Cable joints are needed to connect cables with adequate interval.
Many joints
Many procedures of jointing Cost
Disturbing the traffic for a long time Public Safety
Troubles might occur at joints Reliability
Reduction the number of joints
Extend the cable length
Make much effort to extend the cable length
Why Long Cables are Useful?
