Ransceivers vs. Transponders: Gịnị bụ ihe dị iche?

N'ozuzu, transceiver bụ ngwaọrụ nke nwere ike izipu ma nata akara ngosi, ebe transponder bụ akụkụ nke ihe nhazi ya bụ nke e mere ka ọ nyochaa akara ngosi ndị na-abata ma nwee azịza ndị edobere na netwọk nkwukọrịta fiber-optic. N'ezie, a na-ahụkarị transponders site na ọnụego data ha na oke anya nke akara ngosi nwere ike ịga. Transceivers na transponders dị iche ma enweghị ike ịgbanwe agbanwe. Isiokwu a na-akọwa ihe dị iche n'etiti transceivers na repeaters.

Ndị na-ebufe ihe na transceivers vs. Ndị na-ebufe ihe: Nkọwa

N'ihe gbasara nkwukọrịta eriri optic, e mere transceivers anya ka ha na-ebufe ma nata akara ngosi anya. Modulu transceiver a na-ejikarị eme ihe bụ ngwaọrụ I/O (ntinye/mmepụta) a na-agbanwe agbanwe nke ọma, nke a na-etinye na ngwaọrụ netwọk, dị ka switches netwọk, sava, na ihe ndị yiri ya. A na-ejikarị transceivers anya eme ihe na ebe data, netwọk ụlọ ọrụ, kọmputa igwe ojii, sistemụ netwọk FTTX. E nwere ọtụtụ ụdị transceivers, gụnyere 1G SFP, 10G SFP+, 25G SFP28, 40G QSFP+, 100G QSFP28, 200G na ọbụna transceivers 400G. Enwere ike iji ha na ọtụtụ eriri ma ọ bụ eriri ọla kọpa maka nnyefe anya na netwọk dị mkpụmkpụ ma ọ bụ ogologo. Na mgbakwunye, enwere transceivers eriri optic BiDi nke na-enye modulu ohere izipu ma nata data n'elu otu eriri iji mee ka sistemụ cabling dị mfe, mụbaa ikike netwọk, ma belata ọnụ ahịa. Na mgbakwunye, modulu CWDM na DWDM nke na-agbakwụnye ogologo ebili mmiri dị iche iche na otu eriri dabara adaba maka nnyefe anya na netwọk WDM/OTN.

Ọdịiche dị n'etiti Transceiver na Transponder

Ma ndị na-emegharị ihe na ndị na-agbanwe ihe bụ ngwaọrụ yiri nke ha nke na-agbanwe akara eletriki dum-duplex ka ọ bụrụ akara optical full-duplex. Ihe dị iche n'etiti ha bụ na ndị na-emegharị ihe na eriri optical na-eji njikọ usoro, nke nwere ike izipu ma nata akara n'otu modulu ahụ, ebe ndị na-emegharị ihe na-eji njikọ parallel, nke chọrọ modulu eriri optical abụọ iji nweta nnyefe niile. Ya bụ, ndị na-emegharị ihe kwesịrị izipu akara site na modulu n'otu akụkụ, modulu dị n'akụkụ nke ọzọ na-aza akara ahụ.

Ọ bụ ezie na transponder nwere ike ijikwa akara ngosi dị ala karịa nke transceiver, ọ nwere nnukwu nha na ike dị elu karịa transceiver. Na mgbakwunye, modulu anya nwere ike inye naanị mgbanwe eletriki-na-optical, ebe transponders nwere ike nweta mgbanwe eletriki-na-optical site na otu wavelength gaa na nke ọzọ. Ya mere, enwere ike iche na transponders dị ka transceivers abụọ etinyere azụ-na-azụ, nke nwere ike iji maka nnyefe anya dị anya na sistemụ WDM nke transceivers anya nkịtị na-apụghị iru.

Na mmechi, transceivers na transponders dị iche na ọrụ na ojiji. Enwere ike iji eriri repeaters gbanwee ụdị mgbaama dị iche iche, gụnyere multimode gaa na otu mode, eriri abụọ gaa na otu eriri, na otu wavelength gaa na wavelength ọzọ. Transceivers, nke nwere ike ịtụgharị naanị akara eletriki ka ọ bụrụ akara anya, ejirila ya ogologo oge na sava, switches netwọk ụlọ ọrụ, na netwọk ebe data.
