Optical Fiber RX 75Gbps

The AFBR-786BxxxZ TwelveChannel, Pluggable, Parallel-Fiber-Optics Receiver is high performance fiber optics modules for short-range parallel multi-lane data communication and interconnect applications. The modules operate at 6.25Gbps per channel over multimode fiber systems using a nominal wavelength of 850 nm. Aggregate bandwidth per transmitterreceiver link is 75G. 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, highly reliable, short wavelength optical devices coupled with proven circuit technology to provide long life and consistent service.

• High Channel Capacity: 75 Gbps per module
• High port density: 19 mm lateral port pitch; < 0.51 mm/ Gbps for Tx–Rx pair
