Emkhakheni wamanethiwekhi okuxhumana, sivamise ukusebenzisa ama-transceiver e-fiber optic neziguquli zephrothokholi, kodwa abangani abangazi okuningi ngazo bangase bakudide lokhu kokubili. Ngakho-ke, uyini umehluko phakathi kwama-transceivers e-fiber optic nama-converter ephrothokholi?

Umqondo wama-fiber optic transceivers:
I-Fiber optic transceiver iyiyunithi yokuguqula imidiya ye-Ethernet eshintshanisa amasiginali kagesi asontekile amabanga amade kanye namasiginali okubona amabanga amade. Ibizwa nangokuthi i-photoelectric converter (FiberConverter) ezindaweni eziningi. Imikhiqizo ngokuvamile isetshenziswa ezindaweni zangempela zenethiwekhi lapho izintambo ze-Ethernet zingakwazi ukumbozwa khona futhi imicu yokubona kufanele isetshenziselwe ukunweba ibanga lokudlulisela, futhi ngokuvamile ibekwe kuhlelo lokusebenza lwesendlalelo sokufinyelela samanethiwekhi endawo yedolobha elikhulu; njengokuthi: ukuhanjiswa kwesithombe sevidiyo enencazelo ephezulu kumaphrojekthi okuphepha okugadwa; Iphinde yadlala indima enkulu ekusizeni ukuxhuma imayela lokugcina lemigqa ye-fiber optic kunethiwekhi yendawo yedolobha elikhulu kanye nenethiwekhi yangaphandle.

Umqondo wokuguqula iphrothokholi:
Isiguquli sephrothokholi sifushanisiwe ngokuthi i-co-transfer, noma i-interface converter, eyenza abasingathi kunethiwekhi yokuxhumana abasebenzisa amaphrothokholi ahlukene wezinga eliphezulu ukuthi basasebenzisane ukuze baqedele izinhlelo zokusebenza ezihlukahlukene ezisabalalisiwe. Isebenza kungqimba yezokuthutha noma ngaphezulu. Isiguquli sephrothokholi esibonakalayo ngokuvamile singaqedwa nge-chip ye-ASIC, enezindleko eziphansi nosayizi omncane. Ingakwazi ukuguqula phakathi kwe-Ethernet noma i-V.35 data interface yephrothokholi ye-IEEE802.3 kanye nesixhumi esibonakalayo esingu-2M sephrothokholi evamile ye-G.703. Ingase futhi iguqulwe phakathi kwe-serial port engu-232/485/422 kanye ne-E1, i-CAN interface ne-2M interface.

Isifinyezo: Ama-transceivers e-Fiber optic asetshenziselwa kuphela ukuguqulwa kwesignali ye-photoelectric, kuyilapho iziguquli zephrothokholi zisetshenziselwa ukuguqula iphrothokholi eyodwa kwenye. I-transceiver ye-fiber optical iyithuluzi lesendlalelo somzimba, eliguqula i-fiber optical ibe yibhangqa elisontekile, ngokuguqulwa kwe-10/100/1000M; kunezinhlobo eziningi zeziguquli zephrothokholi, iningi lazo okungamadivayisi anezendlalelo ezi-2.
