Cable Lengths - Cabletron Systems T2015 Installation Manual

• Type 2 - Similar to Type 1 data cable, with four additional
unshielded twisted pairs of 24 AWG solid wire. The additional
wires are outside of the shield casing and are typically used for
voice communication. Type 2 is frequently used to wire cable
runs within the walls of buildings.
• Type 3 - Usually four unshielded twisted pairs (UTP) of 24
AWG solid wire for data or voice communication, such as
telephone lines. Used for cable runs in walls of buildings.
• Type 6 - Two STP of 26 AWG stranded wire for data. This type
is used in patch panels or to connect devices with wall jacks.
Due to the higher attenuation, Type 6 cable is good for up to 66
meters for every 100 meters of Type 1 cable (Type 6 cable
distance = 2/3 x Type 1 cable distance).
• Type 8 - One flat STP of 26 AWG stranded wire for under
carpet installation. Type 8 STP has the same characteristics as
Type 9 cabling.
• Type 9 - Similar to Type 1, but uses 26 AWG solid wire. Due to
the higher attenuation, Type 9 cable is good for up to 66 meters
for every 100 meters of Type 1 cable (Type 9 cable distance = 2/
3 x Type 1 cable distance).

3.3.2 Cable Lengths

Lobe length is the physical length of the cable connecting a PC to a
trunk coupling unit port on the ring concentrator. Lobe length
limits for the Token-Ring adapters are shown in Table 3-1 on the
following page. To determine the specific lobe link length, refer to
the manual for the concentrator to which your Token-Ring adapter
is connected.
