40GBASE-SR4 QSFP+ multimode fiber optic module with MPO interface for short-reach data center interconnects.
When high-bandwidth interconnects are required for short-reach data center links, reliable multimode optics prevent signal degradation. The LRFQ8540-X1ATM 40G QSFP+ fiber optic module addresses this need for 40GBASE-SR4 Ethernet applications.
Delivering 40Gb/s total bandwidth across four 10Gb/s full-duplex channels, this module ensures consistent throughput for switch-to-server connections. Its 850nm VCSEL array technology supports distances up to 150m on OM4 fiber, enabling flexible rack cabling without repeaters. Digital diagnostic monitoring allows real-time performance tracking to minimize downtime.
Designed for 40GBASE-SR4 and 4x10GBASE-SR breakout deployments, this QSFP+ MSA-compliant module offers a low-power interconnection solution. It provides verified compatibility for enterprise network upgrades requiring standardized multimode optics.
Provides 40Gb/s total rate with 4 independent 10Gb/s full-duplex channels for 40GBASE-SR4 Ethernet.
Supports transmission distances up to 100m on OM3 and 150m on OM4 multimode fiber.
Features digital diagnostic monitoring for real-time performance tracking and troubleshooting.
Conforms to IEEE P802.3ba, SFF-8436 standards and QSFP+ MSA specifications.
High-performance, low-power consumption design with single +3.3V power supply.
