for 40 Gb and 10 Gb Ethernet Applications
Data Sheet
AFBR-79E3PZ
Description
Features
The Avago Technologies AFBR-79E3PZ is a Four-Channel,
Pluggable, Parallel, Fiber-Optic QSFP+ Transceiver with
integrated pull tab for 40 Gigabit Ethernet (40GbE) appli-
cations with extended reach up to 300 m (400 m) using
OM3 (OM4) multimode fiber (MMF) and with added capa-
bility of inter-operating with IEEE 10GBASE-SR compliant
products that can manage higher incoming optical power.
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 each lane operating at 10.3125 Gbps, giving an ag-
gregated bandwidth of 40 Gbps. This transceiver can also
be used for high density 10 Gigabit Ethernet applications.
It allows optical interoperability up to 300 m (400 m) using
OM3 (OM4) MMF with any 10 Gigabit Ethernet (10GbE)
transceivers, compliant to the IEEE 802.3ae 10GBASE-SR
specifications with a minimum 1 dBm of receiver overload.
It provides an effective port count of over 100 within 1 RU
rack. The pull tab facilitates the insertion and extraction
of these transceivers in such high density environment.
This transceiver is designated as a QSFP+ 3SR4 solution,
where the digit "3" represents 300 m link distance using
OM3 MMF.
These modules are designed to operate over multimode
fiber systems using a nominal wavelength of 850 nm. 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 Technolo-
gies proven integrated circuit and VCSEL technology to
provide reliable long life, high performance, and consis-
tent service.
