One lead connects the board to electronics which in turn feeds a light emitting diode connected to an orange plastic insulated glass fiber. Printed on board: "G.T.E. Laboratories / C.O. Light Source Mod". Dymo label reads: "TLS". Using this equipment, GTE opened a fiber-optic telephone line between Long Beach and Artesia, California, in 1977. The transmitter employed a light-emitting diode (LED). Later systems would use lasers." Reference: http://www.sil.si.edu/Exhibitions/Underwater-web/uw-optic-05.htm.
