Dị ka akụkụ dị mkpa nke nnyefe netwọk anya, modul optical fiber modul na-arụ ọrụ dị ka ntụgharị fotoelectric, nke mere na enwere ike ibunye akara na eriri anya. Ya mere, ị maara ka ịmata ọdịiche ma ihengwa anya eriri modul bụ otu-modema ọ bụ multi-mode? Nke a bụ ụzọ ole na ole ị ga-esi mata ọdịiche dị n'etiti modul eriri multi-mode na modul eriri otu ụdị.
Mbụ, anyị nwere ike ile anya na wavelength parameters nke ngwa anya eriri modul. N'ozuzu, ogologo wavelength nke ngwa anya eriri modul bụ 850nm, na ngwa anya eriri modul bụ a multimode ngwa anya eriri modul. The wavelength nke otu-mode ngwa anya eriri modul bụ n'ozuzu 1310nm, 1330nm, 1490nm, 1550nm, wdg Na mgbakwunye, na CWDM agba ìhè modul na DWDM agba ìhè modul bụ ma otu-mode eriri modul.
Nke abụọ, anyị nwere ike ile anya na nnyefe anya nke eriri optic modul. Ebe dị anya nke multimode fiber optic modul bụ ihe na-erughị 2km, nke kwesịrị iji multimode fiber jumpers mee ihe. Ogologo nnyefe nke modul optical optical modem na-adịkarị karịa 2km, otu Gigabit single mode optical fiber modul nwere ike ibunye ruo 160km, na 10-Gigabit otu mode fiber optical module nwere ike ibunye ruo 100km.
Nke atọ, anyị nwere ike ileba anya na ụdị ngwa anya akụrụngwa nke eriri optic modul. Ngwaọrụ na-ebunye ọkụ nke multimode fiber optic module bụ VCSEL, na ngwaọrụ na-ebunye ọkụ nke otu mode fiber optic module bụ DFB, EML, FP, wdg.
Nke anọ, anyị nwere ike ikpe otu-mode ma ọ bụ multi-mode si na agba nke sere mgbanaka nke eriri optic modul. Agba nke ndọta mgbanaka nke multimode fiber optic modul na nnyefe ọnụego na-erughị 40G (ewezuga 40G) bụ n'ozuzu oji, 40G na n'elu (gụnyere 40G) Agba nke ịdọrọ mgbanaka nke multimode fiber optic modul bụ beige. Mgbanaka mgbanaka nke modul eriri otu ụdị nwere ogologo ogologo nke 1310nm bụ acha anụnụ anụnụ. Na mgbakwunye, enwere agba ndị ọzọ nke mgbanaka ịdọrọ. Ha niile bụ otu mode fiber modul.
Ịmara ụdị eriri (otu-ụdị/multi-mode) nke eriri optic modul na-enyere anyị aka ịhọrọ eriri jumper kwekọrọ n'ụzọ ziri ezi.
