Product Description
Broadcom AFBR-57H5MZ, 64GFC SFP56 for Multi-Mode Optical Fiber Digital Diagnostic SFP, 850-nm, 64G/32G/16G
The Broadcom AFBR-57H5MZ optical transceiver supports high-speed serial links over multi-mode optical fiber at signaling rates up to 57.8 Gb/s PAM4 (the serial line rate of 64GFC). The product is compliant with Small Form Pluggable SFP+ industry agreements for mechanical and low speed electrical specifications. High-speed electrical and optical specifications are compliant with ANSI Fibre Channel FC-PI-7.
The AFBR-57H5MZ is a multi-rate 850-nm transceiver that ensures compliance with FC-PI-7 64GFC, 32GFC and 16GFC specifications. Per the requirements of 64GFC, internal clock and data recovery circuits (CDRs) are present on both electrical input and electrical output of this transceiver. These CDRs lock at 57.8-Gb/s PAM4, 28.05-Gb/s NRZ and 14.025-Gb/s NRZ (64GFC, 32GFC, and 16GFC) accomplished by using two Rate Select inputs and I2C to configure transmit and receive sides.
Digital diagnostic monitoring information (DMI) is present in the AFBR-57H5MZ per the requirements of SFF-8472, providing real-time monitoring information of transceiver laser, receiver and environment conditions over an SFF-8431 I2C interface.
