Data Sheet
Description
The AFBR-811vx3Z Twelve Channel, Pluggable, Parallel
Fiber Optics Transmitter and AFBR-821vx3Z Twelve
Channel, Pluggable, Parallel Fiber Optics Receiver are high
performance fiber optics modules for short-range parallel
multi-lane data communication and interconnect applica-
tions. The high density optical modules are designed to
operate over multimode fiber systems using a nominal
wavelength of 850 nm. These MiniPODs can support
300m10GBASE-SR with Avago SFP+ transceivers over OM3
fiber.
Avago’s MiniPOD solution offers system designers two
module package options to optimize their cable manage-
ment and board layout. AFBR-811Rx3Z (Tx)/AFBR-821Rx3Z
(Rx) are used with round multi-lane cable assemblies for
applications requiring multiple turns of the jumper cable
inside the chassis. AFBR-811Fx3Z (Tx)/AFBR-821Fx3Z (Rx)
are used with flat ribbon cable assemblies, allowing dense
tiling of the modules as the jumper cables can be thread
under the dust-cap of the next module. This top mounted
optical connection maximizes board layout density by
eliminating board space lost to the optical connector and
strain relief.
The electrical interface uses a 9×9 MEG-Array connector
with 1.27 mm pitch (http://portal.fciconnect.com/
Comergent//fci/drawing/55714.pdf )
The optical interface requires the user to provide a
custom designed optical turn 1×12 ribbon cable PRIZM^
LightTurn^ connector.
The thermal interface provided can require either a user
provided heat sink or use of the Avago general purpose
clip on heat sink, to maintain the module case temperature
to be between 0 °C to 70 °C during continuous operation.
