Modulo ricetrasmettitore SFP28 BlueOptics WYMGJ-BO 25000 Mbit/s

The BlueOptics WYMGJ-BO is an SFP28 fiber optic transceiver module designed for 25GBASE-SR applications. It supports a maximum data transfer rate of 25000 Mbit/s over multimode fiber using an 850 nm transmitter and receiver and an LC duplex connector. The module follows MSA (Multi-Source Agreement) mechanical and electrical standards, has an aluminium housing and a lightweight design of approximately 20 g, and is intended for use in compatible networking hardware that supports standard SFP28 optics.

Advantages

The module provides 25 Gbit/s short-range connectivity with simultaneous send-and-receive capability via LC duplex connections and multimode fiber. It includes support for Digital Diagnostics Monitoring (DDM/DOM) compliant with SFF-8472, enabling readout of supply voltage, laser bias current, transmit power, receive power and temperature for remote monitoring and troubleshooting. Manufactured to MSA specifications, the transceiver is compatible with major vendor platforms that accept standard 25GBASE-SR SFP28 optics and is built with components chosen for long operational life and high availability.

Suitable for

• 25G Ethernet links within data centers and server rooms
• High-speed interconnects between switches, routers and storage systems
• Short-range multimode fiber connections up to typical OM3/OM4 distances (e.g., up to 100 m)
• Environments requiring digital diagnostics for link monitoring

Key specifications

• Interface type: SFP28
• Maximum data transfer rate: 25000 Mbit/s (25GBASE-SR)
• Wavelength: 850 nm (transmit and receive)
• Connector: LC duplex
• Compatible fiber type: Multimode fiber (MMF)
• Housing: aluminium; weight approx. 0.02 kg
• Digital diagnostics: DDM/DOM (SFF-8472 compliant)

How to use

Insert the BlueOptics WYMGJ-BO SFP28 module into a compatible SFP28 port until it latches according to the device manufacturer’s insertion procedure. Connect an LC duplex multimode fiber patch cable to the module; ensure transmit and receive fibers are correctly routed to the corresponding port on the far-end transceiver. Verify link status on the host device and, if supported, use the DDM/DOM interface to monitor optical power, temperature and other diagnostic parameters. Follow the host system’s guidelines for hot-plugging and static-safe handling.

Recommendations

Use OM3 or OM4 multimode fiber and high-quality LC duplex patch cords for optimal range and signal quality. Confirm that the target hardware vendor supports third-party SFP28 modules or enable any required compatibility settings in the host device. Avoid bending fiber cables beyond manufacturer-specified radii and keep transceiver dust caps on when ports are unused to protect optical interfaces.
