AFBR-79Q4Z, AFBR-79Q4Z-D
InfiniBand 4x QDR
QSFP Pluggable, Parallel Fiber-Optics Module
Product Brief
Description
The Avago Technologies AFBR-79Q4Z is a Four-Channel,
Pluggable, Parallel, Fiber-Optic QSFP Transceiver for QDR
InfiniBand and proprietary 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
aggregate bandwidth. Each lane can operate at 10 Gbps
up to 100 m using OM3 fiber. These modules are designed
to operate over multimode fiber systems using a nomi-
nal 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 cir-
cuit and VCSEL technology to provide reliable long life,
high performance, and consistent service.
