25Gbps 850nm Multimode SFP28 Active Optical Cable

25Gbps, 850nm; SFP28 Active Optical Cable, OM3, OM4

General Details

TARLUZ 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 Multimode 850nm AOC 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 25.78125Gbps 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.
