Izimbobo zokuphuma kwe-Com: 4-32 ozikhethela;
Amandla okukhiphayo okubonakalayo: okukhiphayo okuphelele kufika ku-15W (41dBm);
Isibalo somsindo ophansi: <6dB uma okokufaka kungu-0dBm;
I-interface yokuphatha inethiwekhi ephelele, ngokuhambisana nokuphathwa kwenethiwekhi okujwayelekile kwe-SNMP;
Isistimu yokulawula izinga lokushisa ehlakaniphile yenza ukusetshenziswa kwamandla kube phansi;
Into Iyunithi Amapharamitha wobuchwepheshe Phawula Umkhawulokudonsa osebenzayo nm 1545 - 1565 Ibanga lamandla okufakwayo okubonakalayo dBm -3 - +10 Ubukhulu:-10-+10 Isikhathi sokushintsha i-Optical ms ≤ 5 Amandla aphezulu okukhiphayo dBm 41 Ukuqina kwamandla okukhiphayo dBm ±0.5 Isibalo somsindo dB ≤ 6.0 Amandla okufaka abonakalayo 0dBm, λ=1550nm Buyisela ukulahlekelwa Okokufaka dB ≥ 45 Okukhiphayo dB ≥ 45 Uhlobo Lwesixhumi esibonakalayo I-CATV IN:SC/APC, I-PON: SC/PC NOMA LC/PC COM:SC/APC NOMA LC/APC Ukulahleka kokufakwa kwembobo ye-PON kuya ku-COM ≤ 1.0 dBm C/N dB ≥ 50 Isimo sokuhlola ngokusho I-GT/T 184-2002. C/CTB dB ≥ 63 C/CSO dB ≥ 63 I-voltage yokuphakelwa kwamandla V A: AC100V – 260V (50 Hz~60Hz) B: DC48V(50 Hz~60Hz) C:DC12V(50 Hz~60Hz) Ibanga lokushisa elisebenzayo °C -10 - +42 Ubuningi bomswakama ohlobene osebenzayo % Ubukhulu obungu-95% akukho ukufingqa Isitoreji esiphezulu somswakama ohlobene % Ubukhulu obungu-95% akukho ukufingqa Ubukhulu mm 483(L)×440(W)×88(H)
Izinyathelo zokufaka
1. Ngaphambi kokufaka okokusebenza, sicela ufunde ngokucophelela bese ufaka okokusebenza ngokuya nge-.Qaphela: Ngomonakalo owenziwe umuntu kanye neminye yonke imiphumela edalwe ukufakwa kwephutha okungahambisani ne-, ngeke sibe nesibopho futhi ngeke sinikeze iwaranti yamahhala.
2. Khipha idivayisi ebhokisini;lungisa ku-rack futhi ubeke phansi ngokuthembekile.(Ukumelana okuphansi kufanele kube <4Ω).
3. Sebenzisa i-multimeter yedijithali ukuze uhlole i-voltage yokunikezela, qiniseka ukuthi i-voltage yokuhlinzeka ihambisana nezidingo kanye nokhiye wokushintsha usendaweni ethi "VALIWE".Bese uxhuma ukunikezwa kwamandla.
4. Faka isignali yokubona ngokomlayezo wesibonisi.Vula inkinobho yokushintsha uye endaweni ethi "VULIWE" bese ubheka isimo se-LED yephaneli yangaphambili.Ngemuva kokuthi inkomba yesimo sokusebenza sephampu iphenduke ibe luhlaza, idivayisi isebenza ngokujwayelekile.Bese ucindezela inkinobho yemenyu kuphaneli yangaphambili ukuze uhlole imingcele yokusebenza.
5. Xhuma imitha yamandla okubona ekugcineni kokuphumayo kwesignali nge-jumper evamile yokuhlola i-fiber optical, bese ukala amandla okukhiphayo okubonayo.Qinisekisa amandla okukhiphayo alinganisiwe kanye namandla abonisiwe ayafana futhi afinyelele inani elincane.(Qinisekisa ukuthi imitha yamandla okukhanya isendaweni yokuhlola i-wavelength engu-1550nm; i-optical fibre test jumper iyona efanisiwe futhi endaweni yesixhumi ayinakho ukungcola.) Susa i-jumper yokuhlola i-fiber optical ejwayelekile kanye imitha yamandla optical;xhuma idivayisi kunethiwekhi.Kuze kube manje, idivayisi isifakwe ngokuphelele futhi yalungiswa.
