BlueOptics QSFP-40G-LR4-S-BO network transceiver module Fiber optic LC Silver

The BlueOptics QSFP-40G-LR4-S-BO is a 40GBASE-LR4 fiber optic QSFP network transceiver with an LC duplex connector. Designed to operate over single-mode fiber, it supports data rates up to 40 Gbps and is intended for use in QSFP-compatible switch, router and storage platforms. The module is RoHS compliant, weighs approximately 20 g and uses the QSFP electrical and mechanical form factor defined by MSA standards to ensure interoperability with compatible hardware.

Advantages

The transceiver supports 40G optical links over single-mode fiber with wavelength multiplexing (CWDM) on transmit and receive paths, providing simultaneous send and receive capability via LC duplex connections. It is produced according to MSA specifications for QSFP modules to enable plug-and-play interoperability with devices that accept 40GBASE-LR4 QSFP modules. Built with industry-standard optical components and digital diagnostics support, the module facilitates remote monitoring and fault analysis while offering a compact QSFP form factor for high-density installations.

How to use

Install the QSFP-40G-LR4-S-BO into a compatible QSFP port on a switch, router or other network device following the host vendor's hot-plug instructions. Connect LC duplex single-mode fiber patch cords to the module's LC connector, observing correct polarity for transmit and receive. Verify link status on the host device and, if supported, read digital diagnostic (DDM/DOM) parameters for supply voltage, laser bias current, optical power and temperature to confirm proper operation.

Recommendations

Use factory-tested single-mode LC patch cords and, where possible, route fibers through appropriate patch panels to preserve connector integrity. Ensure the host device firmware supports third-party QSFP transceivers and enable DDM/DOM in management software to monitor link health remotely.
