 Structure |
 |
|
|
| Features |
| |
Can transmit differential signals at speeds
of up to 500 Mbps or higher. |
|
The insulation is made of fully foamed olefin,
realizing low cost. Also, the unique construction enables the cable diameter to
be reduced. |
|
The conductor consists of highly flexible
stranded wire, resulting in excellent bendability and flexibility. |
|
The sheath is made of non-halogen fire retardant
polyethylene, which is kind to the environment. |
