Cisco SFP-OC3-SR Compatible 155Mbps SFP Industrial Transceiver Module (SMF, 1310nm, 2km, LC, DOM)


The Cisco SFP-OC3-SR is a high-performance, small form factor pluggable (SFP) transceiver designed for short-range applications at speeds of 155Mbps, specifically for SONET OC-3 and SDH STM-1 networks. It fully adheres to the SFP Multi-Sourcing Agreement (MSA) and is compatible with networking equipment that follows MSA standards. This 155Mbps SFP transceiver comprises several key components: the LD driver, limiting amplifier, digital diagnostic monitor, FP laser, and PIN photo-detector. Furthermore, the SFP transceiver module falls under Class 1 laser product regulations, complying with FDA/CDRH and IEC-60825 standards. The SFP-OC3-SR transceiver has undergone rigorous testing to ensure compatibility with Cisco networking equipment, making it suitable for use in SONET/SDH (POS), optical networking, and ATM applications. It serves as a cost-effective alternative to the Cisco SFP-OC3-SR OC-3/STM-1 single-mode SFP optics module while delivering the same reliable performance. This makes it an excellent choice for system integrators, distributors, and end-users seeking compatible SFP optics transceiver solutions for their network infrastructure and fiber cabling needs.
