Hotline Telephone Over Fiber Optics
Hotline Telephone Setup
The hotline analog telephone is setup by using a pair of subscriber side modems at both ends over a fiber optics link.
The fiber optics link could be either be SM or MM with a possible distance of up to 20 - 30 km depending upon modem specification.
How Does Hotline Telephone Works?
Simply just lift up the analog handset at one end , the analog phone located on the other end will automatically give a ring without the need to do any dialing.
I have been in the field of fiber optics since early 1990s. I gained fiber optics skills and knowledge via my working experience as end-user, main contractor and sub-contractor and finally as an optical fiber enterpreneur.
