Wanpela red-lait pen em i nambawan na isi tul bilong stretim ol hevi bilong 'fiber' - presim baten, putim retpela lait i go insait long 'fiber', na lukim we lait i save lik. Em i kostim planti ten o handet yuan na em i standet ikwipmen bilong olgeta 'fiber engineer'. Tasol ol red-lait pen i gat tripela bikpela hevi.
Wanpela red-lait pen em i nambawan na isi tul bilong stretim ol hevi bilong 'fiber' - presim baten, putim retpela lait i go insait long 'fiber', na lukim we lait i save lik. Em i kostim planti ten o handet yuan na em i standet ikwipmen bilong olgeta 'fiber engineer'. Tasol ol red-lait pen i gat tripela bikpela hevi.
Namba wan: pawa i no inap. Ol nomol red-lait pen i save wok aninit long 1mW, na ol i ken yusim tasol long testim ol 'fiber jumper' insait long haus insait long 500m. Bihain long 1km, retpela lait i save daunim lait na yu no inap lukim. Namba tu: 'wavelength' i no wankain. Ol retpela lait pen i save givim 650nm retpela lait, na ol faiba sistem i save givim 1310nm o 1550nm infraret lait — ol narapela narapela wevlength, olsem na wanpela retpela lait pen i no inap senisim OPM bilong skelim trupela sistem optikal pawa. Namba tri: nogat pawa riding. Wanpela retpela lait pen i save tokim yu tasol olsem 'faiba i konek' o 'faiba i bruk' — em i no inap tokim yu 'signal i strong olsem wanem' o 'link i lus olsem wanem.'
Olsem na, wanpela red-lait pen em i gutpela tasol olsem laspela sekim — bihain long OPM tes, yusim long painimaut hariap sapos wanpela 'jumper' i gat wanpela 'visible break'. Tasol em i no inap long senisim wanpela OPM, na tu em i no inap long pinisim wanpela ful 'fiber link' asesmen.
Red lait sos we i stap insait long olgeta-in-wan divais (olsem PK56B-E series) i gat tripela bikpela samting moa long ol red-lait pen. Namba wan: pawa. PK56B-E retpela lait pawa i save stat long 2mW i go inap 20mW — 2 i go inap 20 taims bilong ol nomol retpela lait pen. Bikpela pawa i min olsem 'detection distance' i longpela na i no inap long kisim lait. Long ol ples we i gat lait ausait long wanpela 'fiber distribution frame', 2mW retpela lait i no inap kamap ples klia, tasol 10mW i stap klia yet.
Namba tu: 'wavelength matching'. Red lait sos na OPM insait long wanpela 'all-in-one' i gat wankain 'fiber interface' na 'calibration system'. Taim yu yusim retpela lait sos long stretim hevi, OPM inap long skelim retpela lait pawa wantaim — em i gutpela tru taim yu stretim ol hevi bilong 'optical amplifier' (EDFA): putim tes lait wantaim retpela lait sos, bihain skelim autput pawa wantaim OPM, na pinisim tupela step insait long wanpela.
Namba tri: wok gut. Sapos yu laik senisim 'red light mode' na 'power test mode' long wanpela 'all-in-one' yu mas presim wanpela baten tasol. Long stretim hevi bilong wanpela 'fiber link', standet 'flow' em: testim pawa (painimaut sapos link i orait) → senisim i go long retpela lait mode (painim bruk) → stretim → testim gen pawa (konfemim ripea). Wantaim ol seperet divais, dispela ron i nidim senis namel long tupela divais, at least taim i go antap tupela taim.
Ol foapela PK56B-E model i gat narapela narapela pawa bilong retpela lait: 10mW, 2mW, 5mW, na 20mW. Dispela i dipen long longpela 'fiber distance' yu mas testim na ples wok bilong yu.
2mW (PK56C): em i gutpela long mekim tes bilong 'indoor fiber jumper' insait long 1km. Liklik pawa konsumsen, longpela laip bilong bateri, liklik prais. Em i gutpela long ol sotpela 'fiber link' insait long ol data senta na ol opis bilding.
