Data Sheet
Description
The Avago Technologies AFBR-79E4Z(-D) is a Four-Chan-
nel, Pluggable, Parallel, Fiber-Optic QSFP+ Transceiver for
40 Gigabit Ethernet Applications. This transceiver is a high
performance module for short-range multi-lane data com-
munication 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
100 m using OM3 fiber or 150 m using OM4 fiber. These
modules are designed to operate over multimode fiber
systems using a nominal wavelength of 850nm. The elec-
trical interface uses a 38 contact edge type connector.
The optical interface uses an 8 or 12 fiber MTP
connector. This module incorporates Avago Technolo-
gies proven integrated circuit and VCSEL technology to
provide reliable long life, high performance, and consis-
tent service.
