1. Muuqaal kala duwan:
Module fiber Optical Module: Waxaa jira laba saldhig oo fiber optic ah, siday u kala horreeyaan, soo dirida (TX) iyo helitaanka (RX) dekedaha indhaha. Waxaa loo baahan yahay in la geliyo laba fiilood oo indhaha ah, iyo dekeddo kala duwan oo indhaha ah iyo fiilooyinka indhaha ayaa loo adeegsadaa gudbinta iyo soo-dhoweynta; Marka la isticmaalo modules-ka laba-geesoodka ah ee fiber-ka, mawjadaha dhererka ee modules-yada labada daraf waa inay noqdaan kuwo joogto ah.
Halbeegga fiber optic module: waxaa jira hal god oo fiber indhaha ah, kaas oo la wadaago dirista iyo helitaanka. Hal fiber optic ah ayaa loo baahan yahay in la geliyo, isla dekedda indhaha iyo gudbinta fiber indhaha ayaa loo isticmaalaa helitaanka iyo dirida; Marka la isticmaalayo hal module fiber optical, mawjadaha dhererka ee modules indhaha ee labada daraf waa in ay iswaafajiyaan, taas oo ah, TX/RX waa ka soo horjeeda.
2. Mawjadaha dhaadheer ee caadiga ah ee kala duwan: moduleka kaliya ee fiber-ku wuxuu leeyahay laba mawjadood oo kala duwan oo loogu talagalay dirida iyo soo-dhowaynta, halka moduleka fiber-ka ah uu leeyahay hal hirar oo keliya;
Mawjada dhererka caadiga ah ee fiber double: 850nm 1310nm 1550nm
Mawjadaha dhererka caadiga ah ee hal fiber inta badan waxaa ka mid ah kuwan soo socda:
Hal fiber oo Gigabit ah:
TX1310/RX1550nm
TX1550/RX1310nm
TX1490/RX1550nm
TX1550/RX1490nm
TX1310nm/Rx1490nm
TX1490nm/Rx1310nm
10 Gigabit hal fiber ah:
TX1270nm/RX1330nm
TX1330nm/RX1270nm
TX1490nm/RX1550nm
TX1550nm/RX1490nm
3. Xawaaraha kala duwan: marka la barbardhigo moduleka laba-geesoodka ah ee fiber-ka, moduleka hal-abuurka ah ee fiber-ka ah wuxuu leeyahay codsiyo ballaaran oo ah 100 megabit, gigabit iyo 10 gigabit; Waa dhif 40G iyo 100G gudbinta xawliga sare leh.
