AFBR-775BxxxZ / AFBR-785BxxxZ
Twelve-Channel Transmitter and Receiver
Pluggable, Parallel-Fiber-Optics Modules
Data Sheet
Description
Features
The AFBR-775BxxxZ Twelve-Channel, Pluggable, Parallel- • High Channel Capacity: 60 Gbps per module
Fiber-Optics Transmitter and AFBR-785BxxxZ Twelve-
Channel, Pluggable, Parallel-Fiber-Optics Receiver are
high performance fiber optics modules for short-range
parallel multi-lane data communication and interconnect
• High port density: 19 mm lateral port pitch; < 0.51 mm/
Gbps for Tx–Rx pair
• Low power consumption per Gbps: < 53 mW/Gb/s for
Tx–Rx pair
applications. The modules operate at 5.0Gbps per channel
over multimode fiber systems using a nominal wave- • Based on industry-standard, pluggable, SNAP12 form
length of 850 nm. Aggregate bandwidth per transmitter-
receiver link is 60G. The electrical interface uses a 10x10
MEG-Array® low-profile mezzanine connector. The optical
interface uses a MTP® (MPO) 1x12 ribbon cable connector.
The thermal interface can be a factory installed heatsink
for air-cooled systems or thermal seating plane for user
flexibility. The modules incorporate high performance,
factor with upgraded pinout for improved signal
integrity and keyed to prevent mis-plugging with first
generation SNAP12 devices
• Backed by PPOD MSA to enable multiple sources of
supply
• Twelve independent channels per module
highly reliable, short wavelength optical devices coupled • Separate transmitter and receiver modules
with proven circuit technology to provide long life and
consistent service.
• 850 nm VCSEL array in transmitter; PIN array in receiver
• Operates up to 5.0 Gbps with 8b/10b compatible coded
data
