Write some advantages and disadvantages of optical fibres.

Some advantages of optical fibres are:

1. It is immune to electrical and magnetic interference.
2. It is highly suitable for harsh industrial environments.
3. It guarantees secure transmission and has a very high transmission capacity.
4. Fiber optic cables can be used for broadband transmission.

Some disadvantages of optical fibres are:

1. Fiber optic cables are quite fragile and may need special care to make them sufficiently robust.
2. Connecting either two fibers together or a light source to a fiber is a difficult process.
3. In order to incept the signal, the fiber must be cut and a detector inserted.
4. Light can reach the receiver out of phase.
5. Connection losses are common problems.
6. They are more difficult to solder.
7. They are the most expensive of all the cables.
