– Twisted pair wire standards.
» There are two twisted pair cable pinout standards that are
regulated by TIA/EIA (Telecommunications Industry
Association/Electronic Industries Alliance). The pinout
standards specify the ordering of the wires to ensure that
proper networking communications can take place.
• TIA/EIA 568A (T568A).
• TIA/EIA 568B (T568B).
» All modern Ethernet networks that utilize unshielded twisted
pair (UTP) or shielded twisted pair (STP) use the TIA/EIA
standards.
– Common tools used with twisted pair
cable.
» Wire strippers are used to remove the insulating jacket from
the cable.
» Crimping tools are used to secure wires into modular
connectors.
» Punchdown tools are used to secure wires into a punchdown
block.
» Cable testers are used to test the integrity of a network cable.

– Distance limitations.
» Twisted pair is limited to 100 m without a repeater, unless
otherwise stated.
» Coaxial LAN is limited to either 185 or 500 m, depending on the
coaxial cable that is used.
• 10Base2: 10 Mbps, using RG-58, limited to 185 m.
• 10Base5: 10Mbps, using RG-8, limited to 500 m.
» Fiber optic LAN transmission is limited by the cable used; current
maximum is over 40 km over single-mode optical fiber (SMF).
– Twisted pair cable.
» 10BaseT: 10 Mbps, using UTP (minimum of Cat3).
» 100BaseT: 100 Mbps, using a minimum of Cat5.
» 100BaseTX: 100 Mbps, using two pair over a minimum of Cat5.
» 1000BaseT: 1 Gbps, using four pair over a minimum of Cat5e
» 1000BaseTX:1 Gbps, using two pair overa minimum of Cat5e.
» 10GBaseT: 10 Gbps, using a minimum of Cat6 (40 m).
» 10GBaseT: 10 Gbps, using a minimum of Cat6a (100 m).

– Multi-cable standard.
» 1000BaseX.
• 1000BaseSX: 1 Gbps over short distance multimode fiber
optic (MMF) (less than 2 km).
• 1000BaseLX: 1 Gbps over long distance SMF (greater than 2
km).
• 1000CX: 1 Gbps over coaxial cable up to 25 m.
– 10 gigabit networking.
» 10GBaseSR: over MMF, up to 300 m.
» 10GBaseLR: over SMF, up to 10 km.
» 10GBaseER: over SMF, up to 40 km.
» 10GBaseSW: over MMF, up to 300 m (SONET).
» 10GBaseLW: over SMF, up to 10 km (SONET).
» 10GBaseEW: over SMF, up to 40 km (SONET).
» 10GBaseLX4: over SMF, up to 300 m.
» 10GBaseLX4 over multimode: over MMF, up to 10 km.
» 10GBaseCX4: over InfiniBand copper cabling, up to 15 m.

– DOCSIS (Data Over Cable Service Interface
Specification).
» The standards that have been established to provide the
interface requirements for data transmissions over a broadband
cable network.
• To achieve the best performance when using broadband cable,
the cable modem should meet the highest DOCSIS standard
used by the cable provider.
» The most current standard is DOCSIS 3.1, which allows for up to
a theoretical maximum download speed of 10 Gbps with a
theoretical upload speed of 1 Gbps.
– IEEE 1905.1-2013.
» A standard that defines a network enabler (or device) that is
used to create a convergent home networking environment that
includes different types of wired and wireless networks.
• The standard also includes Ethernet over power line, which is
using the existing electrical wiring in a structure as the media
to transport data.
• The standard also includes Ethernet over HDMI, which is using
an HDMI interface and cable to transport network traffic.

Introduction to wired network standards.
The TIA/EIA is the organization that has established the commonly used
twisted pair wiring standards. The organization has specified two different
pinouts for UTP and STP wiring—T568A or T568B. All modern Ethernet
networks use these standards.
Topic
TIA/EIA 568A and TIA/EIA
568B.
Summary
All cables have a distance limitation. Twisted pair cabling has a normal limit
of 100 m. Coaxial cabling is limited to either 185 m or 500 m. Fiber optic
cabling is limited by type of cable and transmission type. The standards for
Ethernet have evolved over time and have gone from 10 Mbps to the more
current standard of 10 Gbps.
Ethernet standards.
DOCSIS are a set of specifications used in broadband cable that set the
standards required for the data interface for broadband cable networking.
The IEEE 1905.1-2013 standard defines a network enabler that can be
used in the home networking environment to bring convergence to wired
and wireless network media. It also provides specification for Ethernet over
power line and Ethernet over HDMI.
Other standards.
