Zotumizira pafupi ndi malo ocheperako, makonde opatsirana, kapena m’zigawo za mphezi, tchulani kwathunthu sanali zitsulo (FRP kapena KFRP) zosiyana.

Kodi chodzithandizira FTTH dontho chingwe?

Chingwe chodzithandizira chokha chimakhala ndi chinthu chophatikizika cha messenger - nthawi zambiri waya wachitsulo mu GJYXCH kapena ndodo ya FRP mu GJYXFCH - yomwe imanyamula kulemera kwa chingwecho kudutsa mlengalenga pakati pa malo awiri othandizira., makamaka mizati zothandiza. Izi zimathetsa kufunika kwa waya wopukutira padera, kuphweka kukhazikitsa mlengalenga. Kutalika kwake kwakukulu ndi ~ 80 metres; nthawi yayitali iyenera kugwiritsa ntchito chingwe cha ADSS m'malo mwake.

Kodi kutalika kwa mlengalenga kwa chingwe cha GJYXCH ndi chiyani??

Pafupifupi 80 mamita pakati pa mfundo zothandizira, pamikhalidwe yoyenera. Kupitirira mtunda umenewo, Cable sag imadutsa malire ovomerezeka pansi pa mphepo ndi madzi oundana, ndipo kukangana kwa messenger kumatha kusokoneza ma hardware. Kwa zipata pakati 80 ndi 200+ mita, tumizani chingwe cha ADSS, zomwe zimapangidwira maulendo aatali amlengalenga.

Kodi ndingakwirire chingwe cha GJYXCH mobisa?

Ayi. GJYXCH imakhala ndi jekete kuti iwonetsedwe mumlengalenga ndi UV komanso nyengo, osati kukhudza nthaka, pansi chinyezi kuthamanga, kapena chitetezo cha makoswe. Kuti aikidwe mwachindunji, gwiritsani ntchito chingwe chokhala ndi zida monga GYTA53 chokhala ndi zida zachitsulo-tepi ndi sheathing yoyenera.

Kutalika kwa chingwe chotsitsa cha FTTH pa reel?

Utali wokhazikika wa reel nthawi zambiri 2 ku 3 makilomita kwa GJXFH yamkati / GJXH ndi GJYXCH yakunja. Utali wa reel ndi ng'oma zazikulu zitha kupangidwa poyitanitsa - tsimikizirani zonse zomwe zimaperekedwa komanso zofunikira zilizonse zokhudzana ndi projekiti ndi omwe akukugulirani musanamalize PO.

Ndi mphamvu zotani zomwe chingwe chotsitsa chimafunikira pa projekiti yanga?

Izo zimatengera unsembe zochitika, osati pa dzina la chingwe. Kuyika pakhoma kapena kwakanthawi kochepa m'nyumba nthawi zambiri kumafuna kupanikizika kwanthawi yayitali kwa 40-100 N (GJXFH or GJXH). Conduit pulling, ceiling voids, and short aerial transitions require higher rated cables — even for short outdoor spans, spec GJYXCH at 300 N nthawi yayitali. Under-speccing the tensile rating is the single most common cause of latent micro-fracture failures we see in the field.

How do I verify drop cable quality before accepting delivery?

Request a factory OTDR trace and attenuation report for every reel, keyed to the batch number. Visually inspect the sheath for consistent color, embedded print marking, and no material inconsistency. Random-sample a short section from each shipment, vula m'chimake, and confirm that the strength member material physically matches your PO specification. Any mismatch between the PO and the actual construction should trigger an immediate quality dialogue with the supplier.

Ndi giredi yanji ya fiber yomwe ndiyenera kutchula kuti FTTH itumizidwe mtsogolo?

NenaniG.657.A2 kapena apamwamba. Chingwe chachikale G.657.A1 chikuwonetsa kutayika kwakukulu kopindika pa bend radii pansipa 10 mm, makamaka pa 1625 nm - zenera la kutalika kwa mawonekedwe omwe amagwiritsidwa ntchito pakukulitsa maukonde a XGS-PON 10G FTTH. Kutumiza A1 lero kutha kukakamiza wogwiritsa ntchito kukhala ndi chingwe chokwera mtengo akakonzanso. A2 fiber imagwira ≤ 1.0 dB kutayika kwa a 7.5 mm bend radius pa 1625 nm, kuphimba bwino njira yowonjezeretsa ya wogwiritsa ntchito pamtengo wotsika mtengo.
