SFP28 Transceiver Module BlueOptics AFBR-734TMZ-BO Fiber Optic LC

The BlueOptics AFBR-734TMZ-BO SFP28 Transceiver Module is a 25GBASE-SR compatible fiber optic transceiver designed for short-reach, high-speed networking. Featuring an LC duplex connector and multi-mode 850 nm transmit/receive optics, the module supports 2.5 Gigabit Ethernet and up to 25 G data rates on appropriate links and hardware platforms that support SFP28 modules. The transceiver is housed in an aluminium enclosure and weighs approximately 20 g, making it suitable for rack-mounted switches, routers and other network devices requiring compact, hot-pluggable optics.

Advantages

The module follows MSA standards for SFP28 form factor and LC duplex interfaces, providing broad interoperability with equipment that supports the original Broadcom AFBR-734TMZ 25GBASE-SR transceiver. Its multi-mode 850 nm optical design enables short-distance high-bandwidth links while fiber optics avoid electromagnetic interference. The aluminium housing offers mechanical robustness and thermal dissipation in dense installation environments. Digital diagnostics (DDM/DOM) support allows online monitoring of operating parameters when supported by the host device.

Suitable for

• Short-reach high-speed links in data center switching and aggregation
• Interconnects between switches, routers and storage systems using LC duplex multimode fiber
• Upgrades or replacements for SFP28-capable ports supporting 25GBASE-SR optics

Key specifications

• Form factor: SFP28 (MSA compliant)
• Wavelength: 850 nm (Tx/Rx)
• Supported transfer distance: up to 100 m over multimode fiber
• Connector type: LC duplex
• Supported interface: up to 25 G (backward-compatible with multi-rate links; supports 2.5 Gigabit Ethernet signaling)
• Housing material and colour: aluminium (aluminium colour)
• Weight: approx. 0.02 kg
• Digital diagnostics monitoring: supported when host hardware implements DDM/DOM

How to use

Install the SFP28 module into any compatible hot-pluggable SFP28 slot on your switch, router or storage device, ensuring the host hardware supports 25GBASE-SR optics and DDM if diagnostics are required. Connect LC duplex multimode fiber patch cords to the module, observing correct Tx-to-Rx pairing. After installation, verify link status and negotiated speed in the host device management interface. For short-reach links keep fiber runs within the specified maximum distance and use compatible multimode fiber types and patch panels to maintain signal integrity.

Recommendations

Use factory-tested multimode fiber cables (OM3/OM4) and maintain clean LC connector endfaces to ensure optimal performance. Confirm host equipment compatibility and enable DDM/DOM if available for remote monitoring of voltage, temperature, transmit/receive power and laser bias. Avoid exceeding recommended operating temperatures and handle the transceiver by its housing to prevent damage to the optical interface.
