC-3/STM-1 SFP Transceiver is a compact optical module designed for SONET and SDH network applications requiring reliable data transmission over single-mode fiber. Built in the Small Form-Factor Pluggable (SFP) format, this transceiver supports the OC-3 / STM-1 communication standard, delivering stable optical connectivity for telecommunications infrastructure, enterprise networks, and service provider environments.Operating at a nominal wavelength of 1310 nm, the SFP-OC3-IR1 module provides Intermediate Reach (IR) optical performance and supports transmission distances of up to 15 kilometers over standard single-mode fiber (SMF). The module enables a data rate of 155 Mbps, making it suitable for SONET/SDH transport systems and legacy optical communication networks that require dependable medium-distance connectivity.
The transceiver features a duplex LC optical connector, ensuring compatibility with widely used fiber optic patch cables and network infrastructure. It supports hot-swappable installation, allowing administrators to insert or replace the module without powering down the host device. This capability simplifies network maintenance and reduces operational downtime.
The Cisco SFP-OC3-IR1 module is designed to provide stable optical output, reliable signal integrity, and efficient performance in SONET/SDH networking equipment such as routers, switches, and multiplexers. Its compact SFP design allows for high port density and flexible deployment in modern network environments.
