Customized 40G QSFP+ to 8 LC AOC Breakout Cable


Bandwidth usage is soaring, driven by the proliferation of Internet-connected devices.  In this article, some knowledge of 40G QSFP+ to 8 LC AOC Breakout Cables will be provided.

40G QSFP+ to 8 LC AOC Specifications

40GBASE QSFP+ to eight LC/SC/ST/FC Connector Breakout Active Optical Cable is a high performance, low power consumption, long reach interconnects solution supporting 40G Ethernet, fiber channel and PCIe. It is compliant with the QSFP MSA and IEEE P802.3ba 40GBASE-SR4. QSFP+ Breakout Cable is an assembly of 4 full-duplex lanes, where each lane is capable of transmitting data at rates up to 10Gb/s, providing an aggregated rate of 40Gb/s. QSFP+ Breakout Cable is suitable for short distances and offers a highly cost-effective way to connect within racks and across adjacent racks. This product is a high data rate parallel active optical cable (AOC), to overcome the bandwidth limitation of traditional copper cable. Consequently, an aggregate data rate of 40Gbps over 100 meters transmission can be achieved by this product, to support the ultra-fast computing data exchange.

All our 40GBASE QSFP+ to LC/SC/ST/FC Connector(8) Breakout Active Optical Cable are 100% compatible with major brands like Cisco, Juniper, Enterasys, Extreme, H3C and so on.
