The AFBR-732BZ transmitter and AFBR-742BZ receiver are high performance fiber optic modules for parallel optical data communication applications. These 12-channel devices, operating up to 2.5Gbd per channel, provide a cost effective solution for short-reach applications requiring up to 30 Gb/s aggregate bandwidth. These modules are designed to operate on multimode fiber systems at a nominal wavelength of 850 nm. They incorporate high performance, highly reliable, short wavelength optical devices coupled with proven circuit technology to provide long life and consistent service. The AFBR-732BZ transmitter module incorporates a 12- channel VCSEL (Vertical Cavity Surface Emitting Laser) array together with a custom 12-channel laser driver integrated circuit providing IEC-60825 and CDRH Class 1M laser eye safety.
