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.
