After completion of the 1873 cable (see above), because of the shorter route, 1000 nm of cable was left and so additional cable was ordered to enable another cable to be laid, this being done in 1874. The specifications for this cable are thus identical to those of the 1873 cable. | |

In 1952 Monarch (4) undertook major repair work on this cable. and a note in the Telcon magazine (Issue 21, Autumn 1953) reports that the entire length of this cable was currently being replaced, also by Monarch (4). The core of the 1525nm of replacement cable was insulated with Telcothene, making it “the first transatlantic cable to be entirely insulated with that plastic material”. As part of this work, the cable was also diverted from Harbour Grace into St. John's. |
