BlueOptics QSFP-40G-UNIV-BO Compatible Arista QSFP+ 40GBASE-LX4 Transceiver, LC-Duplex, 40Gbps, OM4 160m / SMF 2km, 4xWDM, DDM

The BlueOptics QSFP-40G-UNIV-BO is a high-performance QSFP+ transceiver delivering 40 Gbps over fiber optic cabling. It supports both multimode OM4 fiber up to 160 meters and single-mode fiber up to 2 kilometers, making it a versatile choice for data centers and enterprise networks. Designed for compatibility with Arista QSFP-40G-UNIV, this hot-pluggable module ensures seamless integration and reliable performance.

Advantages

This transceiver leverages 4xWDM technology to combine four wavelengths on a single fiber pair, maximizing bandwidth efficiency. Digital Diagnostic Monitoring (DDM) provides real-time monitoring of critical parameters such as temperature, optical power, and voltage, enabling proactive network management. The LC-Duplex connector ensures secure and low-loss connections, while the wide operating temperature range from 0°C to +70°C guarantees stable operation in various environments.

Suitable for

• Data center interconnects requiring 40G Ethernet over multimode or single-mode fiber
• Enterprise backbone links where flexible reach options are needed
• Network upgrades from 10G to 40G without replacing existing fiber infrastructure
• Environments with Arista switches that support QSFP-40G-UNIV
