Product Review

The CISCO SFP-10/25G-LR-S supports both 10G and 25G speeds with a link length of up to 10 km over single-mode fiber, catering to versatile networking demands. The requirement for RS-FEC (Reed-Solomon Forward Error Correction) at 25G operation introduces complexity but ensures data integrity over longer distances. Despite its efficient power consumption of 1.3 W, the module's performance is constrained by specific host port requirements and temperature ranges, which could limit deployment flexibility in varying environmental conditions.


The CISCO SFP-10/25G-LR-S is a dual-rate Small Form-Factor Pluggable (SFP) transceiver designed for use in 10-Gigabit and 25-Gigabit Ethernet links over single-mode fiber (SMF). It supports a link length of up to 10 kilometers at a wavelength of 1310 nm, making it an ideal solution for extended range data transmission requirements. This transceiver is compatible with the G.652 micron core size fiber, ensuring a wide compatibility with existing fiber infrastructure. This model is engineered to meet the demands of high-speed data networks, offering flexibility with 10GBASE and 25GBASE operation modes. For 25G operation, it necessitates RS-FEC (Reed-Solomon Forward Error Correction) on the host port to enhance signal integrity over longer distances. The transceiver’s maximum power consumption is modest at 1.3 watts, contributing to energy efficiency in data center environments. The CISCO SFP-10/25G-LR-S comes equipped with dual LC/PC connectors, providing a secure and reliable connection to the network. The inclusion of a blue pull tab or bail latch facilitates easy installation and removal, enhancing the usability of the device in densely populated network environments. It also supports Fibre Channel over Ethernet (FCoE), allowing for the integration of storage and data networking on a single platform for streamlined infrastructure and reduced costs. Key performance metrics include a maximum transmit power of 2.0 dBm and a minimum transmit power of -8.2 dBm at 10G, and for 25G, the minimum transmit power improves to -7 dBm. This ensures strong signal strength and reliable connectivity over the full 10 km link length. On the receiving end, the transceiver can handle a maximum power of 2.0 dBm and a minimum power of -14.4 dBm at 10G, with a slightly better minimum receive power of -13.3 dBm at 25G, ensuring compatibility with a range of signal strengths without compromising on performance.
  • Supports 10GBASE and 25GBASE operation modes for versatile network integration.
  • Dual LC/PC connectors ensure a reliable, secure fiber connection.
  • Energy-efficient design with a maximum power consumption of 1.3 watts.
Temperature tolerance is a crucial aspect of network hardware, and the CISCO SFP-10/25G-LR-S is built to operate within a broad range of environmental conditions. It can function within a commercial temperature range of 0 °C to 70 °C, and for more demanding environments, it can withstand industrial temperatures from -40 °C to 85 °C. This durability is extended to storage conditions as well, with the device capable of being stored within the same temperature range, ensuring long-term reliability. In summary, the CISCO SFP-10/25G-LR-S transceiver is designed for efficient and reliable long-range data transmission. Its support for both 10G and 25G operations, combined with low power consumption, robust temperature tolerance, and FCoE compatibility, make it a versatile and efficient choice for expanding enterprise and data center networks.
