SFP transceiver module BlueOptics SFP28-25G-LR-IX-BO 25000 Mbit/s 1310 nm

The BlueOptics SFP28-25G-LR-IX-BO is a single‑mode fiber optic SFP28 transceiver module that supports data rates up to 25 Gbit/s using a 1310 nm wavelength. Housed in a compact metal enclosure and weighing approximately 2 g, the module provides an MSA‑compliant LC duplex interface for long‑reach fiber connections. It is designed for integration into network switches, routers, storage systems and other hardware that accepts SFP28 modules and supports 25GBASE‑LR optical links.

Advantages

This transceiver delivers 25 Gbit/s throughput over single‑mode fiber with LC duplex connectivity and a 1310 nm laser and receiver. The metal housing ensures mechanical durability and EMI resilience, while the low supply voltage requirement (3.3 V) and lightweight design simplify installation and reduce power budget. The module supports digital diagnostics monitoring (DDM/DOM) for remote monitoring of supply voltage, laser bias current, transmit power, receive power and temperature when used in compatible host hardware.

Suitable for

• 25GBASE‑LR long‑reach uplinks between switches and aggregation devices
• High‑performance connections in data center top‑of‑rack and spine architectures
• Fiber links for routers, load balancers and storage systems requiring 25 Gbit/s
• Environments where EMI immunity of fiber optics is required

• Optical wavelength: 1310 nm (transmit and receive)
• Media: single‑mode fiber
• Supply voltage: 3.3 V
• Housing: metal enclosure, silver colour
• Weight: approximately 0.002 kg

How to use

Install the SFP28 transceiver into a compatible SFP28 port on a switch, router or storage device following the host vendor's hot‑swap procedure. Connect the LC duplex single‑mode fiber patch cable to the module, ensuring correct transmit/receive orientation. Verify that the host platform supports 25GBASE‑LR operation and, if required, enable or validate link settings in the device management interface. If DDM/DOM is supported by the host, use the management tools to monitor optical and electrical parameters for ongoing diagnostics.

Recommendations

Use single‑mode LC duplex patch cords of appropriate quality and test the fiber path for insertion loss to achieve the specified reach. Confirm host compatibility with SFP28 25GBASE‑LR modules before deployment and ensure firmware or driver support if vendor locking is present. For reliable long‑term operation, operate the module within the host's specified temperature and voltage ranges and monitor DDM/DOM parameters periodically.
