SFP28 Transceiver BlueOptics ESPT251SR1UCL100-BO — LC-Duplex, 25GBASE-SR, Multimode 850nm, 100m, DDM/DOM, 0–70°C

BlueOptics SFP28 Transceiver ESPT251SR1UCL100-BO is a 25GBASE-SR multimode fiber module with an LC-duplex interface that operates at a wavelength of 850 nm. The module supports data transmission up to 25 Gbit/s over multimode fiber for distances up to 100 meters and includes digital diagnostics monitoring (DDM/DOM). It is specified for operation in ambient temperatures from 0°C to +70°C, making it suitable for standard data center and enterprise networking environments where short-reach 25 Gigabit Ethernet links are required.

Advantages

The transceiver provides reliable short-reach 25G connectivity with an industry-standard LC-duplex connector and low-power SFP28 form factor. Built-in DDM/DOM enables real-time monitoring of optical and electrical parameters such as optical power and temperature. Compatibility with multimode 850 nm fiber and a 100 m reach simplifies upgrades in existing OM3/OM4 fiber infrastructures. Specified operating temperature range ensures predictable performance within typical server room and rack environments.

How to use

Install the BlueOptics SFP28 transceiver into an SFP28-compatible port on a switch, router or network interface card following the host device manufacturer’s hot-plug procedures. Connect LC-duplex multimode fiber patch cables (850 nm compliant) to the module ensuring correct polarity. After insertion and link establishment, verify link status and use the host system or supported management tools to view DDM/DOM parameters for optical power, temperature and other diagnostics. If the device does not bring the link up, check fiber type, cable length, connector cleanliness and port configuration.

Recommendations

For reliable performance, use OM3 or OM4 multimode fiber and high-quality LC duplex patch cords, maintain clean connector endfaces, and observe the specified 0°C to +70°C operating temperature. Use DDM/DOM readings to monitor link health and plan maintenance or replacement if optical power or temperature values deviate from expected ranges.
