Wavelength档位 bilong wanpela OPM i makim wanem lait em inap long skelim. Lait long ol narapela narapela wevlength i gat ol narapela narapela transmisen mak insait long faiba, na 'photodetector responsivity' i save senis wantaim 'wavelength' — wankain ditekta inap long kisim tupela taim moa long 850nm olsem long 1550nm. Olsem na, OPM i mas kalibret long stretpela wevlength档位, o ol riding bai i no wok.
Wavelength档位 bilong wanpela OPM i makim wanem lait em inap long skelim. Lait long ol narapela narapela wevlength i gat ol narapela narapela transmisen mak insait long faiba, na 'photodetector responsivity' i save senis wantaim 'wavelength' — wankain ditekta inap long kisim tupela taim moa long 850nm olsem long 1550nm. Olsem na, OPM i mas kalibret long stretpela wevlength档位, o ol riding bai i no wok.
PK56A series i sapotim 7-pela 'wavelength' seting we i karamapim ol bikpela 'fiber communication wavelengths': 850nm (sotpela 'wavelength' bilong 'multimode fiber'), 1310nm (zero-dispersion wavelength bilong 'single-mode fibre'), 1490nm (CATV daunstrim wevlength), 150nm-lowest wavelengths single-mode fiber), 1610nm na 1625nm (out-of-band test wavelengths bilong DWDM sistem). Ol dispela 7-pela wevlengt i karamapim ful spektrum stat long sot-distens multimod i go long long-distens singel-mod, stat long ol ekses netwok i go long ol trunk netwok.
Praktikel veliu bilong seven-wevlengt kavrej em olsem ol fil enjinia i no nidim ol narapela narapela OPM bilong ol narapela narapela sistem. Dispela wankain masin i save testim ol 850nm link insait long ol data senta long makim 850nm档位, i save testim ol 1310nm link long ol telekom bes stesin long makim 1310nm, na i save testim EDFA insait long ol DWDM sistem long makim 1625nm — wanpela baten tasol yu mas presim long senisim.
Ol kain kain 'fiber interface' i gat kain kain — ol i save yusim FC (threaded, ol i save yusim planti taim long CATV na ol tes ikwipmen), SC (push-pull, ol i save yusim planti taim long ol telekom ikwipmen na data senta), ST (push-pull, ol i save yusim planti taim long olpela netwok ikwipmen), na LC (liklik push-pull, ol i save yusim planti taim long ol bikpela data senta). Ol narapela narapela sistem i save yusim ol narapela narapela kain 'interface'. Sapos wanpela OPM i sapotim wanpela 'interface' tasol, ol senis long 'adapter' i save kamap planti taim insait long fil.
PK56A series i kam wantaim FC/UPC na SC/UPP adapta standet, wantaim ST, LC, na ol narapela kain i stap olsem ol opsenel aksesori. Dispela i min olsem ol 'field engineer' i ken senisim hariap ol 'adapter' bihainim 'fiber interface' we ol i yusim - ol i no nidim ol seperet divais long wanwan kain 'interface'.
Narapela veliu bilong ol yunivesel intafes em long testim konsistensi. Ol narapela narapela kain 'interface' i gat ol narapela narapela 'end-face' kwaliti standet - FC 'end-faces' i save stap olsem 'planar', SC 'end-faces' i save stap olsem 'spherical'. Sapos yu yusim stretpela 'adapter' dispela bai mekim gutpela 'physical contact' long taim bilong tes, na bai yu no inap lus moa bikos 'interface' i no wankain.
Multimode fiber (MMF) na single-mode fiber (SMF) em tupela kain fiber. MMF i gat wanpela tikpela 'core' (50 o 62.5μm), i sapotim planti kain 'transmission modes', sotpela mak (planti taim insait long 2km), na i yusim 850nm o 1300nm. SMF i gat wanpela liklik 'core' (9μm), i sapotim wanpela 'transmission mode' tasol, i gat longpela 'reach' (inap long 80km+), na i yusim 1310nm o 1550nm.
