How different are Feeder 7/8 Telecom Coaxial Cable and Feeder 1/2 one?

What is Telecom Coaxial Cable?

Coaxial cable is a cable having a conductive core wrapped by a non-conductive dielectric layer, wrapped around by a twisted metal layer; the outer has an insulating sheath. “Coaxial Cable” means all cable layers share the same geometric axis. Coaxial Cable is invented by British mathematician and engineer - Oliver Heaviside, the patent was granted in 1880.

Telecom Coaxial Cables are used for installing Telecom projects

How many types of Telecom Coaxial Cables are there?

Telecom Coaxial Cables are classified into many types and each type has different characteristics so they have different effects.

- Hard Coaxial Cable

- Soft Coaxial Cable

- Low-attenuation Coaxial Cable

- Outer – Conductive - 3-Layer Cable

- Corrugated Coaxial Cable (Feeder)

Telecoms Coaxial Feeder has two types of dimensions which are widely used are Feeder 7/8 and Feeder 1/2.

The differences between Feeder 7/8 and Feeder 1/2.

Feeder 7/8 has a hollow copper pipe in the middle.

Feeder 1/2  has a solid copper fiber in the middle.

Feeder 7/8 with the maximum frequency of 5000 Mhz, attenuation level is 10.40 dB/100m and Consumed Energy is 0.96 Kw. Feeder ½ with the frequency of 5000Mhz, attenuation level is 0.476kw, Feeder 1/2 is still used with the frequency of 8000Mhz with attenuation level is 23.91db/100m and consumed energy is 0.358kw.

Over this comparison, we see that the Feeder 7/8' has lower attenuation but more consumed energy due to the feature of each type. Feeder 7/8 has a hollow-core in the middle and Feeder 1/2 has a solid core.

Feeder 7/8 has lower attenuation level, therefore, it is used to transmit for far distance; and Feeder 1/2 is used for transmission with nearer distance.
