841717-B21 HP 40Gbps 40GBase-BIDI QSFP+ Bidirectional Transceiver Module

841717-B21 Overview

The HP 841717-B21 is a 40-Gigabit Ethernet QSFP+ bidirectional optical transceiver designed for high-speed data center interconnects over multi-mode fiber. Utilizing bidirectional transmission technology, it allows 40Gbps data rates to be carried over a single pair of MMF fibers, significantly reducing cabling complexity and cost. Operating over an 850nm wavelength range with WDM multiplexing, it supports link distances up to 100 meters on OM3 fiber and up to 150 meters on OM4 fiber. The module uses a standard duplex LC connector for easy integration with existing fiber infrastructure. It is hot-swappable, supports Digital Optical Monitoring (DOM) for real-time link performance tracking, and complies with IEEE 802.3ba and QSFP+ MSA standards.
