This high-performance 40-Gigabit QSFP+ transceiver revolutionizes network upgrades by enabling 40G connectivity over existing duplex LC multi-mode fiber infrastructure. Leveraging advanced bidirectional (BiDi) technology, it simultaneously transmits and receives data across two wavelengths (832nm to 918nm) on a single fiber strand, eliminating costly cable replacement needs. Supporting distances up to 150m on OM4 fiber or 100m on OM3 fiber, this transceiver is perfect for data center and enterprise networks. The module features built-in Digital Optical Monitoring (DOM) for real-time performance tracking and diagnostics, while operating efficiently on standard 3.3V power. Designed specifically for HPE Aruba and HPE ProCurve environments, this transceiver serves as an ideal bridge technology, replacing traditional 40G-SR4 modules that require 8-fiber MPO connectors. The robust construction and practical design make it an excellent choice for organizations seeking efficient 40G networking solutions without infrastructure overhaul. Manufactured in the USA, this TAA-compliant transceiver is suitable for federal government and military network deployments.
