BlueOptics QSFP-40G-LX4-MM Compatible 40GBASE-LX4 QSFP+ Transceiver, Duplex LC, 40Gbps, MMF/SMF, 150m OM3, 300m OM4, 2km SMF, CWDM 1271-1331nm, DDM, Hot-Pluggable QSFP-40G-LX4-MM-BO

The BlueOptics QSFP-40G-LX4-MM stands out by combining multi-mode and single-mode reach in a single QSFP+ module. While typical 40G LX4 optics are limited to one fiber type, this transceiver supports both OM3/OM4 multi-mode up to 300 meters and single-mode up to 2 kilometers, giving data centers flexible deployment options without changing hardware.

Highlights

• 40GBASE-LX4 QSFP+ transceiver with Duplex LC connector
• Supports multi-mode fiber (OM3: 150 m, OM4: 300 m) and single-mode fiber (2 km)
• CWDM wavelengths: 1271 nm, 1291 nm, 1311 nm, 1331 nm
• Digital diagnostics monitoring (DDM/DOM) for real-time parameter tracking
• Hot-pluggable and MSA compliant for easy installation
• Compatible with Cisco QSFP-40G-LX4-MM and other MSA-based equipment

In daily use

This transceiver is engineered for high-density 40 Gigabit Ethernet links in enterprise and data center environments. Its low power consumption (under 3.5 W) and wide operating temperature range (0°C to 70°C) ensure reliable performance in standard rack deployments. The integrated DDM allows network administrators to monitor optical power, temperature, and voltage, simplifying troubleshooting and maintenance.