PK56A series i sapotim tupela MMF na SMF tes — long 850nm na 1300nm档位 bilong MMF, na long 1310nm, 1490nm, 1550nm, 1610nm, na 1625nm档位 bilong SMF. Dispela i min olsem ol fil enjinia i no nidim ol seperet divais bilong MMF na SMF.
Long praktis, ol wokflo bilong MMF na SMF tes i wankain — makim stretpela wevlength档位, konektim faiba, ritim pawa veliu. Tasol luksave: MMF tes i save yusim 850nm (long wanem ol MM sistem i save yusim 850nm VCSEL sos), na SMF tes i save yusim 1310nm o 1550nm. Sapos yu makim rong wevlength档位 dispela bai kamapim ol riding we i no stret.
Insait long ol PV plent, ol 'fiber communication links' i save salim ol 'inverter operational data' i go long 'central monitoring system'. Sapos wanpela 'fiber link' i bruk, 'monitoring system' i no inap long kisim data bilong 'inverter' - dispela i min olsem PV plent operesen tim i no inap save wanem 'inverter' i gat hevi, wanem pawa autput i stap, o sapos wok bilong en i orait. Long wanpela 100MW PV plent we i gat planti handet inveta, sapos olgeta 'fiber link' i bruk, operesen tim i mas stretim hevi bilong inveta bihain long inveta, na dispela i mas kostim bikpela mani tru.
Ol PV plent faiba link i save bungim ol narakain salens long envairomen. Namba wan: bikpela temperaja bilong ples — ol i save wokim ol PV plent long ol ples we i op, we taim bilong san i hat moa long 60°C, na ol 'fiber' i save mekim ol i go lapun hariap long taim bilong bikpela hat. Namba tu: UV eksposesen — 'polyester buffer layer' bilong 'fiber' i save bagarap aninit long UV rediesen, na dispela i save mekim 'fiber' i bruk bruk. Namba tri: animal i save kaikaim — ol 'cable trenches' na ol 'overhead fiber' insait long ol PV plent em ol gutpela samting bilong ol rat. Namba foa: win na wesan — long ol PV plent bilong ples drai na gobi, win na wesan inap long brukim ausait bilong 'fiber'.
Olsem na, PV plent faiba tes i mas stap insait long plen bilong mentenens oltaim. Long taim bilong kisim nupela plent, testim olgeta 'fiber link' long salim pawa, kisim pawa, na lus bilong link. Long taim bilong sevis, testim pawa na lus bilong ol bikpela link long olgeta kwata. Bihain long wanpela asua, yusim retpela lait sos long painim bruk pastaim, bihain yusim OPM long sekim ripea. PK56A series i gat bikpela tempereja disain (-10°C i go long +50°C) na dispela i mekim em i gutpela long ol PV plent envairomen we i gat bikpela tempereja.
Long ol tim bilong enjiniaring na ol tim bilong mentenens, kamapim ol wokflo bilong testim ol 'fiber'. Wokflo i mas i gat: wok redi pastaim long tes (konfemim wevlengt档位, sekim klinpela bilong end-fes, konfemim kain adapter), tes eksekesen (transmitim pawa → risivim pawa → lus kalkulesen → red lait verifikesen → end-fes poto), post-test rekoding (data arkiv, anomaking ripot, jeneresen).
As bilong standedaisesen em olsem ol tes data bilong 'wankain link, long wankain wevlength, long wankain taim poin' em i wankain. Sapos 'wavelength档位' i senis, 'end-face cleanliness' i senis, na taim bilong tes i senis long olgeta tes, ol i no inap yusim data long skelim 'trend'.
Long ol baia, sapos ol samting bilong yusim divais i karamapim planti kain 'fiber' na planti 'interface', orait putim ol OPM wantaim 'multi-wavelength' na 'multi-interface' sapot. Maski ol dispela kain divais i gat bikpela pe, ol i rausim nid bilong planti divais na daunim hevi bilong makim rong wevlengt o intafeis long taim bilong fil tes.
