Q

What is the difference between multimode cables in single node cables?

A

Multimode cables have a larger core diameter than single mode cables. The smaller 50 micron version can handle three times the bandwidth and supports longer cable runs than the 62.5 micron version. It transmits day approximately 600 meters.

Single core on the other hand is only 8 to 10 microns and is used for longer distance runs perhaps from one city to the next, in the thousands of kilometers. At shorter distances, single mode cable can go beyond 10 Gbps.

What is a digital technology developed to combat the limitations of PSTN where users can send data, talk on the phone, fax, all from one line?

A

Integrated Services Digitial Network (ISDN)

112
Q

ISDN has two types of services:

A

BRI: Basic Rate ISDN: 128 Kbps. Two equal B channels at 64 Kbps each for data and one separate 16 Kbps D channel for timing.

A

Digital Subscriber Line (DSL)

You can talk on the phone line and transmit data at the same time.

114
Q

There are two types of DSL:

A

ADSL (Asymmetrical Digital Subscriber Line): can run on your home telephone wine so that you can talk on the phone and access the Internet at the same time.
