AFBR-79EIZ, AFBR-79EIDZ
40G-iSR4 QSFP+ Pluggable, Parallel Fiber-Optics Module
for 40Gigabit and 10Gigabit Ethernet Applications
Data Sheet - Preliminary
AFBR-79EIZ
Description
Features
The Avago Technologies AFBR-79EI(D)Z is a Four-Channel, x Compliant to the 40GbE Specification IEEE 802.3ba
Pluggable, Parallel, Fiber-Optic QSFP+ Transceiver for 40
D3.2 (40GBASE-SR4)
Gigabit Ethernet (40GbE) applications with added capa- x Support interoperability with IEEE 802.3ae 10GBASE-
bility of inter-operating with IEEE 10GBASE-SR compliant
products. This transceiver is a high performance module
for short-range multi-lane data communication and in-
terconnect applications. It integrates four data lanes
ATAin each direction with each lane operating at 10.3125
Gbps, giving an aggregated bandwidth of 40 Gbps. This
transceiver can also be used for high density 10 Gigabit
Ethernet application to allow effective port count of over
D100 within 1 RU rack. It allows optical interoperability with
any 10 Gigabit Ethernet (10GbE) transceiver, compliant
Yto the IEEE 802.3ae 10GBASE-SR specifications, of form
Rfactors such as SFP+, XFP and X2. This transceiver is desig-
Anated as a 40G-iSR4 solution, where the letter i represents
interoperability between this QSFP+ transceiver with any
IN10GBASE-SR compliant modules.
This QSFP+ transceiver link length for either 40 Gigabit
ELIMEthernet or high density 10 Gigabit Ethernet application
is 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
electrical interface uses a 38 contact edge type connector.
PRThe optical interface uses an 8 or 12 fiber MTP£ (MPO)
SR modules of various form factors such as SFP+, XFP,
and X2
x Compliant to the industry standard SFF-8436 QSFP+
Specification Revision 3.5
x Power Level 1: Max Power <1.5W
x High port density: 21mm horizontal port pitch
x Operates at 10.3125 Gbps per channel with 64b/66b
coded data
x Links up to 100m using OM3 fiber and 150m using
OM4 fiber
x 0 to 70°C case temperature operating range
x Proven High Reliability 850 nm technology: Avago
VCSEL array transmitter and Avago PIN array receiver
x Hot pluggable transceiver for servicing and ease of
installation
x Two Wire Serial (TWS) interface with maskable
interrupts for expanded functionality
x Utilizes a standard 12/8 lane optical fiber with MTP£
(MPO) optical connector for high density and thin,
connector. This module incorporates Avago Technolo-
light-weight cable management
gies proven integrated circuit and VCSEL technology to
provide reliable long life, high performance, and consis- Applications

Recommended Operating Conditions
Recommended Operating Conditions specify parameters for which the optical and electrical characteristics hold
unless otherwise noted. Optical and electrical characteristics are not defined for operation outside the Recommended
Operating Conditions, reliability is not implied and damage to the module may occur for such operation over an
extended period of time.

D3. Power Supply Noise is defined as the peak-to-peak noise amplitude over the frequency range at the host supply side of the recommended power
supply filter with the module and recommended filter in place. Voltage levels including peak-to-peak noise are limited to the recommended
Yoperating range of the associated power supply. See Figure 9 for recommended power supply filter.

Note:
1. Power On Initialization Time is the time from when the supply voltages reach and remain above the minimum Recommended Operating Conditions
to the time when the module enables TWS access. The module at that point is fully functional.

Notes:
1. GND is the symbol for signal supply (power) common for the QSFP+ module. All are common within the
QSFP+ module and all module voltages are referenced to this potential unless otherwise noted. Connect
these directly to the host board signal-common ground plane
2. Vcc Rx, Vcc1 and Vcc Tx are the receiver and transmitter power supplies and shall be applied concurrently.
