40G QSFP Breakout AOC

40G QSFP+Breakout AOC

T&S Communication TSQSS-8540G-xxxC is a Four-Channel, Pluggable, Parallel, Fiber-Optic QSFP+SR4 for 40 Gigabit Ethernet Applications. This transceiver is a high-performance module for short-range multi-lane data communication and interconnect applications. It integrates four data lanes in each direction with 40 Gbps bandwidth. Each lane can operate at 10Gbps up to 300 m using OM3 fiber. As a professional AOC factory in China, T&S mainly designs these modules to operate over multimode fiber systems using a nominal wavelength of 850nm. The electrical interface uses a 38 contact edge type connector. The optical interface uses a 12 fiber MTP (MPO) connector.

Features of 40G QSFP+Breakout AOC

  • Electrical interface compliant to SFF-8436 and SFF-8431

  • 850nm VCSEL laser and PIN photo-detector

  • Built-in digital diagnostic functions

  • Operating case temperature 0℃ to 70℃

  • Similar to the 40G AOC produced by T&S, this AOC breakout series is also hot Pluggable

  • RoHS compliant


Applications of 40G QSFP+Breakout AOC

  • 40GbE and 10GbE break-out applications for Datacom switch and router connections

  • 40G to 4×10G density applications for Datacom and Proprietary protocol applications, Datacenters
