BROADCOM Transceiver 25ge Sfp28 For Multi-mode Optical Fiber 850nm

Avago Technologies’ AFBR-735SMZ optical transceiver supports high speed serial links over multi-mode optical fiber at 25.78Gb/s (the serial line rate of 25GE). The product is compliant with Small Form Pluggable industry agreements SFP and SFP28 for mechanical and low speed electrical specifications. High speed electrical and optical specifications are compliant with IEEE 802.3 for 25GBASE-SR and 10GBASE-SR.

The AFBR-735SMZ is a 850nm transceiver which ensures compliance with 25GBASE-SR specifications. Per the requirements of 25GE, internal clock and data recovery circuits (CDRs) are present on both electrical input and electrical output of this transceiver. These CDRs will lock at 25.78Gb/s but must be bypassed for 10GBASE-SR operation using two Rate Select inputs.

Digital diagnostic monitoring information (DMI) is present in the AFBR-735SMZ per the requirements of SFF-8472, providing real time monitoring information of transceiver laser, receiver and environment conditions over a SFF-8419 2-wire serial interface.
