FyberOptix 2m (7ft) NVIDIA/Mellanox MCA7J65-N002 Compatible 800G Twin-port OSFP 8 x 100G PAM4 Finned Top to 2 x 400G QSFP112 4 x 100G PAM4 InfiniBand NDR Active Direct Attach Copper Breakout Cable for Quantum-2 Switches and ConnectX-7 HCA

Description

Fyber Optix delivers fully tested, OEM-compatible optical transceivers, DWDM/CWDM systems, media converters and DAC/AOC cables — coded for Cisco, Huawei, Juniper, Arista, HPE, Dell, Nokia and Fortinet platforms, with lifetime warranty and fast global delivery.

The NVIDIA/Mellanox InfiniBand MCA7J65-N002 is a 2x 400Gb/s twin-port OSFP (Octal Small Form-factor Pluggable) finned top to dual 400G QSFP112 (Quad Small Form-factor Pluggable 112G) active direct attached copper breakout cable. The ACC contains eight high-speed electrical copper pairs, each operating at data rates of up to 100Gb/s using 100G-PAM4 modulation. It complies with IEEE 802.3ck, CMIS 5.0, OSFP Rev 5.0 and Q112 MSA standards. The OSFP end has a finned top for additional cooling, while the QSFP112 end is without cooling fins on top and uses the cooling fins located on the adapter cages. It is primarily used to link an 800Gb/s Quantum-2 switch to two QSFP112-based 400Gb/s ConnectX-7. ACC cables integrate a redriver chip that extends reach up to 5 meters while ensuring latency, enhancing port bandwidth, density, and configurability. These power-efficient links are ideal for medium-distance connectivity in data centers, AI/HPC clusters, and cross-rack deployments.

Fyber Optix is a British-engineered brand of OEM-compatible optical networking products, including SFP, SFP+, QSFP+, QSFP28 and QSFP-DD transceivers, DWDM/CWDM systems, media converters, and DAC/AOC cables. Every module is 100% pre-shipment tested and coded for seamless compatibility with major platforms such as Cisco, Huawei, Juniper, Arista, HPE, Dell, Nokia and Fortinet — backed by a lifetime warranty, fast global delivery, and dedicated technical support for data centers, telecom operators, enterprise networks and system integrators worldwide.
