Monga tikudziwira, transceiver wamba wa SFP nthawi zambiri amakhala ndi madoko awiri, limodzi ndi doko la TX lomwe limagwiritsidwa ntchito potumiza chizindikiro, ndipo linalo ndi doko la RX lomwe limagwiritsidwa ntchito polandila zikwangwani.Mosiyana ndi transceiver wamba wa SFP, transceiver ya BiDi SFP ili ndi doko limodzi lokha lomwe limagwiritsa ntchito cholumikizira cha WDM chothandizira kutumiza ndikulandila ma siginecha pa chingwe chimodzi.Ndipotu, compact SFP ndi 2-channel BiDi SFP, yomwe imagwirizanitsa awiri a BiDi SFP mu gawo limodzi la SFP.Chifukwa chake, SFP yaying'ono ilinso ndi madoko awiri monga SFP wamba.

SFP, BiDi SFP ndi Njira Zolumikizirana za Compact SFP
ZonseMa transceivers a SFPziyenera kugwiritsidwa ntchito pawiri.Kwa ma SFP wamba, tiyenera kulumikiza ma SFP awiri omwe ali ndi kutalika kofanana pamodzi.Mwachitsanzo, timagwiritsa ntchito 850nm SFP pamapeto amodzi, ndiye tiyenera kugwiritsa ntchito 850nm SFP kumbali inayo (yomwe ili pansipa).

ZaBiDi SFP, popeza imatumiza ndi kulandira zizindikiro ndi mafunde osiyanasiyana, tiyenera kugwirizanitsa ma SFP awiri a BiDi omwe ali ndi kutalika kosiyana.Mwachitsanzo, timagwiritsa ntchito 1310nm-TX/1490nm-RX BiDi SFP pamapeto amodzi, ndiye tiyenera kugwiritsa ntchito 1490nm-TX/1310nm-RX BiDi SFP kumbali ina.
compact SFP (Chithunzi cha GLC-2BX-D) nthawi zambiri amagwiritsa ntchito 1490nm kutumiza chizindikiro ndi 1310nm kulandira chizindikiro.Chifukwa chake, compact SFP nthawi zonse imalumikizidwa ndi 1310nm-TX/1490nm-RX BiDi SFP pamitundu iwiri yamtundu umodzi.

BiDi SFP ndi Compact SFP Applications
Pakalipano, BiDi SFP imagwiritsidwa ntchito kwambiri mu FTTx kutumiza P2P (point-to-point) kugwirizana.Netiweki ya FTTH/FTTB yogwira Efaneti imakhala ndi ofesi yapakati (CO) yolumikizana ndi zida zamakasitomala (CPE).Maukonde a Active Ethernet amagwiritsa ntchito zomangamanga za P2P momwe kasitomala aliyense amalumikizidwa ndi CO pa fiber yodzipereka.BiDi SFP imalola kulumikizana kwapawiri pa chingwe chimodzi pogwiritsa ntchito wavelength multiplexing (WDM), zomwe zimapangitsa kulumikizana kwa CO ndi CPE kukhala kosavuta.Compact SFP imachulukitsa kuchuluka kwa doko la CO pophatikiza ma transceivers awiri amtundu umodzi kukhala chinthu chimodzi cha SFP.Kuphatikiza apo, compact SFP idzachepetsa kwambiri kugwiritsa ntchito mphamvu zonse kumbali ya CO.

JHA-Tech BiDi ndi Compact SFP Sloutions
JHA-Tech imapereka ma BiDi SFP osiyanasiyana.Atha kuthandizira kusiyanasiyana kwa data ndikuthandizira kufalikira kwa mtunda wopitilira 120 km womwe ungakwaniritse zofunikira zantchito zama fiber zamasiku ano zonyamula ndi mabizinesi.
