Compliance with RoHS, CE, FCC, and ISO9001 ensures quality and reliability.

## Long description

The BlueOptics QSFP-40G-LRL4-BO is a QSFP fiber optic transceiver module designed for high-speed data transfer at up to 40000 Mbit/s. Compatible with Arista Networks platforms that support 40GBASE-LR4L QSFP modules, this lightweight transceiver (0.004 kg) uses an LC Duplex connector and is intended for single-mode fiber links. The module complies with RoHS, CE, FCC and ISO9001 quality standards and supports CWDM-based transmit and receive channels for optical signal transmission over extended distances.
Advantages
The module provides MSA-compliant electrical, mechanical and functional interoperability, enabling plug-and-play installation in compatible switches, routers and storage systems. Built with industry-grade components and tested for compatibility with Arista Networks hardware, the transceiver offers digital diagnostics monitoring (DDM/DOM) for remote measurement of supply voltage, laser bias current, output power, received power and temperature. Low weight and standard QSFP form factor simplify handling and installation.
Suitable for
40 Gbit/s Ethernet connections over single-mode fiber
High-speed links between switches, routers and storage systems
Fibre Channel over Ethernet and SDH/SONET applications up to 2 km
Environments requiring DDM/DOM monitoring for optical links
Key specifications
Interface type: QSFP
Maximum data transfer rate: 40000 Mbit/s (40 Gbit/s)
Connector: LC Duplex
Optical type: single-mode fiber with CWDM channels
Typical range: up to approximately 2 km (per manufacturer application notes)
Product colour/finish: Nickel
Weight: 0.004 kg
Standards compliance: RoHS, CE, FCC, ISO9001; MSA-compliant QSFP form factor
How to use
Install the QSFP-40G-LRL4-BO into a compatible QSFP slot on Arista Networks hardware or other equipment that supports 40GBASE-LR4L QSFP modules. Connect an LC Duplex single-mode fiber patch cord between transceivers or to a patch panel, ensuring correct polarity. Verify that the host device firmware and software accept third-party transceivers and that DDM/DOM support is enabled if diagnostic monitoring is required. After insertion, check link status and DDM/DOM readings through the host management interface to confirm proper operation.
Usage recommendations
Use factory-tested single-mode LC Duplex patch cords and maintain proper fiber cleanliness to ensure optimal signal quality. Confirm host compatibility lists and enable digital diagnostics only if the host device supports DDM/DOM. For extended reliability, operate the transceiver within the equipment’s recommended temperature and power ranges and follow standard electrostatic discharge (ESD) handling procedures during installation and removal.
