Custom 40G QSFP+ BiDi BDSR Module

Product Overview

Designed to shatter the physical cabling bottlenecks encountered when upgrading from 10G to 40G, the BiDi (BDSR) architecture provides a revolutionary migration path. While traditional 40G requires 8-core or 12-core MPO cables, this 40G QSFP+ BiDi BDSR Module integrates an internal optical duplexer. It superimposes two 20G data streams onto separate wavelengths, successfully completing the 40G signal loop over standard duplex LC patch cords.

Wholesale Pricing & OEM Advantage

Complex BiDirectional optics are notoriously expensive in the retail market. Sourced directly from Wolon’s Wuhan assembly lines, our 100m/150m BDSR modules are available to enterprise clients starting at just $93.75 USD. Supported by our 400+ manufacturing experts, we deliver customized, fully tested migration optics at a fraction of standard industry costs.

Frequently Asked Questions

Q: Does this module work with standard OM3/OM4 fiber, or do we need special cables? A: It works with your existing standard duplex LC OM3 or OM4 cables. You do not need to pull new MPO fiber. Just unplug your old 10G SR modules and plug these in.

Q: Is this 100% compatible with the Cisco QSFP-40G-SR-BD? A: Yes. We write the exact EEPROM code to match the Cisco QSFP-40G-SR-BD. Your Nexus or Catalyst switch will read it as an original part without any warning logs.

Q: Can a 40G BiDi module communicate with a standard 40G SR4 module? A: No. BiDi uses two wavelengths (usually 850nm and 900nm) on two fiber strands. SR4 uses four parallel 850nm lanes on eight fiber strands. They cannot link to each other.
