the cable. Since the cable is shielded, signal reflection
has little effect on the received signal’s quality, due to
the lack of crosstalk between the shielded cable pairs.
Cabletron Systems’ 10BASE-T Twisted Pair products
work on shielded twisted pair cable with 75 to 165
ohms impedance.
•
Jitter
- Intersymbol interference and reflections can
cause jitter in the bit cell timing, which results in data
errors. A 10BASE-T link must not generate more than
5.0 ns of jitter. If your cable meets the impedance
requirements for a 10BASE-T link, jitter should not be
a concern.
•
Delay
- The maximum propagation delay of a
10BASE-T link segment must not exceed 1000 ns.
This 1000 ns maximum delay limits the maximum link
segment length to 200 meters.
•
Crosstalk
- Crosstalk is caused by signal coupling
between the different cable pairs contained within a
multi-pair cable bundle. 10BASE-T transceivers are
designed so that you do not need to be concerned about
cable crosstalk, provided the cable meets all other
requirements.
•
Noise
- Noise is caused by either crosstalk or
externally induced impulses. External noise can cause
