Smart antenna modules get 1Gbit optical connectivity

October 11, 2017 // By Julien Happich
KDPOF announced a Gigabit Ethernet over Plastic Optical Fibres (GEPOF) transceiver for Integrated Smart Antenna (ISA) modules used on car roofs.

An ISA consists of several antennas for signal reception, an antenna hub, and an Ethernet connection routing the antenna signals inside the car. The antenna hub routes all signals from each antenna to an Ethernet network connected to all the receptors of the signals. Gigabit Ethernet over Plastic Optical Fibres (GEPOF) is well suited for the Ethernet connection due to its natural EMC-free property. The EMC problem-free link also allows simple re-positioning of the antenna module. Another advantage of optical connectivity for Smart Antenna Modules is the easy integration with current 100 Mbps designs thanks to the host bus of the GEPOF transceiver being “Ethernet compliant” (SGMII/RGMII). The data link can aggregate various packets such as LTE-A, Wifi, V2x, etc. and has enough bandwidth to be futureproof. KDPOF is now sampling its automotive grade GEPOF transceiver KD1053, compliant with the new IEEE standard amendment Std 802.3bv for Gigabit Ethernet over POF. It fully meets the requirements of carmakers by providing high connectivity with a flexible digital host interface, low latency, low jitter, and low linking time.
