ONS-SI-2G-S1-RF is a professionally remanufactured Cisco ONS SFP Transceiver Module for OC-48/STM-16 SONET/SDH optical networking, designed for use in Cisco ONS 15454 and compatible optical transport platforms. This module supports single-mode fiber connectivity at 2.5 Gbps line rates, making it well-suited for long-haul and metro optical transport deployments requiring precise wavelength and distance specifications.

This remanufactured SFP transceiver meets Cisco OEM specifications and has undergone thorough inspection and testing prior to shipment. Validation includes optical transmit and receive power verification, end-face fiber connector inspection, and functional compatibility testing within Cisco ONS chassis environments.

Key Features:
• 2.5 Gbps (OC-48/STM-16) data rate for SONET/SDH optical transport networks
• Single-mode fiber (SMF) support with LC duplex connector interface
• 1310 nm short-reach (SR-1/S-1) wavelength optimized for metro and access network spans
• Compliant with Cisco ONS 15454 MSTP and compatible optical transport platforms
• Small Form-factor Pluggable (SFP) form factor for hot-swap, tool-less installation
• Cisco IOS and CTC software recognition for seamless platform integration

This transceiver is ideal for network engineers, optical transport specialists, and telecom carriers managing or expanding SONET/SDH infrastructure who need a cost-effective, reliable alternative to new OEM modules. Choosing a remanufactured Cisco ONS-SI-2G-S1-RF delivers the same performance and platform compatibility as a new unit at a significantly reduced cost, making it an excellent choice for capacity expansions, sparing pools, or budget-conscious network upgrades without sacrificing quality or interoperability.
