SFP-lähetin-vastaanotinmoduuli Cisco SFP-10/25G-CSR-S=

The Cisco SFP-10/25G-CSR-S= is a compact fiber optic transceiver module designed for 10/25 Gbps data links. It supports a maximum data transfer rate of 25,000 Mbit/s and uses an 850 nm transmission wavelength with an LC connector interface. The module's small form factor and lightweight construction allow straightforward integration into compatible switches and routers for short-reach multimode fiber links.

Advantages

This transceiver provides high-speed data transmission up to 25 Gbit/s in a standard SFP form factor, enabling upgrades without replacing line cards. The use of an 850 nm wavelength ensures compatibility with common multimode fiber cabling and LC connectors. Its compact, low-profile design conserves port density on network equipment while supporting reliable optical connectivity. The product colour coding aids quick identification during installation and maintenance.

Suitable for

• Short-reach data center uplinks and switch-to-switch connections
• High-bandwidth server access over multimode fiber
• Aggregation links within campus and enterprise networks
• Environments requiring high port density and modular transceivers

Key specifications

• Maximum data transfer rate: 25,000 Mbit/s
• Operating wavelength: 850 nm
• Connector type: LC duplex
• Form factor: SFP (small form-factor pluggable)
• Compatible fiber type: multimode fiber (short-reach applications)
• Weight: approximately 200 g (module only)
• Product colour: green and grey

How to use

Ensure the host device supports SFP 10/25G modules and that firmware permits third-party or vendor-specific transceivers if required. Power down or follow hot-swap procedures recommended by the equipment vendor before inserting the transceiver into an available SFP port. Connect LC-terminated multimode fiber cables to the duplex LC connector, observing proper polarity. After installation, verify link status and interface configuration on the switch or router and confirm the negotiated speed and optics status through device management tools.

Recommendations

Use this transceiver in short-reach multimode fiber links within data centers or campus networks. Keep fiber connectors and transceiver ports clean and capped when not in use. Verify compatibility with the host equipment and check transceiver temperature and link diagnostics during commissioning to ensure stable high-speed operation.
