Amandla okukhipha okubonakalayo: inani lokukhipha elifinyelela ku-15W（41dBm）;
Isibalo somsindo ophansi: <6dB uma okokufaka kungu-0dBm;
Isixhumi esibonakalayo sokuphathwa kwenethiwekhi esiphelele, esihambisana nokuphathwa kwenethiwekhi okujwayelekile kwe-SNMP;
Uhlelo lokulawula izinga lokushisa oluhlakaniphile lwenza ukusetshenziswa kwamandla kube phansi;
Into Iyunithi Amapharamitha ezobuchwepheshe Isaziso Umkhawulokudonsa wokusebenza nm 1545 - 1565 Ububanzi bamandla okufaka okubonakalayo i-dBm -3 - +10 Ucingo oluphezulu: -10- +10 Isikhathi sokushintsha kwe-Optical ms ≤ 5 Amandla aphezulu okukhipha optical i-dBm 41 Ukuqina kwamandla okukhipha i-dBm ±0.5 Isibalo somsindo dB ≤ 6.0 Amandla okufaka okubonakalayo 0dBm, λ=1550nm Ukulahlekelwa yimbuyiselo Okokufaka dB ≥ 45 Umphumela dB ≥ 45 Uhlobo Lwesixhumi Esibonakalayo I-CATV IN:SC/APC, I-PON: SC/PC NOMA LC/PC I-COM:SC/APC noma i-LC/APC Ukulahlekelwa kokufakwa kwembobo ye-PON kuya ku-COM ≤ 1.0 i-dBm C/N dB ≥ 50 Isimo sokuhlola ngokusho I-GT/T 184-2002. I-C/CTB dB ≥ 63 I-C/CSO dB ≥ 63 I-voltage yokunikezwa kwamandla V A: AC100V – 260V (50 Hz~60Hz) B: DC48V(50 Hz~60Hz) C:DC12V(50 Hz~60Hz) Ibanga lokushisa lokusebenza °C -10 – +42 Umswakama osebenzayo ophezulu % Ubuningi obungu-95% akukho ukujiya Umswakama olinganiselwe wokugcina % Ubuningi obungu-95% akukho ukujiya Ubukhulu mm 483(L)×440(W)×88(H)
Izinyathelo zokufaka
1. Ngaphambi kokufaka imishini, sicela ufunde ngokucophelela bese ufaka imishini ngokuya nge-. Qaphela: Ngomonakalo owenziwe ngumuntu kanye neminye imiphumela ebangelwa ukufakwa kwephutha okungeyona ngokwe-, ngeke sibe nesibopho futhi ngeke sinikeze iwaranti yamahhala.
2. Khipha idivayisi ebhokisini; yilungise erekhini bese uyibeka phansi ngendlela ethembekile. (Ukumelana nokumisa phansi kumele kube <4Ω).
3. Sebenzisa i-multimeter yedijithali ukuhlola i-voltage yokunikezela, qiniseka ukuthi i-voltage yokunikezela iyahambisana nezidingo futhi inkinobho yokushintsha isendaweni ethi “VALIWE”. Bese uxhuma i-power supply.
4. Faka isignali yokukhanya ngokuya ngomyalezo wokubonisa. Jika inkinobho yokushintsha uye endaweni ethi “VULIWE” bese ubheka isimo se-LED sephaneli engaphambili. Ngemva kokuba isibonakaliso sesimo sokusebenza kwephampu siphenduke sibe luhlaza, idivayisi isebenza ngendlela evamile. Bese ucindezela inkinobho yemenyu kuphaneli engaphambili ukuze uhlole amapharamitha okusebenza.
5. Xhuma imitha yamandla okukhanya ekugcineni kokukhipha isignali yokukhanya nge-jumper yokuhlola i-fiber yokukhanya ejwayelekile, bese ulinganisa amandla okukhipha okukhanya. Qinisekisa ukuthi amandla okukhipha okukhanya alinganisiwe kanye namandla abonisiwe ayafana futhi afinyelele inani elilinganiselwe. (Qinisekisa ukuthi imitha yamandla okukhanya isendaweni yokuhlola ubude be-wavelength obungu-1550nm; i-jumper yokuhlola i-fiber yokukhanya yiyona efanisiwe futhi ebusweni besixhumi ayinakho ukungcola.) Susa i-jumper yokuhlola i-fiber yokukhanya ejwayelekile kanye nemitha yamandla okukhanya; xhuma idivayisi kunethiwekhi. Kuze kube manje, idivayisi isifakiwe ngokuphelele futhi ilungisiwe.
