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 modernday 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 two facilities in the United States. In addition, SubCom maintains a strategic supply relationship for cable manufacturing with Hitachi Cable Ltd. in Japan. SubCom and its partner have manufactured more than 420,000 km of undersea cable, which is enough cable to wrap around the globe more than ten times.

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 their most powerful and reliable generation of equipment in Lowell, Massachusetts.

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 / 2000 Certified. The Lowell facility is also ISO 14001 Certified.
