Portugal Telecom demos 100 Gbps over its optical fiber network
Portugal Telecom has demonstrated a 100-Gbps connection between Lisbon and Oporto using equipment from Alcatel-Lucent (Euronext Paris and NYSE: ALU). So this is about the entire world's communications. very important. So lets start with what is the optical fiber.
From wikii, An optical fiber is a thin, flexible, transparent fiber that acts as a waveguide, or "light pipe", to transmit light between the two ends of the fiber. The field of applied science and engineering concerned with the design and application of optical fibers is known as fiber optics.
The demonstration showcased end-to-end optical/IP 100-Gbps connectivity across an existing active DWDM link covering more than 400 km. The link used Alcatel-Lucent's 1626 Light Manager enhanced with 100G coherent technology and the Alcatel-Lucent 7750 Service Router equipped with 100 Gigabit Ethernet cards for IP/MPLS routing and services..
"In keeping with industry trends, we're expecting that video will account for well over half of our consumer traffic. This kind of demand requires higher-speed, higher-capacity technology," said Alfredo Baptista, Portugal Telecom CTO. "This fully integrated IP/optical 100G connection, together with the previously announced evolution of our fiber access network with GPON and 10GPON technologies [see "Portugal Telecom, Alcatel-Lucent to trial symmetrical 10G GPON"], is one further step towards a Next Generation Network with full end-to-end IP connectivity with high quality standards and very high speeds, being these unique characteristics not replicable on other type of technologies.
Portugal Telecom recently reaffirmed its commitment to invest in its optical fiber splicer network to the customer home with the objective of covering another 600,000 houses in addition to the over 1 million homes already serviced by the network. The network expansion will use about 300,000 km of fiber and shall involve approximately 1500 people between PT collaborators and external suppliers. Once complete, PT's fiber network will reach over 50% of homes in Portugal.
"The upgrading of service provider networks to 100G will be a major focus and business area for several years to come and these speeds will become the new currency of IP and optical networks," said Adolfo Hernandez, president of Alcatel-Lucent's activities in EMEA. "This demonstration brings to light the years of investment PT has made on future proof optical and IP infrastructure which is compatible with today's 100G technology."

Can anyone help me put these computer cables in progression from earlies to latest?
Fibre optic
10 base 2 (coaxil cable)
1000 baseT (Gigabit)
Cat6/Cat6e
10 BaseT (Cat5)
After putting them in order can you also tell me the
max reccomended distances for use
and other features/points to remember
help will be much appreciated.
the more explanatory answer will be voted as best answer

10 Base 2- 10Mbps Ethernet over thinnet (50 ohm) coaxial cable (RG-58) with a maximum segment distance of 185 meters. (it was rounded up to 10Base-2 instead of 10Base185). 10BAse-2 network isn't suited for connecting more than 10 computers. uses BNC connectors.
10BaseT- 10Mbps broadband implementation of Ethernet with a maxiumum segment lenght of 3,600 meters.
1000BaseT- Gigabit Ethernet over Category 5 or better UTP. Maximum distance is 100 meters from network-interface card to hub. The IEE designed 1000Base-T with intention of supporting Gigabit ethernet to the desktop. If you plan to deploy 1000baseT make sure that you use a minimum of Category 5e or better cable.
Fiber Optic- Single mode fiber optic cables can span distances up to 70 kilometers (43.5miles) without using signal-boosting repeaters.
Fiber Optics come in different flavors:
Single mode glass fiber core
Multimode Plastic-Clad Silica
Multimode Graded-index glass
Multimode Step-index
