Used to secure fiber optic cable to a LED on a terminal light source, or a photodiode on a terminal light amplifier in an optical repeater (1982.0529.03 and .04). A metal block with a V-shaped grove running lengthwise. Grove is covered by two metal and one ceramic plates. Threaded mounting holes are underneath. No extant makers marks.
Used in fiber optic repeater (1982.0529.01). A GTE optical repeater set on a circuit board. Seven leads connect the board to the unit which in turn feeds an orange plastic insulated glass fiber. One label reads: "Property of GTE / 47-3T1-034 / Laboratories", second label reads: "Property of GTE / 111-374 / Laboratories". Dymo label reads: "TLA". 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.

Fiber optic cable sample. Used with fiber optics system that includes repeater (1982.0529.01). No extant makers marks. Plastic insulated glass fibers running parallel with an insulated copper line. Internal insulation includes paper and plastic wraps. A foil wrap separates layers within the cable.
Light emitting diode (LED) in a metal canister. Coaxial connector on one end, plastic covered tip on other. Written on canister: "C9". Used on terminal light source board for fiber optics repeater (1982.0529.04)
Photodiode detector in a metal canister. Three leads on one end, plastic covered tip on other. No extant makers markings. Used on terminal light amplifier board for fiber optics repeater (1982.0529.03).
This basket was bought in Luquillo in 1979. The hanging supports are made of bejuco, processed fiber from the century plant, or maguey. A large metal disk was placed around the top to keep rodents from crawling into it from above. Widely used in rural kitchens, it is called a canestillo in the center of the island and a barandillo in the north.
Description (Spanish)
Esta canasta colgante fue adquirida en Luquillo en 1979. Los soportes están hechos de bejuco, fibra procesada del maguey. Se colocó un disco de metal grande alrededor de la parte superior para evitar que se introdujeran los roedores. Se utiliza mucho en las cocinas rurales y se la conoce como canestillo en el centro de la isla y como barandillo en el norte.
