BlueOptics QSFP Transceiver A1DR-BO (40GBASE-SR4, MPO/MTP, Multimode, 4×850nm, 150m, 0–70°C)

The BlueOptics QSFP Transceiver A1DR-BO is a compact optical module designed for 40GBASE-SR4 links over multimode fiber. It uses an MPO/MTP interface with four parallel 850 nm transmit/receive lanes, providing short-reach 40 Gbit/s connectivity with a maximum reach of up to 150 meters on suitable multimode fiber. The transceiver operates across a 0–70°C ambient temperature range and is intended for high-density environments where IEEE 40G SR4 compatibility and compact QSFP form factors are required.

Advantages

This QSFP transceiver offers a small form factor suitable for high-density switch and server ports while supporting 40 Gbit/s aggregated bandwidth. The MPO/MTP multimode interface simplifies parallel fiber connections and patching in data center topologies. With four 850 nm lanes and a 150 m reach on multimode fiber, the module is appropriate for short-reach links such as switch-to-switch or switch-to-server interconnects in core and aggregation layers. The operating temperature range allows deployment in standard cooled equipment racks and telecom rooms.

How to use

Install the QSFP transceiver into a compatible QSFP slot on a switch, router or media converter following the host equipment manufacturer’s instructions for hot-plugging and module support. Connect an MPO/MTP multimode patch cable between the module and the matching MPO/MTP panel or transceiver on the remote device, ensuring correct polarity and fiber mapping for 40GBASE-SR4 parallel lanes. Verify link status and diagnostics via the host device management interface and perform optical budget checks if necessary to confirm reach on the installed multimode fiber.

Recommendations

Use OM3 or OM4 multimode fiber for reliable reaches up to 150 meters, maintain clean MPO/MTP connectors to minimize insertion loss, and verify that the host equipment supports 40GBASE-SR4 QSFP modules. Follow standard ESD precautions when handling the transceiver and consult fiber link loss calculations to ensure sufficient optical budget for your installation.
