Ndezvipi zvinhu zvine hunhu hwe single-mode fiber?

Hunhu hwe Faibha yemhando imwe cheteGwaro rakakwana

Fiber yemhando imwe chete (SMF) imhando yefiber ye optical yakagadzirirwa kutakura chiedza zvakananga kuburikidza nefiber pasina kurasikirwa kwakanyanya. Inoshandiswa zvakanyanya mukutaurirana nefoni uye networking nekuda kwekushanda kwayo kwepamusoro-soro padaro refu. Pano, tinoongorora hunhu hukuru hunoita kuti SMF ishande zvakanaka. faibha yemhando imwe chete ive sarudzo inosarudzwa yekutumira data nekukurumidza.

1. Dhayamita yepakati:
Fiber yemhando imwe chete ine dhayamita diki yepakati, inowanzoita ma micrometer 8 kusvika 10. Iyi core diki inobvumira nzira imwe chete yechiedza kupararira, zvichideredza zvakanyanya kupararira kwemodal uye zvichiita kuti data ritapurirwe kure kure pasina kuora.DACiyoni.

2. Kusanyanya kurerutsa zvinhu:
Chimwe chezvinhu zvakakosha zve single-mode fiber ndechekuti ine attenuation rate yakaderera. Attenuation inoreva kurasikirwa nesimba rechiratidzo painofamba nefiber. Single-mode fibers dzine attenuation rates yakaderera se0.2 dB/km, zvichiita kuti dzive dzakanakira masisitimu ekutaurirana ari kure.

3. Bhendi repamusoro:
Mafiber emhando imwe chete anopa kugona kwakanyanya kwebandwidth. Izvi zvinoreva kuti anogona kutsigira data rakawanda zvichienzaniswa nemafiber emhando dzakasiyana. Bandwidth yakakura yakakosha kumapurogiramu anoda kutumira data rakawanda, senge internet backbones nenzvimbo dzedata.

4. Kutapurirana kure:
Nekuda kwekusasimba kwadzo uye bandwidth yakakwira, mafiber emodhi imwe chete akanakira kutumira masaini kure. Anogona kutumira masaini kure nemakiromita anopfuura zana pasina kudiwa kwema amplifiers esignal kana ma repeater, zvichiita kuti ave anobatsira pakuisa network yakakura.

5. Kuenderana kwehurefu hwemafungu:
Mafayibha emhando imwe chete anowirirana nemhando dzakasiyana dzemarefu emwenje, anowanzo shanda mumahwindo e1310 nm ne1550 nm. Marefu aya haanyanyi kurasikirwa kana kupararira, zvichiwedzera kuvandudza kushanda zvakanaka kwefayibha.

6. Kukanganisa kushoma:
Fiber dzemhando imwe chete hadzinyanyi kukanganiswa nekunze, zvakaita se electromagnetic interference (EMI) uye radio frequency interference (RFI). Izvi zvinoita kuti chiratidzo chive chakachena uye chakavimbika, izvo zvakakosha pakushandisa kutaurirana kwakakosha.