5mW (PK56D): em i gutpela samting. Em i gutpela long 2-3km namel-distens faiba link. Yu ken lukim klia insait long haus na ausait long haus. Em i gutpela long planti telekom bes stesin na FTTx fil tes.
10mW (PK56B): i gutpela long 3-5km longpela-distens faiba link. Em i klia yet long ol ples ausait, em i gutpela long mekim wok mentenens na stretim ol hevi bilong 'trunk fiber'.
20mW (PK56E): profesenel gred. Em i gutpela long ol 'fibre link' antap long 5km. Yu ken lukim klia maski san i lait gut, em i gutpela long stretim ol 'trunk cable' na 'long-distance OTDR-assisted positioning'. Toksave: 20mW retpela lait inap long bagarapim ai taim yu stap klostu — noken lukluk stret long 'fiber end-face'.
Red lait tes i luk isi, tasol sampela teknik inap long mekim wok i kamap gutpela moa. Namba wan: 'segmented injection.' Wanpela longpela 'fiber link' i ken gat planti 'splice closures'. Sapos retpela lait i go insait long olgeta link na em i no go insait, noken lukluk long olgeta longpela bilong en — putim retpela lait long wanwan hap: putim long namba wan 'splice closure' na sekim sapos retpela lait i kamap long namba tu. Dispela i save makim hariap wanem hap i gat hevi.
Namba tu: 'bend leakage.' Retpela lait insait long 'fiber' i save lik aut long ol strongpela ben. Taim yu wok long stretim ol hevi bilong 'fiber', muvim retpela lait pen i go long rot bilong 'fiber' - klostu long 'fault point', retpela lait i save lait o lik. Dispela teknik em i gutpela tru long stretim ol hevi we i stap hait olsem 'ol rat i kaikaim ol rop' o 'ol rop we konstraksen i brukim.'
Namba tri: 'filta bilong lait i stap klostu.' Long ol ples we i gat lait ausait o i gat strongpela lait, retpela lait inap long daunim lait bilong en. Yusim 'peak hold' fanksen bilong olgeta-in-wan — retpela lait sos i wok long pulsed mode, na OPM sempel tasol insait long puls windo, na rausim ol lait i stap klostu. PK56B-E series olgeta i sapotim 'pulsed red light mode'.
Namba foa: 'sekim pes pastaim.' Pastaim long putim retpela lait, sekim klinpela bilong 'fiber end-face'. Sapos 'end-face' i gat das, retpela lait i save go nabaut long 'end-face', na i luk olsem wanpela bruk, tasol tru tru em i doti tasol. Sekim wantaim wanpela 'magnifying lens' na klinim sapos i gat nid pastaim long yu mekim tes - dispela i abrusim planti 'misdiagnoses'.
Long ol tim bilong mentenens, putim 'red light testing' insait long wok mentenens bilong 'fiber link'. Long ol nupela 'fiber links', mekim 'red light continuity verification' long taim bilong kisim. Long taim bilong sevis, mekim wok bilong stretim ol hevi long lait long olgeta kwata (long olgeta mun long ol bikpela link). Bihain long wanpela asua, yusim retpela lait sos long painim bruk pastaim, bihain yusim OPM long sekim ripea.
Long ol baia we i stap yet long seleksen hap, putim ol 'all-in-one' divais wantaim ol retpela lait sos i go pas. Taim ol 'all-in-one' yunit i gat bikpela pe moa long ol 'standalone OPM', winmani bilong invesmen i bikpela tru taim yumi skelim wantaim ol 'efficiency gains' na taim bilong stretim ol asua i go daun. Wanpela 'telecom base station fiber break' inap long kamapim planti aua bilong wok bisnis, tasol wanpela 'all-in-one' divais i save painim 'break' insait long 10-pela minit - taim we ol i sevim i winim tru pe bilong divais.
