Cisco SFP-OC3-IR1 Module
The Cisco SFP-OC3-IR1 is a Small Form-Factor Pluggable (SFP) optical transceiver designed for OC-3/STM-1 SONET/SDH intermediate reach applications. Operating at a data rate of 155 Mb/s, it supports transmission distances of up to 15 km over single-mode fiber (SMF) in compliance with the IR-1 (Intermediate Reach) standard. The module operates at a wavelength of 1310 nm and uses an LC duplex optical connector, ensuring compatibility with a wide range of Cisco networking and optical transport equipment. This transceiver is ideal for carrier networks, metro access links, and enterprise optical connections requiring stable, long-distance performance.
