Maqaalkan waxaan kaga hadlayaa waxa sababa luminta gudbinta fiber optics-ka.Aan barano…
Sababta uu fiber-ka indhaha u beddelo gudbinta dhexe iyo fogaanta fog ee fiilooyinka shabakadda waa sababta oo ah gudbinta fiber-ka indhaha ayaa leh khasaare yar, khasaaraheeduna waxa loo qaybiyaa kuwan soo socda:
Khasaaruhu waa luminta tamarta iftiinka ee ay keento nuugista, kala firdhinta iyo daadinta dhexdhexaadka (hawada) marka iftiinka lagu kala qaado fiber-ka indhaha (filibka indhaha si buuxda uma go'doomi karo iftiinka, taas oo u horseedi doonta iftiinka iftiinka).Luminta qaybtan tamarta waxay kordhisaa fogaanta gudbinta.Korodhka ayaa lagu kala firdhiyaa heer go'an.
Tusaale ahaan: 1310nm moduleka indhaha wuxuu xisaabiyaa khasaaraha gudbinta isku xirka 0.35dBm/km,
Qalabka indhaha ee 1550nm wuxuu xisaabiyaa khasaaraha gudbinta isku xirka 0.20dBm/km.Iyo khasaarahan ayaa sidoo kale saameyn doona heerar kala duwan, iyo luminta gudbinta isku xirka waxay u dhigantaa heerka.
Kala firdhinta waxa inta badan sababa in hirarka korantada ee hirarka dhaadheer ee kala duwan ay ku socdaan isla dhex dhexaad iyaga oo xawli kala duwan ku socda, taas oo keenta in qaybaha kala duwan ee hirarka ishaadu ay soo gaadho dhamaadka wakhtiga wakhtiyo kala duwan taas oo ay ugu wacan tahay isu-ururinta fogaanta gudbinta, taas oo keenta garaaca garaaca wadnaha. ballaarinta iyo awood la'aanta in la kala saaro calaamadda.qiimaha.Xisaabinta qiimaha firidhsan waa mid aad u adag oo guud ahaan waa tixraac kaliya.
Luminta gelinta, ilaa inta interface-ku uu ku dhammaanayo fiber-ka indhaha la dabar-goynayo, aan si buuxda loo shaabadeynin, taas oo keeneysa daadinta iftiinka iyo ifafaale kale, taasoo keentay luminta galintan.Guud ahaan, lumintu waa inta u dhaxaysa 0.15-0.35dbm.
Kor ku xusan waa sharaxaad ka mid ah aqoonta luminta gudbinta fiber indhaha oo ay keentay Shenzhen HDV photoelectric Technology Co., Ltd. The alaabta module soo saaray cover shirkadda modules fiber indhaha, modules Ethernet, modules transceiver fiber indhaha, modules helitaanka fiber indhaha, SSFP modules indhahaiyoFiber indhaha ee SFP, iwm. Alaabooyinka cutubka sare waxa ay ku siin karaan taageero xaalado shabakadeed oo kala duwan.Kooxda R & D ee xirfadlayaasha ah iyo xoogga leh waxay ka caawin karaan macaamiisha arrimaha farsamada, iyo koox ganacsi oo feker iyo xirfad leh ayaa ka caawin kara macaamiisha inay helaan adeegyo tayo sare leh inta lagu jiro la-talinta kahor iyo shaqada soo-saarka kadib.Ku soo dhawoow nala soo xiriir nooc kasta oo weydiin.
