SFP28-lähetin-vastaanotin BlueOptics ET7302-SR-BO 25000 Mbit/s kuitu

The BlueOptics ET7302-SR-BO is an SFP28 fiber optic transceiver module designed for 25GBASE-SR applications over multimode fiber. The module uses an LC duplex connector, supports a maximum data transfer rate of 25,000 Mbit/s and comes in a metal (silver) housing with a lightweight 20 g construction. With an MTBF of 1,000,000 hours, the transceiver is intended for use in high-speed network equipment that adheres to SFP28 MSA specifications.

Advantages

The transceiver complies with SFP28 MSA mechanical and electrical specifications and is engineered for interoperability with major hardware platforms that support 25GBASE-SR SFP28 modules. It offers simultaneous transmit and receive operation via LC duplex connections and is suitable for multimode fiber links up to typical short-range distances specified for 25GBASE-SR. Built with quality components and tested for compatibility and functionality, the module includes support for digital diagnostics (DDM/DOM) to monitor supply voltage, laser bias current, transmit power, receive power and temperature in real time.

Suitable for

• 25G Ethernet links in data centers and aggregation layers
• High-speed switch-to-switch or switch-to-server connections over multimode fiber
• Short-reach fiber links within campus, rack or cabinet environments
• Environments requiring digital diagnostics for remote monitoring of optical links

Key specifications

• Interface: SFP28 (LC duplex)
• Maximum data rate: 25,000 Mbit/s (25G)
• Optical wavelength (typical for SR): 850 nm transmitter and receiver
• Fiber type: Multimode fiber (MMF)
• Housing: metal, silver color
• Weight: 0.02 kg (20 g)
• MTBF: 1,000,000 hours
• Digital diagnostics: DDM/DOM support (MSA SFF-8472 compliant)

How to use

Install the BlueOptics ET7302-SR-BO into a compatible SFP28 port on switches, routers or other network devices that officially support 25GBASE-SR SFP28 modules. Connect an LC duplex multimode fiber patch cord between transceivers or to a patch panel, ensuring correct polarity for transmit and receive fibers. Verify link status on connected devices and, if available, use the DDM/DOM interface to monitor optical parameters and temperature. Follow the host device vendor instructions for hot-plugging and firmware or software settings that may affect third-party transceiver compatibility.

Recommendations

Use multimode fiber and patch cords rated for 25G short-range applications and verify that the network equipment firmware supports third-party SFP28 modules and DDM/DOM reporting. For optimal results, test the transceiver in the intended hardware platform before large-scale deployment and keep spare modules for rapid replacement to maintain network availability.
