AFBR-775BZ Twelve-Channel Transmitter and Receiver Pluggable, Parallel-Fiber-Optics Modules

Description

The AFBR-775BZ Twelve-Channel, Pluggable, Parallel- Fiber-Optics Transmitter and AFBR-775BZ Twelve- Channel, Pluggable, Parallel-Fiber-Optics Receiver  are  high performance fiber optics modules for short-range parallel multi-lane data communication and interconnect applications. The modules operate at 5.0Gbps per channel over multimode fiber systems using a nominal wave- 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 cableconnector. 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, highly reliable, short wavelength optical devices coupled with proven circuit technology to provide long life and consistentservice.

resumes. All interrupts can be masked and flags are reset upon reading the appropriate flag register.  The  elec-  trical output will squelch for loss of input signal (unless squelch is disabled) and channel de-activation through TWS interface. Status and alarm information are available via the TWS interface. The interrupt signal (selectable via the TWS interface as a pulse or static level) is provided to inform hosts of an assertion of an alarm and/orLOS.
