I-Optical fiber transceiver iyisixhobo esiguquguqukayo nesisebenzayo sokuguqula i-photoelectric edlala indima ebalulekileyo kwi-multi-protocol photoelectric hybrid LAN. Ngoku, ukuze ufumane ngcono kwaye uphelise iimpazamo zekhonkco, ezinye ii-transceivers zefiber optical zinekhonkco zingaphumeleli (LFP) kunye ne-remote fault (FEF) imisebenzi ye-alamu.
Ngaphambi kokuba siqale ukuchaza ukungaphumeleli kwekhonkco phezu (LFP) kunye nokungaphumeleli okude (FEF) imisebenzi ye-alarm ye-fiber transceivers, kuyimfuneko ukuqonda indima ye-fiber transceivers kwinethiwekhi yendawo yendawo.
I-Optical fiber transceiver inamazibuko ombane kunye ne-optical, adla ngokusetyenziswa ukudibanisa iiswitshi ze-optical port kunye nokutshintsha kombane ukuqaphela uguqulo lwe-photoelectric phakathi kwezixhobo ezibini, njengoko kubonisiwe kulo mfanekiso ungezantsi:
Ngokuqinisekileyo, umsebenzi oyintloko we-fiber optical transceiver kukuguqula ukukhanya kumbane, njengebhuloho phakathi kwezixhobo ezibini ezingakwazi ukuthetha ngokuthe ngqo, kodwa indima yayo ingaphezulu kakhulu.
Xa i-fiber transceiver isetyenziswe ngababini, iintambo ezisetyenzisiweyo ziquka ubuncinane iintambo ezimbini ze-fiber optic kunye neentambo ezimbini (njengoko kuboniswe ngezantsi). Yinto entsonkothileyo yale cabling ekhokelela kwi-failover yekhonkco (LFP) kunye ne-distal fault (FEF) imisebenzi ye-alarm ye-fiber transceiver.
I-Failover yekhonkco (LFP) ibhekisa kwizixhobo ezibini zonxibelelwano ezinxibelelanayo (iitransceivers, iiswitshi,iirothanjl.). Enye (ekufuphi ekupheleni) ine-Fault yekhonkco, kwaye impazamo yekhonkco inokudluliselwa kwenye (ekude) isixhobo. Ngokomzekelo, ii-transceivers ezimbini ze-fiber optical A kunye ne-B zine-A fault ye-link kwi-port yombane ye-transceiver A, kwaye i-transceiver iya kudlulisela impazamo yombane kwi-port optical. I-transceiver iya kuyeka ukuthumela idatha kwi-optical port; Ukuba i-transceiver ekupheleni kwe-B ayiphumelelanga ukufumana idatha kwi-transceiver ekupheleni kwe-A, iyazi ukuba i-transceiver ekupheleni kwe-A inokusilela kwekhonkco, kwaye i-transceiver ekupheleni kwe-B iyeka ukuthumela idatha kwi-optical kunye ne-electrical ports. I-alamu ye-Failure Over (LFP) yekhonkco yenza ukuba abalawuli benethiwekhi bazi ngokukhawuleza kwaye baphathe iimpazamo zenethiwekhi kunye nokunciphisa ilahleko ebangelwa yimpazamo yenethiwekhi.
Ukungaphumeleli okukude (FEF) kubhekiselele ekungaphumelelini kwentambo ye-optical ethumela idatha kwi-fiber optic transceiver A ukuya kwi-fiber optic transceiver B, kunye ne-optical port ye-fiber optic transceiver A iyeka ukuthumela idatha kwi-port optical ye-fiber optic transceiver B. Ukuba enye ikhebula isebenza ngokufanelekileyo, i-port optical ye-transceiver ye-B iyaqhubeka nokuthumela idatha kwi-port optical ye-A transceiver, ebangela ukuhluleka kwenethiwekhi. Indima ye-alamu ye-Alarm Failure (FEF) kukubonisa le ngxaki.
Oku ngasentla yinkcazo ye-transceiver LFP kunye nemisebenzi ye-FEF eziswa yi-Shenzhen HDV Phoelectron Technology Co., LTD. Izixhobo zethu zenethiwekhi ezinxulumene nazoI-ONUuthotho,OLTuthotho, uthotho lweemodyuli zokubona, wamkelekile kuthethwano olungaphaya.
