1. Ukuthelekisa iindleko
(1) Iindleko zemodyuli yePON:
Ngenxa yobunzima bobugcisa kunye nokudibanisa okuphezulu, iindleko zeemodyuli ze-PON ziphezulu. Oku ikakhulu ngenxa yeendleko eziphezulu zeetshiphusi ezisebenzayo (ezifana ne-DFB kunye ne-APD chips), ezithatha umlinganiselo omkhulu weemodyuli. Ukongeza, iimodyuli ze-PON zibandakanya ezinye ii-ICs zesekethe, iinxalenye zesakhiwo, kunye nezinto ezivelisayo, eziya kwandisa iindleko zayo.
(2) Iindleko zemodyuli ye-SFP:
Xa kuthelekiswa, iindleko zeemodyuli ze-SFP zincinci. Nangona ifuna ukuthumela kunye nokufumana iitshiphusi (ezifana ne-FP kunye ne-PIN chips), iindleko zezi chips ziphantsi kunezo zeechips kwiimodyuli zePON. Ukongeza, umgangatho ophezulu wokulinganisa iimodyuli ze-SFP nazo zinceda ukunciphisa iindleko zayo.
2. Ukuthelekisa ukugcinwa
(1) Ugcino lwemodyuli yePON:
Ukugcinwa kweemodyuli zePON kunzima. Ekubeni amanethiwekhi e-PON abandakanya ii-nodes ezininzi kunye nokuhanjiswa kwexesha elide, kuyimfuneko ukujonga rhoqo umgangatho wokuhanjiswa, amandla, kunye nesimo se-fiber optical connectors of optical signals. Ukongeza, iimodyuli ze-PON nazo kufuneka zithathele ingqalelo imeko yokusebenza ngokubanzi kwenethiwekhi ukufumanisa ngokukhawuleza kunye nokusombulula iingxaki ezinokubakho.
(2) Ukugcinwa kwemodyuli ye-SFP:
Ukugcinwa kweemodyuli ze-SFP kulula. Ngenxa yoyilo lwemodyuli kunye nomsebenzi otshisayo, ukutshintshwa kunye nokulungiswa kweemodyuli ze-SFP zilula. Ngexesha elifanayo, i-interface esemgangathweni yeemodyuli ze-SFP nazo zinciphisa ubunzima bokugcinwa. Nangona kunjalo, kusekho ukucoca rhoqo i-interface yemodyuli ye-optical kunye ne-fiber connector ukuqinisekisa ukuba iindawo zabo azikho uthuli kunye nokungcola ukuze kugcinwe umgangatho kunye nokuzinza kwesignali ye-optical.
Isishwankathelo, iindleko zeemodyuli ze-PON ziphezulu kwaye ukugcinwa kunzima; ngelixa iindleko zeemodyuli ze-SFP zincinci kwaye ukugcinwa kulula. Kwimimandla yenethiwekhi enkulu kunye neyinkimbinkimbi, iimodyuli zePON zinokufaneleka ngakumbi; ngelixa ngezihlandlo ezifuna ukufakela ngokukhawuleza kunye nokutshintshwa, iimodyuli ze-SFP zinokufaneleka ngakumbi. Ngexesha elifanayo, kungakhathaliseki ukuba yiyiphi imodyuli ye-optical esetyenzisiweyo, ukugcinwa rhoqo kunye nomsebenzi wokunyamekela kufuneka kwenziwe ukuze kuqinisekiswe ukusebenza okuzinzile kwenethiwekhi.
