SFP28 transceiver Extralink EX.33188 25G 1310 nm 10 km

Extralink EX.33188 is an SFP28 optical transceiver designed for 25G Ethernet links over single-mode fiber. Operating at a 1310 nm wavelength, this module supports data transmission up to 10 km and is compatible with standard SFP28 ports. Its hot-pluggable design enables insertion and removal without powering down the host device, making it suitable for data center uplinks, high-speed switch-to-switch connections, and router interfaces that require short to medium single-mode fiber runs.

Advantages

The transceiver delivers a stable 25G data rate with low latency and is engineered for compatibility with SFP28-compatible network equipment. Its single-mode 1310 nm operation provides a balance between reach and signal integrity for metropolitan and campus links. The hot-pluggable form factor simplifies maintenance and upgrades, while the compact SFP28 package conserves port density in switches and servers.

Suitable for

• 25G Ethernet uplinks between switches and routers
• Data center server connections requiring high bandwidth
• Short to medium single-mode fiber runs in campus networks
• Link aggregation and high-speed interconnects

Key specifications

• Form factor: SFP28 (hot-pluggable)
• Data rate: 25 Gbps
• Wavelength: 1310 nm
• Maximum reach: up to 10 km over single-mode fiber
• Connector type: LC duplex (industry standard for single-mode modules)
• Application: 25G Ethernet and compatible high-speed links

How to use

Insert the SFP28 transceiver into a compatible SFP28 slot on the switch, router, or host card until it locks into place. Connect a single-mode fiber patch cable with LC duplex connectors to the module. Ensure the connected equipment is configured for a 25G link and verify link status through the device management interface. The module supports hot insertion, so it can be installed or replaced without powering down the system; follow standard electrostatic discharge (ESD) precautions during handling.

Usage recommendations

For reliable operation, use single-mode fiber of appropriate grade and maintain clean LC connector end-faces. Verify transceiver compatibility with the specific network equipment firmware and monitor signal parameters after installation. Avoid exposing the module to excessive shock, vibration, or temperatures beyond manufacturer guidelines.
