Description

The Arista AOC-Q-Q-40G-75M is a 40GbE QSFP+ Active Optical Cable (AOC) designed for high-density data centre interconnects requiring reliable 40 Gigabit transmission over multi-mode fibre at distances up to 75 metres. Built with 4 x 850nm VCSEL transmitters and 4 x PIN photo-detectors across parallel optical lanes, this AOC delivers up to 41.25 Gbps aggregate throughput without the need for discrete transceivers or patch cables — simplifying deployment and reducing cabling complexity in spine-leaf and top-of-rack architectures.

Compliant with the SFF-8436 QSFP+ MSA standard, this cable supports 40G Ethernet, InfiniBand QDR/DDR/SDR, and Fibre Channel applications, making it a versatile choice for mixed-workload environments. CE and RoHS certified, it integrates seamlessly with Arista switches, routers, and servers. In stock and ready to ship from iptrading.com.au — order now for fast dispatch.

Features

- QSFP+ MSA (SFF-8436) compliant — interoperable at both ends with standard QSFP+ ports
- Operates over Multi-Mode Fibre — no separate optical transceivers or patch cables required
- 4 x 850nm VCSEL transmitters with 4 x PIN photo-detectors for reliable parallel optical transmission
- Supports 40G Ethernet, InfiniBand QDR/DDR/SDR, and Fibre Channel applications in a single cable
- Plug-and-play compatibility with Arista switches, routers, and servers
- Cost-effective alternative to discrete transceiver-plus-cable solutions
- Low power consumption with high-density QSFP+ form factor — ideal for dense data centre deployments
- CE and RoHS certified for product safety and environmental compliance

FAQs

Q: What is the maximum distance supported by the AOC-Q-Q-40G-75M?
A: This Active Optical Cable supports 40GbE transmission at distances up to 75 metres over multi-mode fibre, making it suitable for intra-data centre interconnects between top-of-rack switches, spine switches, and servers.

Q: Is the AOC-Q-Q-40G-75M compatible with non-Arista equipment?
A: Yes. The cable is compliant with the SFF-8436 QSFP+ MSA standard, which means it is broadly compatible with any equipment featuring a standard QSFP+ port, including switches and servers from other vendors. Always verify compatibility with your specific platform before deployment.

Q: What is the difference between an AOC and a DAC (Direct Attach Cable)?
A: A Direct Attach Cable (DAC) uses copper conductors and is typically limited to shorter distances (up to ~7 metres for passive, ~15 metres for active). An Active Optical Cable (AOC) uses optical fibre with integrated transceivers, supporting much longer distances — up to 75 metres in this case — while maintaining a similar plug-and-play form factor.

Q: Does this cable require external optical transceivers?
A: No. The AOC-Q-Q-40G-75M has integrated optics at each QSFP+ connector end. There is no need for separate SFP+ or QSFP+ transceivers — it is a single, self-contained cable assembly.

Q: Which protocols and standards does the AOC-Q-Q-40G-75M support beyond 40G Ethernet?
A: In addition to 40G Ethernet (41.25 Gbps), this cable supports InfiniBand QDR (32 Gbps), DDR (16 Gbps), and SDR (8 Gbps), as well as 10G Ethernet, 10G Fibre Channel, and 8G Fibre Channel — making it suitable for high-performance computing (HPC) and storage networking environments.

Q: Can I purchase the Arista AOC-Q-Q-40G-75M in Australia from IP Trading?
A: Yes. IP Trading Australia stocks the AOC-Q-Q-40G-75M and offers fast dispatch from our Australian warehouse. Order online at iptrading.com.au or contact our team for volume pricing and availability.
