Submarine Optical Cable EMOS-1

Submarine optical cable connecting Israel (Tel Aviv) to Turkey (Marmaris), Greece (Lechaina) and Italy (Palermo), named EMOS (East Mediterranean Optical System). Overall length of 3,100 km.

Six optical fibers in protective U-shaped groove plastic skeleton, surrounded by layers of high-strength steel wires  and a copper layer, covered by a polycarbonate insulation jacket, built to withstand the harsh marine environment.

Each fiber pair was used for 140 MB/s PDH (Plesiochronous Digital Hierarchy) digital transmission, providing 1,920 PCM (Pulse Code Modulation) 64 kB/s voice channels.

The cable was laid on the seabed, with repeaters in metal containers, receiving DC feed through the cable.

The cable was owned by an international consortium led by Bezeq, Israel, with 16 administrations and telecom operators from 11 countries, and was inaugurated in May 1991.

EMOS was the first Mediterranean optical submarine cable, and the main submarine cable connecting Israel to the world until the inauguration of the LEV cable in 1999.
