Axiom Q40-40G-SR-BD-AX 40GBASE-SR-Bidi QSFP+ SFP transceiver MMF LC 150M 832NM-918NM

SKU CH-CYWH-JFE4W MPN Q40-40G-SR-BD-AX

A bidirectional QSFP+ transceiver for 40 Gbit links over multimode fibre up to 150 m using 832 nm and 918 nm wavelengths

  • 40 Gbps bidirectional throughput over a single fibre pair
  • 150 metre reach on multimode fibre with LC connector
  • 832 nm and 918 nm wavelengths enable bidirectional operation
  • MSA-compliant QSFP+ form factor fits standard switch ports
  • Pre-coded serialization prevents address conflicts in OEM systems

40GBASE-SR-BiDi QSFP+ Transceiver

The Axiom Q40-40G-SR-BD-AX is a bidirectional QSFP+ transceiver module designed for 40 Gigabit Ethernet links over multimode fibre. It suits network engineers upgrading or repairing switches and routers that accept MSA-compliant QSFP+ modules.

150 Metre Multimode Reach

This module operates over standard LC duplex multimode fibre with a maximum link distance of 150 metres. The bidirectional optics use distinct 832 nm and 918 nm wavelengths on a single fibre pair, so the practical limit is set by the 150 metre specification for OM3 or OM4 cable grades.

Single LC Port Bidirectional Design

The transceiver presents one LC connector carrying both transmit and receive paths through wavelength division multiplexing. Compatibility depends on the host equipment supporting 40GBASE-SR-BiDi optics and the correct 832 nm / 918 nm wavelength pairing.

Highlights

  • 40 Gbps bidirectional throughput over a single fibre pair
  • 150 metre reach on multimode fibre with LC connector
  • 832 nm and 918 nm wavelengths enable bidirectional operation
  • MSA-compliant QSFP+ form factor fits standard switch ports
  • Pre-coded serialization prevents address conflicts in OEM systems

Questions about this item

Which version of this QSFP+ transceiver should I select for a 40GBASE-SR bidirectional link?

The Q40-40G-SR-BD-AX model is the single 40GBASE-SR-BiDi variant offered; it uses an LC connector and operates at 832 nm and 918 nm over multimode fibre.

What does the 150 metre reach mean when the module is installed in a switch?

It supports a 40 Gbps bidirectional link up to 150 metres on OM3 or OM4 multimode fibre with LC duplex patch cords.

What interface standard does the QSFP+ form factor cap at for this module?

The QSFP+ interface carries four 10 Gbps lanes, delivering a 40 Gbps aggregate rate as defined by the 40GBASE-SR-BiDi specification.
