This is generally because of improper cabling or termination. Most of you have probably seen ghosting on a TV set. I can think of several common examples: computer VGA cables, any TV antenna or cable TV wiring, telephone wiring, ethernet, SCSI, and firewire. The longer the cable, and the faster the data, the more critical this is. It is related to the ratio of cable capacitance per foot versus the cable inductance per foot. This IS NOT electrical resistance the way most people understand it. My simple explaination is as follows:Īny cable has a "characteristic impedance". There are important electrical specifications and termination issues. High-speed data cables are not simply how long, or how many connections there are. I would strongly caution anyone in this area. Than use gender connectors if you want a long cable. That's why it's best to splice a cable in between rather Just remember, the fewer the connections theīetter. I've made them as long as 30' by splicingĪ shielded multiconductor cable in between two firewire connectorsĪnd it works fine. You can make longer cables with the use of gender connectors or youĬan make one yourself if you are handy with a soldering iron and Two pin ,try good cable( usually is bigger one ) to make lowerĮlectric resistance.these two links blowwill show pictures how to then I trying to make a connecter that make two 3 meterįirewire cable become 6 meter.so far I have tried three 3 meterįirewire cables and two connecters to make a 9 meter firewire cableĪnd it works fine, but choose the cable inside connecter to connect If firewire cable longer then 3 M, it needed special older and costĪ lot. I was looking for a longer firewire cable ,but most people told me That's why it's best to splice a cable in between rather than use gender connectors if you want a long cable. Just remember, the fewer the connections the better. I've made them as long as 30' by splicing a shielded multiconductor cable in between two firewire connectors and it works fine. You can make longer cables with the use of gender connectors or you can make one yourself if you are handy with a soldering iron and some basic wiring skills.
