Telephone wire.
The beneficial effects of the utility model are:
1. guaranteeing that traffic rate the utility model utilizes VDSL technology using VDSL technology, VDSL technology uses frequency division multiplexing
Principle, data-signal and phone audio signal use different frequency ranges, do not interfere with each other, for technical standpoint, VDSL is actually
It may be regarded as the next-generation technology of ADSL, average transmission rate is higher by 5 to 10 times than ADSL.By conventional telephone line, use
Family can surf the Internet and enjoy higher transmission rate.Point-to-point connection may be implemented by the way that principal and subordinate is arranged, may be implemented symmetrical
Or uplink 60M, downlink 100M bandwidth may be implemented in asymmetric transmission, asymmetric transmission highest, symmetrical transmission may be implemented symmetrically
80M bandwidth.
2. extending communication distance the utility model of Ethernet using VDSL technology, again by Ethernet data coded modulation
It is transmitted, effectively extends the communication distance of Ethernet.The limit communication distance of Ethernet is 100 meters or so, and VDSL skill
Art can make the communication distance of Ethernet extend to 300~1000 meters, realize the ether Netcom of underwater robot and earth station
Letter.
3. reducing the core number of ethernet communication
4 cores used in ethernet communication or 8 core cables are reduced to the twisted pair of 2 cores by the utility model, are considerably reduced
The core number and diameter of communication cable, the use of the communication system significantly reduce the diameter of underwater robot umbilical cables.
The characteristics of the utility model is based on underwater robot, with VDSL technology, by cleverly conceiving and largely
