SFP28-lähetin-vastaanotin CBO SFP28-25G-ESR-IB-BO 25 Gbit/s LC 300 m

The CBO SFP28-25G-ESR-IB-BO is a 25 Gbit/s SFP28 optical transceiver with an LC duplex connector and a maximum reach of up to 300 metres over single-mode fiber. It is designed to provide single-port 25G connectivity for switches, routers and servers in data center and enterprise environments. The module supports high-speed uplinks and short-range fiber interconnects where reliable 25G performance and compact SFP28 form factor are required.

Advantages

The transceiver combines compact SFP28 form factor with 25 Gbit/s line rate and an LC duplex interface, allowing straightforward integration into existing 25G-capable ports. With a reach of up to 300 m over single-mode fiber and industry-standard electrical and optical specifications, the module supports predictable latency and stable data transfer for high-density racks and aggregation switches. The product is suitable for hot-pluggable deployment and interoperates with common 25G networking equipment that supports SFP28 optics.

Suitable for

• 25G uplinks between top-of-rack switches and aggregation switches
• Server network interfaces requiring 25G fiber connectivity
• Short-range single-mode fiber links inside data centers or enterprise campuses (up to 300 m)
• Interconnects between network devices in high-density rack deployments

Key specifications

• Nominal data rate: 25 Gbit/s
• Connector type: LC duplex
• Maximum reach: up to 300 metres over single-mode fiber
• Form factor: SFP28
• Wavelength window: optimized for 25G single-mode links
• Hot-pluggable optical module

How to use

Install the SFP28 transceiver into a compatible SFP28 port on a switch, router or server until it latches. Connect LC duplex single-mode fiber patch cords ensuring correct transmit-to-receive orientation. Confirm link negotiation and port configuration on the host device to enable 25 Gbit/s operation and verify signal levels and error counters through device management interfaces. For hot-swap replacement, remove the module by disengaging the latch and pulling it straight out, then insert the replacement module following the same steps.

Recommendations

Use single-mode fiber rated for 25G performance and quality LC patch cords to achieve the specified reach. Validate compatibility with the host equipment’s optics policy and firmware. Avoid excessive bending or stress on fiber cables and observe ESD precautions when handling the module.
