Fiber Optics Link for DC to 10Mbaud

Currently Viewing:

Broadcom’ Fiber Optic (FO) Short Link is a cost-effective semiconductor product that provides 12 kV transient galvanic isolation on a single PCB. Based on 650 nm fiber optic technology, the FO Short Link is suitable for applications such as inverters/drives, power electronics, or medical equipment. The HFBR-3810Z and HFBR-3810MSZ devices offer creepage and clearance distances, with a minimum of 18.1 mm.
