Uru nke eriri optic transceivers
Enwere ọtụtụ uru iji transceiver fiber optic. Dịka ọmụmaatụ, ndị transceivers fiber optic nwere ike ịgbatị ebe nnyefe Ethernet na ịgbatị radius mkpuchi Ethernet.Fiber optic transceivers nwere ike ịtụgharị n'etiti 10M, 100M ma ọ bụ 1000M Ethernet eletriki na ngwa anya.

Kedu ka esi amata ọdịiche dị n'etiti transceivers otu-fiber na dual-fiber transceivers?
Mgbe transceiver anya na-agbanye n'ime ihe ntanetị anya, a na-ekewa transceiver anya n'ime otu-fiber transceiver na onye na-eme ihe abụọ dị ka ọnụ ọgụgụ nke cores nke ndị na-agba ọsọ ngwa ngwa. transceiver otu-fiber bụ isi, nke na-ahụ maka ịnyefe data na ịnata data.Fiber jumper ejikọrọ na transceiver dual-fiber transceiver nwere cores abụọ, otu n'ime ha na-ahụ maka ịnyefe data na nke ọzọ na-ahụ maka ịnata data. onye na-ahụ maka ihe na-ahụ anya adịghị enwe modul ngwa anya agbakwunyere, ọ dị mkpa ịmata ọdịiche dị na ọ bụ otu-fiber transceiver ma ọ bụ eriri abụọ-fiber dị ka ihe ntinye anya. ya bụ, mgbe interface ahụ bụ ụdị simplex, transceiver optical bụ transceiver otu-fiber. Mgbe a na-etinye transceiver fiber-optic n'ime modul-fiber bidirectional optical modul, ya bụ, interface bụ nke ụdị duplex, na transceiver bụ transceiver dual-fiber.
