## Summary description

The BlueOptics 40G-QSFP-LR4-INT-BO is a fiber optic transceiver module designed for high-speed data transmission over long distances up to 10000 m. It features a QSFP interface and is made of durable aluminum, weighing only 20 g. Ideal for data centers and high-performance networks.

## Long description

The BlueOptics 40G-QSFP-LR4-INT-BO is a 40GBASE-LR4 fiber optic QSFP transceiver module designed for high-speed single-mode fiber links up to 10,000 m. Housed in an aluminium enclosure and weighing approximately 20 g, the module provides a QSFP interface with LC Duplex connections and supports transmission and reception using CWDM channels. It is compatible with systems that accept MSA-compliant QSFP LR4 modules and is intended for use in data centers and high-performance network environments.
Advantages
This module offers 40 Gbit/s data throughput over single-mode fiber for long-reach connections up to 10 km while maintaining a compact, lightweight aluminium form factor. Built to MSA standards, it includes CWDM-based transmitter and receiver components and supports Digital Diagnostic Monitoring (DDM/DOM) for real-time status of supply voltage, laser bias current, transmit power, receive power and temperature when the host hardware exposes these diagnostics. The design emphasizes interoperability with MSA-compliant QSFP ports and reduced electromagnetic susceptibility inherent to fiber-optic links.
Suitable for
Long-reach 40 Gbps links in data center aggregation and core layers
Inter-switch and switch-to-router fiber connections over single-mode fiber
High-performance storage networks and SAN uplinks
Carrier and metro backbone links requiring 10 km reach
Key specifications
Interface type: QSFP (QSFP+ form factor compatible with 40GBASE-LR4)
Optical technology: LR4 with CWDM transmitter and receiver over single-mode fiber
Connector: LC Duplex
Maximum reach: up to 10,000 m (10 km) on single-mode fiber
Data rate: 40 Gbit/s aggregate
Housing material and colour: aluminium, aluminium-coloured housing
Weight: approx. 0.02 kg
Digital diagnostics: DDM/DOM support (host hardware must support access)
How to use
Install the QSFP transceiver into an MSA-compliant QSFP port on a switch, router or other compatible network device, ensuring proper orientation and a secure latch. Connect LC Duplex single-mode fiber patch cords between transceivers or to a patch panel, matching TX and RX pairs according to the link plan. Verify link status via the host device and, if available, use the DDM/DOM interface to monitor operating parameters. Follow the host vendor’s guidance for hot-plug procedures and for any vendor-specific enablement steps required for third-party modules.
Usage recommendations
Use quality single-mode LC Duplex patch cords and, where applicable, patch panels to preserve the specified 10 km reach. Ensure the host device firmware supports SFF-8436/SFF-8472 or equivalent MSA diagnostics for full DDM/DOM functionality. For installation and troubleshooting, observe ESD precautions and ambient temperature limits specified by the host hardware.
