SFP-module Lancom SFP-LR-LC25 25GBASE-LR 10-pack

10-pack of Lancom SFP-LR-LC25 25GBASE-LR SFP modules designed for high-speed single-mode fiber links. Each module supports 25 Gbps transmission using LR optics with LC duplex connectors, offering long-reach optical connectivity for data centers, enterprise networks and telecom equipment. The modules follow the standardized SFP form factor for hot-swappable installation and broad compatibility with SFP ports that accept 25GBASE-LR optics.

Advantages

These SFP modules provide a compact, industry-standard solution for 25 Gbps fiber links over single-mode cables, combining high data throughput with LR optics optimized for extended distances. Hot-swappable SFP form factor minimizes downtime during maintenance or upgrades. LC duplex connectors and standardized electrical/optical interfaces enable interoperability with a wide range of switches, routers and transceivers that support 25GBASE-LR.

Suitable for

• Long-reach 25 Gbps connections in data center uplinks and spine-leaf fabrics
• Enterprise network backbone links between switches and aggregation points
• Telecom equipment and carrier-grade optical links requiring 25G LR optics
• Upgrading existing SFP ports to 25G performance without changing chassis

Key specifications

• Form factor: SFP (hot-pluggable)
• Data rate: 25 Gbps per module
• Optical type: LR (long reach) for single-mode fiber
• Connector: LC duplex
• Wavelength: designed for single-mode LR operation (typical in 1310 nm range)
• Temperature range: device-grade operating range suitable for networking equipment (check device documentation for exact limits)

How to use

Install each SFP module into an available SFP port on compatible network equipment while the device is powered on or following the manufacturer's hot-swap guidance. Connect LC duplex single-mode fiber patch cables to the module's LC connector and ensure correct TX/RX orientation. Verify link status and speed on the host device or management interface; configure interfaces for 25G operation if required by the switch or router. For multiple modules, deploy as needed to create parallel or redundant optical links.

Recommendations

Use single-mode fiber and LC duplex patch cords rated for LR distances; follow proper fiber handling and ESD precautions. Confirm that the host device supports third-party 25G SFP modules and enable any required interface settings. Maintain clean connector endfaces and inspect with a fiber microscope to prevent signal loss. Refer to system and fiber cabling documentation to match reach and power budget requirements for your specific deployment.
