Belden Runs an Unamplified 1080p/60 Digital Video Signal Over 100ft of Connectorized HDMI Cable

“All HDMI cables are manufactured offshore in Asia, with one exception: the HDMI cable made by Belden,” states Steve Lampen, Product Line Manager at Belden. He continues, “However, this is just raw bulk cable. To be turned into assemblies, our partner Blue Jeans Cable (www.bluejeanscable.com) sends our bulk cable to China where it is cut and assembled with connectors. We currently make this raw cable in two gauge sizes, 23.5 AWG and 28 AWG, of which the 23.5 AWG is being demonstrated here at InfoComm, running what many say is impossible: a crystal clear 1080p/60 digital video signal over 100 feet.” The secret behind these Belden HDMI cables is the patented Bonded-Pair® technology.



Belden has used this technology for over sixteen years in Category 5, 5e, 6 and now Category 6A 10 gigabit (10GBASET) data cables. Bonded-Pairs attach the two insulated wires of each pair together, without any glue or bonding agent. This makes the most stable pair ever made, providing unequalled impedance tolerance. Even when the cable is flexed or bent, the conductor-to-conductor spacing remains constant. That means that the impedance also remains constant, and the problems of regular twisted pairs, such as impedance variations, are minimized. Impedance variations cause signal reflection (return loss). These variations also allow the signal to radiate off the cable (egress) and to pick up noise from other sources (ingress).



Reducing these effects allows cables made this way to run farther, with less signal loss, and less noise, than regular twisted pairs. While Belden makes bulk cable with Bonded-Pairs, we also make standard Nonbonded-Pair HDMI cables as assemblies in our factories in China. We believe these to be the highest quality Nonbonded-Pair HDMI cables, so our customers have a choice of Bonded-Pair or Nonbonded-Pair cables (HD2001-2007). All of these exhibit legendary Belden quality, performance, consistency, and reliability.
