Reliable short range 40G optics.
The QSFP-40G-BIDI-SR-MM850 is an MSA-compliant QSFP+ 40 Gbps BiDi optical transceiver designed for short-range (up to 100 m) multimode fiber applications at 850 nm.
It supports OM3/OM4 multimode fiber with standard MPO/MTP-12 connectors for bidirectional data transmission over a single fiber ribbon.
This module delivers reliable 40 Gbps connectivity up to 100 meters over OM3 multimode fiber and up to 150 meters over OM4.
It uses a bidirectional 850 nm laser for both transmit and receive channels, enabling full-duplex traffic on a single fiber.
BiDi technology employs two different optical wavelengths on one fiber ribbon—one for Tx and one for Rx—eliminating the need for separate transmit and receive fibers.
Yes, the QSFP-40G-BIDI-SR-MM850 is fully hot-swappable, allowing insertion or removal without powering down the host system.
It is compatible with QSFP+ ports on switches, routers, and network interface cards (NICs) from all major vendors that support MSA-compliant modules.
Yes, the module features 2-wire serial DDM for real-time monitoring of optical power, temperature, voltage, and laser bias current.
The transceiver operates reliably between 0 °C to 70 °C (32 °F to 158 °F) ambient temperatures.
It supports 40 Gigabit Ethernet (40GBASE-SR), InfiniBand FDR, and other 4×10 Gbps link aggregation applications.
Typical power consumption is ≤3.5 W, meeting stringent data-center power budgets.
Yes, it meets QSFP+ MSA, IEEE 802.3ba (40GBASE-SR), RoHS, and FCC Class B requirements.
Align the transceiver with the port guide rails and push firmly until it latches; release the module by pulling the extraction tab toward you.
Ideal for high-density data centers, spine-leaf architectures, and server interconnects requiring short-reach 40 Gbps links.
It includes a one-year manufacturer’s warranty and lifetime technical support with advanced replacement options.
