CISCO XFP10GLR-192SR-L 10-2542-01 Module
Product Overview
The Cisco XFP10GLR-192SR-L is a low-power multirate XFP optical transceiver module supporting 10 Gigabit Ethernet (10GBASE-LR/-LW) and Packet-over-SONET/SDH (OC-192/STM-64) applications over single-mode fibre (SMF). It is designed to plug into XFP ports on Cisco routers and switches, enabling flexible 10 Gbps connectivity in enterprise and service-provider environments.
Key Features
• Supports both 10GBASE-LR/LW and OC-192/STM-64 SR-1 line rates in a single module.
• Uses 1310 nm wavelength for SMF links up to approximately 10 km.
• Low power consumption (approx. 1.5 W typical) thanks to “-L” low-power version.
• Hot-swappable XFP plug-in form-factor for minimal service disruption.
• Digital optical monitoring (DOM) support for transmit/receive power, temperature and voltage.
• Dual LC/PC connectors for optical interface.

Usage & Application
This transceiver is intended for deployment in 10-Gigabit Ethernet links or OC-192/STM-64 SONET/SDH environments where single-mode fibre runs up to around 10 km are needed. Ideal for uplinks, aggregation layers, campus backbone, or metro segments. Before purchase, verify compatibility with your hardware’s XFP port, firmware requirements, and that the fibre link meets SMF specification and connector type (LC).
Why Choose the Cisco XFP10GLR-192SR-L?
When you need a Cisco-qualified, multirate 10 Gbps optical transceiver that covers both Ethernet and packet/SONET applications, the XFP10GLR-192SR-L offers flexibility, low-power design and reliable performance. Its modest power draw, small footprint and broad compatibility make it a valuable option for high-density network infrastructures. While more recent form-factors (e.g., SFP+) may be available, this module remains a solid choice where XFP slots are present and long-reach single-mode fibre links are required.
