Nkuko tubizi, transceiver isanzwe ya SFP isanzwe ifite ibyambu bibiri, kimwe nicyambu cya TX gikoreshwa mugutanga ibimenyetso, ikindi nicyambu cya RX gikoreshwa mukwakira ibimenyetso.Bitandukanye na transfert ya SFP isanzwe, TransDiver ya BiDi SFP iri hamwe nicyambu kimwe gusa ikoresha icyuma cya WDM cyohereza no kwakira ibimenyetso hejuru ya fibre imwe.Mubyukuri, compact ya SFP ni umuyoboro wa BiDi SFP 2, uhuza BiDi SFP ebyiri muburyo bumwe bwa SFP.Kubwibyo, SFP yoroheje nayo iri hamwe nibyambu bibiri nkibisanzwe SFP.

SFP, BiDi SFP hamwe nuburyo bworoshye bwo guhuza SFP
ByoseSFPigomba gukoreshwa muri babiri.Kuri SFP zisanzwe, tugomba guhuza SFP ebyiri zifite uburebure bumwe hamwe.Kurugero, dukoresha 850nm SFP kumpera imwe, noneho tugomba gukoresha 850nm SFP kurundi ruhande (yerekanwe kumashusho hepfo).

KuriBiDi SFP, kubera ko yohereza kandi yakira ibimenyetso bifite uburebure butandukanye, tugomba guhuza BiDi SFPs ebyiri zifite uburebure butandukanye hamwe.Kurugero, dukoresha 1310nm-TX / 1490nm-RX BiDi SFP kuruhande rumwe, noneho tugomba gukoresha 1490nm-TX / 1310nm-RX BiDi SFP kurundi ruhande.
Ububiko bwa SFP (GLC-2BX-D) mubisanzwe ikoresha 1490nm kugirango yohereze ibimenyetso na 1310nm kugirango yakire ibimenyetso.Kubwibyo, compact ya SFP ihora ihujwe na 1310nm-TX / 1490nm-RX BiDi SFP hejuru ya fibre ebyiri imwe.

BiDi SFP hamwe na Porogaramu ya SFP
Kugeza ubu, BiDi SFP ikoreshwa cyane muri FTTx yoherejwe P2P (point-to-point).Umuyoboro wa FTTH / FTTB ukora Ethernet igizwe nibiro bikuru (CO) bihuza ibikoresho byabakiriya (CPE).Imiyoboro ikora ya Ethernet ikoresha P2P yububiko aho buri mukiriya wanyuma ahujwe na CO kuri fibre yabugenewe.BiDi SFP yemerera itumanaho ryibice bibiri kuri fibre imwe ukoresheje umurongo wa multiplexing (WDM), bigatuma CO na CPE bihuza byoroshye.Gucunga SFP byongera cyane ubwinshi bwicyambu cya CO muguhuza fibre ebyiri ya fibre imwe mubintu bya SFP.Mubyongeyeho, compact SFP izagabanya cyane gukoresha ingufu muri rusange kuruhande rwa CO.

JHA-Tech BiDi hamwe na SFP Yoroheje
JHA-Tech itanga BiDi zitandukanye za SFP.Barashobora gushyigikira igipimo cyamakuru atandukanye kandi bagashyigikira intera ikwirakwizwa kugera kuri kilometero 120 zishobora kuzuza ibisabwa na serivisi ya fibre uyumunsi kubatwara ninganda.
