Comet 1600R

Industrial G.SHDSL.bis EFM Modem

The Comet 1600R series industrial G.SHDSL.bis Ethernet extender is in compliance with EN50121-4 ETS EMC. This proves that not only can TAINET products operate and sustain on railways, but they can also work well under harsh conditions. Comet 160xR EFM series supports high-speed dedicated symmetrical data transmission and utilizes DSL bandwidth. The automatic adjusting line rate can be up to 15Mbps over 2-wire copper line symmetrically. Comet 1602R/1604R series typically works as an Ethernet extender, with up to 4 wires that could enhance the line rate and provide aggregated bandwidth up to 30Mbps.
  • Comet 1600R is a standalone model. For line card type compatible to iEAC-16, please refer to SNTU764
