Cisco QSFP-H40G-AOC20M Full English Product Description

Cisco QSFP-H40G-AOC20M is an original Cisco 40GBASE-AOC QSFP+ to QSFP+ Active Optical Cable (AOC) with a fixed length of 20 meters. This fully integrated fiber cable assembly embeds VCSEL optical transmitters and PIN photodiode receivers inside QSFP+ connectors at both ends to implement electro-optical signal conversion. Compliant with QSFP+ MSA SFF-8436 and IEEE 802.3ba standards, it delivers superior electromagnetic interference immunity and flexible cabling solutions for ultra-long-distance intra-rack and cross-rack 40-Gigabit point-to-point interconnections in enterprise and cloud data centers, covering transmission distances exceeding the operating range of copper direct attach cables.

40 Gbps Full-Duplex Optical Transmission

Supports 40GBASE Ethernet over four independent 10Gbps optical lanes, delivering stable bidirectional 40G throughput for leaf-spine network fabrics, switch-server interconnections and high-speed storage networking infrastructure.
Active Electro-Optical Conversion Architecture

Built-in VCSEL transmitters and PIN photodiode receivers convert electrical signals into optical signals. Optical transmission completely isolates electrical noise, eliminating EMI/RFI interference and crosstalk limitations encountered with twinax copper DAC cables.
Lightweight & Flexible Fiber Construction

Thinner, lighter and more pliable than copper twinax cables, meeting strict minimum bend radius requirements, improving cabinet airflow and facilitating neat cable management within high-density rack environments.
Hot-Swappable QSFP+ Interface

Standard hot-pluggable QSFP+ form factor allows technicians to install or remove the cable without powering down connected switches, routers and servers.
850nm Short-Wave Multimode Operation

All-in-one integrated design removes the requirement for separate optical transceivers and discrete fiber patch cords, simplifying end-to-end data center cabling architecture.
Green Color-Coded Pull Tab Design

Equipped with green pull-tab latches for convenient insertion and extraction from QSFP+ ports on network hardware.
