SFP28 transceiver module BlueOptics AFBR-735ASMZ-BO 25000 Mbit/s 850 nm

The BlueOptics AFBR-735ASMZ-BO is an SFP28 fiber optic transceiver module designed for 25 Gbit/s networks using multimode fiber. It operates at an 850 nm wavelength, provides LC duplex connectivity and supports maximum link distances up to 100 m. Housed in a silver SFP28 form factor and weighing approximately 40 g, the module follows MSA standards and offers CE, FCC and RoHS compliance with an MTBF of around 3,000,000 hours for long-term operation.

Advantages

The AFBR-735ASMZ-BO delivers a compact SFP28 solution that supports 25 Gbit/s data rates over multimode fiber, integrating transmit and receive functions at 850 nm. Compliance with industry MSA specifications ensures broad compatibility with common hardware platforms. Built from selected components, the transceiver offers digital diagnostics capability for remote monitoring and an expected service life consistent with a high MTBF value.

Suitable for

• High-speed server-to-switch uplinks in data centers

How to use

Install the SFP28 transceiver into an SFP28-compatible port on a switch, router or network device by sliding the module into the cage until it latches. Connect LC duplex multimode patch cables to the module's LC ports, ensuring correct transmit/receive orientation. Configure the connected device to enable the 25 Gbit/s interface and verify link status via the device management interface. If supported by the host, use the module's digital diagnostics monitoring (DDM/DOM) to check real-time parameters such as optical power and temperature.

Recommendations

Use shortwave 850 nm multimode fiber (OM3/OM4 recommended for best 25 Gbit/s performance) and quality LC duplex patch cords to achieve the specified 100 m range. Ensure the host hardware and firmware support SFP28 modules and the DDM/DOM feature if remote monitoring is required. Follow ESD handling procedures during installation and maintain clean fiber connectors to avoid signal loss.
