Namba wan step long makim wanpela OPM em i no long skelim ol spesifikesen — em long kliagut long wanem wevlength ol 'fiber system' bilong yu i wok long en. Ol narapela narapela sistem i save yusim ol narapela narapela 'wavelength', na ol 'OPM calibration curves' i save senis bihainim dispela. Sapos yu yusim rong wevlength档位 dispela i save kamapim ol riding i go daun long 10% i go inap 20%.
Namba wan step long makim wanpela OPM em i no long skelim ol spesifikesen — em long kliagut long wanem wevlength ol 'fiber system' bilong yu i wok long en. Ol narapela narapela sistem i save yusim ol narapela narapela 'wavelength', na ol 'OPM calibration curves' i save senis bihainim dispela. Sapos yu yusim rong wevlength档位 dispela i save kamapim ol riding i go daun long 10% i go inap 20%.
Ol 'wavelength' we planti manmeri i save yusim long ol 'communications systems' em 1310nm na 1550nm (single-mode fiber low-loss windows) na 850nm (multimode fiber). Ol data senta i save yusim moa yet 850nm VCSEL sos long sotpela-rich transmisen. Ol 'PV plant fiber communication links' i save yusim 1310nm. Sapos ol DWDM (dense wavelength division multiplexing) sistem tu i nidim tes, ol i nidim 1625nm wevlength档位 — 1625nm ol i kolim 'out-of-band wavelength' na ol i yusim long testim EDFA pefomens insait long DWDM sistem na i no stopim sevis.
PK56A series i sapotim 7-pela 'wavelength' seting we i karamapim 850nm, 1310nm, 1490nm, 1550nm, 1610nm, 1625nm, na ol narapela 'mainstream communication wavelength'. Dispela i min olsem maski wanem kain 'wavelength' 'fiber system' bilong yu i yusim, PK56A inap long wankain stret olsem - yu no nidim sampela moa tingting long makim.
OPM reinj i makim hamas strong bilong lait signal em inap long skelim. Sapos em i liklik mak tumas, dispela inap long bagarapim 'detector' wantaim strongpela lait; bikpela mak tumas i no inap long skelim liklik lait. Tasol 'range' i no save 'bikpela moa gutpela' - ol divais we i gat bikpela 'range' i save bikpela moa, i gat bikpela pe, na ating i no gat bikpela 'precision' long 'low-power end' taim yumi skelim wantaim ol masin we i gat wankain 'range'.
Fil tes optikal pawa i save stap namel long -70dBm i go inap long +10dBm. -70dBm em i liklik mak bilong 'sensitivity' bilong planti 'receiver'; +10dBm em i mak bilong planti lait sos. PK56A series ranj i karamapim -70dBm i go long +10dBm, na i wankain stret long dispela ranj.
Sapos ol 'higher-end optical signals' i nidim tes (olsem 'optical amplifier output', we inap long kamap +20dBm), ol i nidim wanpela moa 'optical attenuator' bilong lukautim OPM ditekta. PK56A series i kam wantaim wanpela 'optical attenuator adapta' we yu ken rausim, na i save skruim 'range' i go long +20dBm taim yu nidim.
Bikpela samting i narapela long PK56B na PK56E em pawa bilong retpela lait — 10mW, 2mW, 5mW, na 20mW wanwan. Pawa bilong retpela lait i makim hamas em inap long luksave na hamas em i wok gut aninit long lait bilong ples.
Wok bilong retpela lait em long putim retpela lait (650nm) i go insait long 'fiber' na lukluk long wanem hap lait i save lik long en bilong luksave long ol hap we i bruk. Bikpela pawa i min olsem longpela taim bilong painim samting na gutpela lukluk aninit long strongpela lait. 2mW (PK56C) em i gutpela long sotpela-distens (1-2km) 'indoor fiber jumper' tes, wantaim liklik pawa konsumsen, longpela laip bilong bateri, na liklik prais. 5mW (PK56D) em i gutpela samting, na i gutpela long planti 'medium-distance' fil tes. 10mW (PK56B) em bilong stretim hevi bilong ol 'fiber link' we i stap longwe (3-5km). 20mW (PK56E) em i profesenel gred, em i gutpela long longwe (5km+) 'trunk fiber' tes, na i stap klia yet maski i gat lait ausait.
