Manufacture

With a rich heritage of development and manufacturing dating back to 1842, SubCom's legacy of building communications systems today extends over three centuries. From its early beginning in the manufacture of the first undersea telegraph cable, our Newington, New Hampshire facility has evolved into a modern-day producer of some of the world's most advanced undersea fiber optic cable and repeater telecommunications systems installed around the globe by a fleet of world-class cable ships.

SubCom manufactures both Wet Plant (cable, repeaters, and branching units) and Dry Plant (transmission, powering, and monitoring equipment) in the United States. SubCom's talented employees and management team including it's research and development laboratories, manufacturing facilities, ships, and depots have produced over 490,000 kilometers of undersea cable in over 100 undersea fiber optic systems that are serving worldwide communications needs. That is enough cable to circle the earth over 12 times at the equator.

SubCom has been integrally involved in the manufacturing of transmission equipment (dry plant) since the inception of the undersea fiber optic industry. Currently SubCom manufactures its most powerful and reliable generation of equipment in Newington, New Hampshire.

The quantity of current generation equipment manufactured is the technological equivalent of transmitting over 200 full-length DVDs simultaneously in 1 second. Both of the SubCom's facilities are ISO 9001:2008 Certified.
