Cisco QSFP-H40G-AOC2M Compatible 40G QSFP+ Active Optical Cable, OFNP Cable

Active Optical Cable (AOC) is a cabling technology that accepts same electrical inputs as a traditional copper cable, but uses optical fiber “between the connectors”. AOC uses electrical-to-optical conversion on the cable ends to improve speed and distance performance of the cable without sacrificing compatibility with standard electrical interfaces. Hangalaxy SFP28 Active Optical Cables are direct-attach fiber assemblies with SFP28 connectors. They are suitable for very short distances and offer a cost-effective way to connect within racks and across adjacent racks. This 25Gbps 850nm Multimode SFP28 Active Optical Cable is a single-Channel, Pluggable, Fiber-Optic SFP28 for 25 Gigabit Ethernet and Infiniband EDR Applications. It is a high performance module for short-range data communication and interconnect applications which operate at 25.78125 Gbps up to 70 m using OM3 fiber or 100 m using OM4 fiber. This module is designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The electrical interface uses a 20 contact edge type connector.

The rate of Hangalaxy 40G AOC cable is quite stable on our Cisco Nexus 9000 series equipment with no compatibility issue. Very pleased with my first order for nice products' performance. Regarding to my next project, will order FS products again.