Noken painim bikpela pawa taim yu makim. 20mW retpela lait i ken lait tumas long yusim insait long haus, na yu mas gat samting bilong lukautim ai. Na ol retpela lait we i gat bikpela pawa i save kisim moa pawa, na dispela i save mekim laip bilong bateri i sotpela taim. Yu mas makim pawa bilong retpela lait bihainim longpela 'fiber distance' yu mas traim.
OPM na retpela lait sos i ken stap wantaim (olgeta insait long wanpela) o seperet — wanpela standalone OPM na wanpela seperet retpela lait pen. Olgeta wan wan rot i gat gutpela na nogut sait, tasol long ol 'field testing' senario, olgeta samting insait long wanpela i gat klia gutpela samting.
Namba wan: inap long karim. Wanpela 'all-in-one' em i wanpela masin tasol; seperet i min olsem tupela. Ol fil enjinia i save muv namel long ol tes poin — stat long ol ples hait bilong ol 'base station' i go long ol 'fiber distribution frame', stat long ol data senta Zon A i go long Zon B — na sapos ol i karim wanpela liklik masin, dispela i min olsem ol i no gat planti hevi.
Namba tu: wok gut. Olgeta-in-wan i no nidim senis namel long OPM na retpela lait pen mod — wanpela baten tasol i save senisim namel long pawa tes na retpela lait mod. Long stretim hevi bilong wanpela 'fiber link', standet 'flow' em: traim pawa (painimaut sapos link i orait) → senisim i go long retpela lait mod (painim bruk) → stretim bruk → traim gen pawa (konfemim ripea). Wantaim ol seperet divais, dispela ron i nidim senis i go i kam namel long tupela divais, na dispela i daunim wok bilong en long hap.
Namba tri: kos. Maski wanpela 'all-in-one' yunit i gat bikpela pe moa long wanpela 'standalone OPM', sapos yu putim prais bilong wanpela 'red light pen', 'all-in-one' i save liklik pe. Na wantaim wanpela bateri tasol long menesim, i gat wanpela liklik saja long karim.
Namba foa: data korelesen. Ol data we ol i rekodim long taim bilong pawa tes long wanpela 'all-in-one' i ken i go wantaim ol 'red light test' risal insait long wankain tes rekot. Ol i brukim ol seperet data bilong divais, na i nidim manuel matching long taim bilong bihain analisis — em i as bilong asua.
Bihain long seleksen, ol hap bilong kisim na salim ol samting i gat ol hevi bilong ol yet. Taim yu baim, noken skelim prais tasol — askim long wanpela 'demo unit' bilong 'on-site validation'. Ol samting we i soim olsem ol kampani i wokim ol samting i no wankain long 'spec sheet': 'interface friendliness', 'fiber adapter compatibility', 'red light source braitness' - nogat wanpela bilong ol dispela samting i kamap long ol 'spec sheet' tasol olgeta i save mekim wok bilong en i kamap stret.
Taim ol ikwipmen i kamap, noken tilim stret long ol wokmanmeri bilong fil. Mekim supavaisa bilong enjiniaring i traim dispela samting inap wanpela wik, na painimaut olsem em i wok gut wantaim ol kain 'fiber' na ol samting i stap long envairomen, na bihain stretim trening bilong ol wokmanmeri. Trening i mas karamapim: stretpela tes prosedur (wevlengt seleksen → end-fes inspeksen → pawa tes → lus kalkulesen → red lait verifikasen), ol data rekoding praktis, risal intapretesen kraeteria (wanem samting i makim PASS, WARNING, na FAIL), na besik ikwipmen mentenens.
Kamapim wanpela data menesmen rejim em i bikpela samting tu. Bihain long olgeta tes, ol data i mas go insait long enjiniaring menesmen sistem, na ol i mas putim long link namba na taim sekwens. Wokim wanpela kwata fiber link helt ripot we i listim olgeta link we i gat 'abnormal loss', na putim long 'urgency' bilong mekim wok mentenens. Dispela i senisim wok bilong lukautim ol 'fiber' long 'reactive repair' i go long 'proactive early warning' - em wanpela rot tasol we ol tes data i save givim gutpela samting tru.
