Glasvezel-transceiver BlueOptics AFBR-79EQPZ 40000 Mbit/s QSFP 850 nm

The BlueOptics AFBR-79EQPZ is a fiber optic transceiver module engineered for 40 Gbit/s links using a QSFP form factor and an 850 nm wavelength. Designed for use in data center and enterprise networking equipment, the module supports high-speed short-reach connections over multimode fiber. Its compact dimensions and 30 g weight make it suitable for dense port deployments where space and thermal budgets are limited.

Advantages

The module delivers a maximum data transfer rate of 40000 Mbit/s through a QSFP interface, enabling aggregation and switch-to-switch connections at 40 Gbit/s. Operating at 850 nm, it is compatible with standard multimode fiber infrastructure, which simplifies integration into existing networks. The small, lightweight design reduces rack load and allows high port density installations while maintaining thermal efficiency and straightforward hot-pluggable replacement.

Suitable for

• 40 Gbit/s switch-to-switch links and uplinks in data centers
• Server aggregation and top-of-rack connectivity
• Short-reach multimode fiber connections within buildings and campus networks

Key specifications

• Interface type: QSFP (Quad Small Form-factor Pluggable)
• Maximum data transfer rate: 40000 Mbit/s (40 Gbit/s)
• Operating wavelength: 850 nm
• Form factor: QSFP transceiver module
• Weight: 0.03 kg

How to use

Install the BlueOptics AFBR-79EQPZ into a compatible QSFP port following the host device manufacturer’s hot-plug procedures. Connect the module to multimode fiber using appropriate LC/MTP adapters or cabling as required by the system. Verify link negotiation and speed settings on both ends of the link, and confirm optical power levels and alignment if prompted by the network equipment. For safe handling, avoid touching the optical interfaces and use dust caps when the module is not connected.

Recommendations

Use this transceiver for short-reach multimode applications where 40 Gbit/s bandwidth is required. Match the module to compatible QSFP-capable switches and patch panels, ensure multimode fiber type and connector compatibility, and operate within the device temperature and power specifications provided by the host equipment.
