SFP28-transceiver BlueOptics 7G17A03538 25GBASE-LR LC-duplex singlemode 1310nm 10km DDM 0–70°C

BlueOptics 7G17A03538 SFP28 transceiver is a single-port module designed for 25GBASE-LR optical links over singlemode fiber. The module uses an LC-duplex connector and operates at a wavelength of 1310 nm to support data transmission up to 10 km. It includes Digital Diagnostic Monitoring (DDM) to report real-time parameters such as optical power and temperature, and is intended for use in 25 Gbps data center equipment, switches and routers within standard temperature environments.

Advantages

This SFP28 transceiver provides a compact, hot-pluggable form factor compatible with standard 25 Gbps interfaces, enabling easy upgrades of network equipment. The singlemode 1310 nm design delivers stable long-reach performance up to 10 km while minimizing dispersion for typical metro and data center links. Integrated DDM offers live monitoring of optical and electrical parameters to support maintenance and fault diagnosis. The module’s operating range suits standard ambient conditions common in server rooms and network closets.

Key specifications

How to use

Install the transceiver into an appropriate SFP28 port on a compatible switch, router or media converter while the host device is powered according to the vendor’s hot-plug guidelines. Connect LC-duplex singlemode fiber patch cables with correct polarity. Verify link status on the host device and monitor DDM parameters via the host management interface to confirm optical power levels and temperature are within expected ranges. Follow the equipment vendor’s instructions for firmware or compatibility settings if required.

Recommendations

Use singlemode fiber of suitable grade and quality, keep connectors clean and capped when not in use, and maintain correct fiber polarity. For reliable long-reach links, check optical budget calculations including loss from connectors and splices. Monitor DDM values periodically to detect signal degradation early, and operate the module within the specified temperature range for stable performance.
