Abstract

"PROCESSO DE PREPARAçãO DE UMA PRé-FORMA DE FIBRA óPTICA". Pó de vidro (130) é depositado sobre um bastão de vidro por um queimador (140). O corpo é estirado (126). Mais deposição e estiramento são efetuados. O corpo final é então estirado em uma fibra."PROCESS FOR PREPARING AN OPTICAL FIBER FORM". Glass dust (130) is deposited on a glass rod by a burner (140). The body is stretched (126). Further deposition and stretching are effected. The final body is then stretched into a fiber.
