1. Isifinyezo Somkhiqizo

Isamukeli se-ZBR1001JL yi-1GHz FTTB eyamukelayo ebonakalayo yakamuva. Ngobubanzi obubanzi bokuthola amandla we-optical, izinga lokukhipha okuphezulu nokusetshenziswa kwamandla okuphansi. Kuyimishini ekahle yokwakha inethiwekhi yokusebenza ye-NGB ephezulu.

2. Izici Zokusebenza

■ Inqubo yokulawula i-Optical Optical ye-Optical, lapho uhla lwamandla wokufaka lunjalo -9~ +2dBm, izinga lokukhiphayo, i-CTB ne-CSO empeleni alishintshiwe;

■ Imvamisa yokusebenza kwe-Downlink enwetshelwe ku-1GHz, ingxenye ye-RF amplifier isebenzisa ukusebenza okuphezulu kwamandla we-GaAs chip, izinga eliphakeme kakhulu lokukhipha elifinyelela ku-112dBuv;

■ I-EQ ne-ATT zombili zisebenzisa isekethe lokulawula ugesi elisebenza ngogesi, lenza isilawuli sibe ngokunembe kakhudlwana, ukusebenza kube lula kakhulu;

■ Isiphenduli sokuphathwa kwenethiwekhi sikazwelonke esijwayelekile II sesigaba sesibili, sisekela ukuphathwa kwenethiwekhi okukude (uma uthanda);

■ Isakhiwo esihlanganisiwe, ukufakwa okulula, imishini yokuqala yokukhetha yenethiwekhi ye-FTTB CATV;

■ Ukunikezwa kwamandla kagesi okuthembeke okuphezulu okwakhelwe ngaphakathi, namandla kagesi angaphandle akhethiwe;

6. Indlela ehlanzekile neyokulondoloza yesixhumi esisebenzayo se-fiber fiber

Ezikhathini eziningi, sikubheka kabi ukwehla kwamandla kagesi noma ukunciphisa izinga lokukhipha isamukeli njengamaphutha emishini, kepha empeleni kungabangelwa ukuxhumana okungelona kwesixhumi se-fiber noma isixhumi se-fiber kungcoliswe uthuli noma ukungcola.

Manje wethula izindlela ezivamile ezihlanzekile nezokulondoloza zesixhumi esisebenzayo se-fiber.

1.Qaphela ngokucophelela isixhumi esisebenzayo se-fiber kusuka ku-adaptha. Isixhumi esisebenza nge-fiber esebenzayo akufanele sikhombe emzimbeni womuntu noma ngamehlo anqunu ukugwema ukulimala ngengozi.

2.Wash ngokucophelela ngekhwalithi enhle yokusula iphepha noma ukotini wokwehlisa utshwala. Uma usebenzisa ukotini we-degrease wotshwala wezokwelapha, kusadingeka ulinde imizuzu eyi-1 ~ 2 ngemuva kokuwashwa, vumela indawo yokuxhuma yomile emoyeni.

Isixhumi esisebenzayo esihlanjiwe se-fiber kufanele sixhunywe kwimitha yamandla wokulinganisa ukukala amandla wokukhipha okuqinisekisayo ukuthi kuhlanzwe yini.

4.When isikulufu sihlanze fiber optical isixhumi esisebenza emuva ku-adaptha, kufanele uqaphele ukwenza amandla afanele ukugwema ithubhu le-ceramic ku-adaptha ufa.

5.Uma amandla wokukhipha we-optical engejwayelekile ngemuva kokuhlanzwa, kufanele aqothule i-adaptha bese uhlanza esinye isixhumi. Uma amandla we-optical esephansi ngemuva kokuhlanzwa, i-adaptha ingahle ingcoliswe, uyihlanze. (Qaphela: Qaphela lapho uqothula i-adaptha ukugwema ukulimaza ngaphakathi kwefayibha.

6.Sebenzisa umoya ozinikele onomfutho noma we-degrease alcohol bar bar ukuhlanza i-adaptha. Lapho usebenzisa umoya ocindezelweyo, isifonyo sethangi lomoya elicindezelwe kufanele ligxile kuthubhu ye-ceramic ye-adaptha, ihlanze ithubhu le-ceramic ngomoya ocindezelweyo. Lapho usebenzisa i-degrease alcohol bar bar ukotini, faka ngokucophelela ibha yotshwala yotshwala kuthubhu ye-ceramic ukuze uyihlanze. Inkomba yokufaka kufanele ihambisane, ngaphandle kwalokho ayikwazi ukufinyelela umphumela omuhle wokuhlanza.

7. Incazelo yenkonzo yokuthengisa ngemuva

1.Siyathembisa: Iwaranti yamahhala izinyanga eziyishumi nantathu (Shiya isikhathi sefektri kusitifiketi semfanelo yomkhiqizo njengosuku lokuqala). Isikhathi sewaranti eseluliwe sisuselwa kusivumelwano sokunikezela. Sinesibopho sokunakekelwa kwempilo yonke. Uma iphutha lesisetshenziswa libangelwa ukusebenza ngokungafanele kwabasebenzisi noma izizathu ezingenakugwenywa zemvelo, sizoba nesibopho sokulungisa kodwa sicele izindleko zezinto ezifanelekile.

2. Lapho imishini iphuka, ngokushesha shayela ucingo lwethu losizo lobuchwepheshe i-hotline 8613675891280

3.Ukulondolozwa kwesiza semishini enamaphutha kufanele kusetshenziswe ngochwepheshe abangochwepheshe ukugwema ukulimala okubi kakhulu.

Isaziso esikhethekile: Uma okokusebenza kugcinwe ngabasebenzisi, ngeke sibhekane nesondlo samahhala. Sizocela izindleko ezifanele zokugcinwa kanye nezindleko zempahla.
