Preform Imilinganiselo
Imilinganiselo yepreform iya kuba njengakuLuhlu 1.1 ngezantsi.
Itheyibhile 1.1 Preform Dimensions

| 9 | Preform Non-setyhula | ≤ 1% | |
| 10 | Imposiso yoxinaniso | ≤ 0.5 μm | |
| 11 | Imbonakalo | (Qaphela 1.4&1.5) |
Umfanekiso 1.1 Ubume bePreform
Qaphela 1.4: Amaqamza kummandla wangaphandle wogqume (jonga umfanekiso 1.2) uya kuvunyelwa, kuxhomekeke kubungakanani; inani lamaqamza ngeyunithi nganye yomthamo aliyi kudlula ezi zichazwe kwiTheyibhile 1.2 ngezantsi.
ITheyibhile 1.2 iBubble kwiPreform
Indawo kunye nobungakanani beBubble | Inani / 1,000 cm3 | |
Ummandla ongundoqo (=undoqo + isigqubuthelo sangaphakathi) | (Jonga inqaku 1.5) | |
| INgingqi yoKugquma kwaNgaphandle (=ujongano + isigqubuthelo sangaphandle) | ~ 0.5 mm | Akukho Bala |
0.5 ~ 1.0 mm | ≤ 10 | |
1.0 ~ 1.5 mm | ≤ 2 | |
1.5 ~ 2.0 mm | ≤ 1.0 | |
2.1 mm ~ | (Jonga inqaku 1.5) | |

IiNgcaciso zeFayibha ekujoliswe kuzo
Xa iimeko zokudweba kunye neemeko zokulinganisa zilungile kwaye zizinzile, i-preforms iya kulindeleka ukuba ihlangabezane neenkcukacha zefiber ekujoliswe kuzo njengoko kuboniswe kwiThebhile 2.1.
Uluhlu 2.1 Iimpawu zeFayibha ekujoliswe kuzo
Into | Iimfuno |
| |
1 | Ukunciphisa kwi-1310 nm | ≤ 0.34 dB/km |
|
Ukunciphisa kwi-1383 nm | ≤ 0.34 dB/km | (Qaphela 2.1) | |
Ukunciphisa kwi-1550 nm | ≤ 0.20 dB/km |
| |
Ukunciphisa kwi-1625 nm | ≤ 0.23 dB/km |
| |
Ukufana kokunciphisa | ≤ 0.05 dB/km ku-1310&1550 nm |
| |
2 | I-Mode Field Diameter kwi-1310 nm | 9.1± 0.4 µm |
|
3 | Ubude beCable Cutoff (λcc) | ≤ 1260 nm |
|
4 | I-Zero Dispersion Wavelength (λ0) | 1300 ~ 1324 nm |
|
5 | Ukusasazwa kwi-1285 ~ 1340 nm | -3.8 ~ 3.5 ps/(nm·km) |
