25G SPF28 AOC

T&S Communication TSSP-8525G-xxxC 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 that 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. T&S 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.

Features of 25G SPF28 AOC

  • Electrical interface compliant to SFF-8431

  • 850nm VCSEL laser and PIN photo-detector

  • Maximum link length of 70m on OM3 MMF and 100m on OM4 MMF

  • Hot Pluggable

  • Built-in digital diagnostic functions

  • RoHS compliant



Applications of 25G SPF28 AOC

  • 25GBASE SR Ethernet, Data Centers

  • Infiniband transmission
