Ricetrasmettitore SFP28 BlueOptics BO27Q856S1D (25GBASE-SR, LC-Duplex, MMF, 850nm, 100m, DDM, 0–70°C)

BlueOptics BO27Q856S1D is an SFP28 optical transceiver module designed for 25GBASE-SR short-range multimode fiber links. The module uses an LC-duplex connector and transmits at 850 nm wavelength, providing reliable 25 Gbit/s data rates over multimode fiber up to 100 m. It supports digital diagnostic monitoring (DDM/DOM) and operates within a 0–70°C temperature range, making it suitable for deployment in server racks, switch uplinks and data center patching where short-reach, high-bandwidth links are required.

Advantages

The transceiver offers industry-standard SFP28 form factor compatibility, enabling straightforward integration into compatible switches and network equipment. Its LC-duplex interface and 850 nm VCSEL-based optics deliver consistent performance for multimode fiber links up to 100 meters. Built-in DDM capabilities permit real-time monitoring of optical parameters such as temperature, transmit/receive power and supply voltage, supporting proactive maintenance and link diagnostics. The specified operating temperature range ensures stable operation in typical data center and telecom environments.

Key specifications

How to use

Install the SFP28 module into a compatible 25G-capable SFP28 port on a switch, server NIC or media converter, ensuring the module is properly seated and the device is powered according to the host equipment instructions. Connect LC-duplex multimode fiber patch cords with correct polarity and verify link lights and host system interface status. Use the host system or management tools to read DDM values for transmit/receive power, temperature and supply voltage to confirm proper operation. Follow the equipment vendor guidelines for hot-plug handling and electrostatic discharge precautions.

Recommendations

Use OM3/OM4 multimode fiber to achieve the maximum recommended 100 m reach and maintain clean, undamaged LC connectors to reduce insertion loss. Monitor DDM parameters periodically to detect signal degradation early. When deploying in dense rack environments, allow adequate airflow and adhere to the host device's temperature specifications to ensure reliable performance within the 0–70 °C operating range.
