I-fiber optic transceiver iyiyunithi yokuguqula imidiya ye-Ethernet eshintshanisa amasiginali kagesi asontekile amabanga amafushane kanye namasiginali okubona amabanga amade. Ibizwa nangokuthi i-photoelectric converter (I-Fiber Converter) ezindaweni eziningi. Imikhiqizo ivamise ukusetshenziswa endaweni yangempela yenethiwekhi 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. Okufana nokuthi: ukudluliswa kwesithombe sevidiyo enencazelo ephezulu yokuqapha amaphrojekthi okuphepha; ngesikhathi esifanayo, iphinde yadlala indima enkulu ekusizeni ukuxhuma imayela lokugcina lemigqa ye-fiber optic kunethiwekhi yendawo yedolobha elikhulu kanye nenethiwekhi yangaphandle.

I-Fiber optic transceiver tx ne-rx:

Uma usebenzisa ama-transceiver e-fiber optic ukuxhuma amadivaysi ahlukene, kufanele unake izimbobo ezihlukene ezisetshenziswayo.
1. Ukuxhumeka kwe-transceiver ye-fiber optical kumishini ye-100BASE-TX (switch, hub): qinisekisa ukuthi ubude bekhebula elisontekile abudluli amamitha ayi-100;
Xhuma isiphetho esisodwa sepheya esontekile embobeni ye-RJ-45 (imbobo ye-Uplink) ye-fiber optic transceiver, kanye nesinye isiphetho sembobo ye-RJ-45 (imbobo evamile) yedivayisi ye-100BASE-TX (switch, hub).

2. Ukuxhumeka kwe-transceiver ye-fiber optical kumishini ye-100BASE-TX (ikhadi lenethiwekhi): qinisekisa ukuthi ubude bekhebula elisontekile abudluli amamitha angu-100;
Xhuma isiphetho esisodwa sepheya esontekile embobeni ye-RJ-45 (imbobo ye-100BASE-TX) ye-fiber optic transceiver, nesinye isiphetho sembobo ye-RJ-45 yekhadi lenethiwekhi.

3. Ukuxhumeka kwe-fiber optic transceiver ku-100BASE-FX: qinisekisa ukuthi ubude be-fiber abudluli ibanga lebanga elinganikezwa idivayisi;
Ingxenye eyodwa yefiber ixhunywe kusixhumi se-SC/ST se-fiber optic transceiver, kanti enye ixhunywe kusixhumi se-SC/ST sedivayisi ye-100BASE-FX.

Umehluko phakathi kwe-fiber optic transceiver tx ne-rx:
tx iyathumela, i-rx iyamukela. Ku-fiber optical, kukhona ipheya, kanti i-transceiver iyipheya. Ukuthumela nokwamukela kufanele kwenziwe kanyekanye. Kunenkinga uma ukwamukela kuphela kodwa ungathumeli, nokuthumela nokungamukeli kuphela. Uma ukuxhuma kuphumelele, zonke izibani zamandla nezibani zesignali ze-fiber optic transceiver kumele zikhanyise ukuze kuxhumeke.
