Description
The Avago Technologies AFBR-7QERxxZ is a Four-
Channel, Pluggable, Parallel, Fiber-Optic QSFP+ Active
Optical Cable (AOC) solution for 40 Gigabit Ethernet
Applications. This AOC is a high performance cable for
short-range multi-lane data communication and inter-
connect applications. It integrates four data lanes in each
direction with 40 Gbps aggregate bandwidth. Each lane
can operate at 10.3125 Gbps. These cables also support
4 x 10 G InniBand QDR applications and are backwards
compatible to the 4 x 5 G IB DDR and 4 x 2.5 G IB single IB
SDR applications.
These Active Optical Cables operate over multimode ber
systems using a nominal wavelength of 850 nm. The elec-
trical interface uses a 38 contact edge type connector. This
AOC incorporates Avago Technologies proven integrated
circuit and VCSEL technology to provide reliable long life,
high performance, and consistent service.
