## Summary description

The BlueOptics QSFP-40G-LR4L-TM-BO is a fiber optic transceiver module with a maximum data transfer rate of 40000 Mbit/s. It features a QSFP interface and is made of metal, weighing 40 g. Ideal for high-speed data communication in networking applications.

## Long description

The BlueOptics QSFP-40G-LR4L-TM-BO is a metal QSFP fiber optic transceiver module designed for 40 Gbit/s optical links over single-mode fiber. It uses an LC duplex connector and supports 40GBASE-LR4L transmission with CWDM on transmitter and receiver stages, enabling high-speed data transfer up to 40,000 Mbit/s over distances up to approximately 2 kilometers when used with appropriate single-mode cabling and compatible hardware platforms.
Advantages
This QSFP transceiver is manufactured to MSA standards and is compatible with Transmode platforms, offering tested interoperability with switches, routers, storage systems and similar network equipment that support the original Transmode 40GBASE-LR4L QSFP. Built with quality components such as high-performance lasers and proven ICs, it provides long operating life and high availability. The module includes Digital Diagnostics Monitoring (DDM/DOM) functionality for real-time monitoring of supply voltage, laser bias current, optical transmit/receive power and temperature.
Suitable for
40 Gbit/s Ethernet uplinks and aggregation links
Fibre Channel over Ethernet and SDH/SONET high-speed connections
Interconnects between switches, routers and storage systems within data centers
Longer single-mode fiber links up to roughly 2 km with LC duplex connectors
Key specifications
Interface: QSFP form factor
Maximum data rate: 40,000 Mbit/s (40 Gbit/s)
Optical standard: 40GBASE-LR4L with CWDM transmitter and receiver
Connector type: LC Duplex
Fiber type: Single-mode fiber
Housing: Metal, silver color
Weight: 0.04 kg
Digital diagnostics: DDM/DOM (MSA SFF-8472 compliant)
How to use
Insert the QSFP transceiver into a compatible QSFP port on supported network hardware following the device manufacturer's hot-plug guidelines. Connect LC duplex single-mode fiber patch cords to the module's transmit and receive connectors, ensuring correct polarity and appropriate patching to the remote transceiver. Confirm that the host device firmware or software accepts Transmode-compatible modules and, where available, enable or check DDM/DOM readings for link diagnostics. Use appropriate optical power budgets and link-loss calculations to ensure reliable operation within the specified reach.
Usage recommendations
Use high-quality single-mode LC duplex patch cords and, if possible, route fibers via patch panels to maintain optimal link performance. Verify hardware compatibility and DDM/DOM support before deployment. For long-term reliability, follow standard handling precautions for optical transceivers: avoid contamination of fiber endfaces, operate within specified temperature and power ranges, and ensure proper ESD protection during installation and removal.
