The Avago Technologies AFBR-79EADZ is a Four-Channel, Pluggable, Parallel, Fiber-Optic QSFP+ Transceiver for 40 Gigabit Ethernet (40GbE) application.  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 aggregate bandwidth. Each lane can operate at 10.3125 Gbps up to 100m using OM3 fiber or 150m using OM4 fiber.  These modules supports 4 x 10G InfiniBand (IB) quadruple data rate (40G-IB-QDR) application and is backward compatible to the 4 x 5G IB dual data rate (20G-IBDDR) and 4 x 2.5G IB single data rate (10G-IB-SDR) applications as well.

These modules are designed to operate with an extended temperature range over multimode fiber systems using a nominal wavelength of 850nm. The electrical interface uses a 38 contact edge type connector. The optical interface uses an 8 or 12 fiber MTP® (MPO) connector. This module incorporates Avago Technologies proven integrated circuit and VCSEL technology to provide reliable long life, high performance, and consistent service.
