A cable, LAN interface standard

10Base-T: twisted pair cable, generally use the RJ-45 connector; the maximum effective transmission distance is a distance 100m hub, which makes high quality category 5 twisted pair can reach 150m. The matching electric resistance is 120 europe.

10BASE5: coaxial cable, using insert type tap; the baseband signal; maximum support long 500m, up to number 100. The matching electric resistance is 75 europe.

10base2: coaxial cable, connector using the industry standard BNC connector comprising type T socket; using a range of only 200 meters, each section can only use 30 computers, the highest number for the 30 paragraph. The matching electric resistance is 50 europe.

100base-tx: the use of the above 5 categories of twisted pair, segment length for 100m.

100Base-FX: using a pair of multimode and single-mode fiber, the use of multimode optical fiber when the computer to the hub, the distance between the largest available to the 2km, using single-mode optical fiber is up to 10km.

1000BASE-T: the use of the above 5 categories of twisted pair, segment length for 100m.

1000base-f: using a pair of multimode and single-mode fiber, the use of multimode optical fiber when the computer to the hub, the distance between the largest available to 300-550m ( 500m ), using single-mode optical fiber is up to 3km.

Two, WAN interface cable standard

E1: 64k-2mbps.

X25: the maximum rate of 64kbps.

Frame relay : the E1 circuit, rate may range from 64K to 2mbps.

V24: router end for db50 joint, external network terminal 25 pin connector.

Asynchronous mode, encapsulation Link Layer Protocol PPP, support network layer protocol IP and IPX, the maximum transfer rate was 115200bps;

Synchronous mode, can be packaged X.25, frame relay, PPP, HDLC, slip and LAPB link layer protocol, IP and IPX, and the maximum transmission rate is only 64000bps.

Transmission distance and transmission rate, 2400bps-60m: 4800bps-60m; 9600bps-30m; 19200bps-30m; 38400bps-20m; 64000bps-20m; 115200bps-10m.

V35: router end for db50 joint, external network terminal 34 pin connector.

V35 cable is generally used only for synchronous data transmission, can in the interface package X.25, frame relay, PPP, slip, LAPB link layer protocol, a network layer protocol IP and IPX support.

V.35 cable ( synchronous mode ) recognized the highest rate is 2048000bps ( 2Mbps ).

Transmission distance and transmission rate, 2400bps-1250m: 4800bps-625m; 9600bps-312m; 38400bps-78m; 19200bps-156m; 56000bps-60m; 64000bps-50m; 2048000bps-30m.
