Rɛd-layt pen na di tin we smɔl ɛn simpul fɔ sɔlv di prɔblɛm wit di fayv — prɛs di bɔtin, injɛkt rɛd layt insay di fayv, ɛn si usay layt de lik. I de kɔst tɛn to ɔndrɛd yuan ɛn na standad ikwipmɛnt fɔ ɛvri fayv injinia. Bɔt pen dɛn we gɛt rɛd layt gɛt tri men tin dɛn we dɛn nɔ ebul fɔ du.
Rɛd-layt pen na di tin we smɔl ɛn simpul fɔ sɔlv di prɔblɛm wit di fayv — prɛs di bɔtin, injɛkt rɛd layt insay di fayv, ɛn si usay layt de lik. I de kɔst tɛn to ɔndrɛd yuan ɛn na standad ikwipmɛnt fɔ ɛvri fayv injinia. Bɔt pen dɛn we gɛt rɛd layt gɛt tri men tin dɛn we dɛn nɔ ebul fɔ du.
Fɔs: nɔ gɛt bɛtɛ pawa. Ɔdinari rɛd-layt pen dɛn kin wok ɔnda 1mW, we dɛn kin yuz nɔmɔ fɔ indo fayba jɔmpa tɛst insay 500m. Bifo 1km, di red layt de attenuate to invisibility. Sɛkɔn: di wevlɛnj mismatch. Rɛd-layt pen dɛn de gi 650nm rɛd layt we pɔsin kin si, we fayv sistɛm dɛn kin transmit 1310nm ɔ 1550nm infrarɛd layt — difrɛn wevlɛnj dɛn, so rɛd-layt pen nɔ kin ebul fɔ tek ples fɔ OPM fɔ mɛzhɔ di aktual sistɛm ɔptik pawa. Tɔd: nɔ gɛt pawa ridin. Rɛd layt pen de jɔs tɛl yu se ‘di fayv dɔn kɔnɛkt’ ɔ ‘di fayv dɔn brok’ — i nɔ go ebul fɔ tɛl yu ‘aw di signal strɔng’ ɔ ‘wetin di link lɔs.’
So, wan rɛd-layt pen fit ɔl as fayn chɛk — afta OPM tɛst, yuz am fɔ kɔnfɔm kwik kwik wan if pɔsin we de jomp gɛt brek we pɔsin kin si. Bɔt i nɔ kin ebul fɔ tek ples fɔ wan OPM, ɛn i nɔ kin ebul fɔ kɔmplit wan ful fayba link asɛsmɛnt fɔ insɛf.
Di intagreted red layt sɔs in ɔl-in-wan divays (lɛk di PK56B–E siriɔs) de gi tri impɔtant ɔpgrɛd oba rɛd-layt pen. Fɔs: pawa. PK56B–E rɛd layt pawa de frɔm 2mW to 20mW — 2 to 20 tɛm di wan we ɔdinari rɛd-layt pen dɛn gɛt. Ay pawa min se di distans fɔ ditekshɔn lɔng ɛn bɛtɛ rɛsistɛns to layt we de rawnd. Insay brayt ɔda kɔndishɔn na fayv distribyushɔn freym, 2mW rɛd layt kin nɔ de si am ɔl, we 10mW kin stil de klia wan.
Sɛkɔn: wevlɛnj maching. Di rɛd layt sɔs ɛn OPM insay wan ɔl-in-wan de sheb di sem fayba intafɛs ɛn kalibreshɔn sistɛm. We yu de yuz di rɛd layt sɔs fɔ sɔlv prɔblɛm, di OPM kin mɛzhɔ rɛd layt pawa wan tɛm — i kin yus mɔ we yu de sɔlv di optik amplifaya (EDFA) fɔlt: injɛkt tɛst layt wit di rɛd layt sɔs, dɔn mɛzhɔ di ɔtput pawa wit di OPM, ɛn kɔmplit tu stɛp dɛn insay wan.
Tɔd: ɔpreshɔnal efyushɔn. Fɔ chenj bitwin rɛd layt mɔd ɛn pawa tɛst mɔd pan ɔl-in-wan, yu nid fɔ prɛs wan bɔtin. We yu de sɔlv prɔblɛm wit fayv link, di standad flɔ na: tɛst pawa (ditarmin if di link nɔmal) → swich to rɛd layt mɔd (luk di brek) → fiks → ritest pawa (kɔnfɛm ripa). Wit difrɛn divays dɛn, dis flɔ nid fɔ chenj bitwin tu divays dɛn, at ɔl fɔ dubl di tɛm.
Di 4 PK56B–E mɔdel dɛn difrɛn pan rɛd layt pawa: 10mW, 2mW, 5mW, ɛn 20mW. Di choice dipen pan di longest fiber distance we yu nid fɔ test ɛn di say we yu de wok.
2mW (PK56C): fayn fɔ indo fayba jɔmpa tɛst insay 1km. Di pawa we smɔl pas ɔl, di bateri layf we lɔng pas ɔl, di prayz we smɔl pas ɔl. I fayn fɔ shɔt-distans fayba link dɛn insay data sɛnta ɛn ɔfis bildin dɛn.
5mW (PK56D): di balans choice. I fayn fɔ 2-3km midul-distans fayba link dɛn. Yu kin si am klia wan na ɔl tu di say dɛn we de insay ɛn we nɔ de na do. I fayn fɔ mɔs tɛlikɔm bays steshɔn ɛn FTTx fil tɛst dɛn.
10mW (PK56B): fayn fɔ 3-5km lɔng-distans fayv link dɛn. I stil klia na do ɛnvayrɔmɛnt, fayn fɔ rutin mentenɛns ɛn trɔbul fɔ sɔlv di trɔnk fayba.
20mW (PK56E): profeshɔnal gred. I fayn fɔ fayv link dɛn we pas 5km. Yu kin si am klia wan ivin we yu de shayn brayt de, i fayn fɔ mek yu ripɛnt di trɔnk kebul ɛn fɔ mek yu ebul fɔ put am we OTDR de ɛp fɔ lɔng distans. Notis: 20mW rεd layt kin bi denja to di yay dεm we yu de klos — avכyd fכ luk dairekt pan di fayv εnd-fes.
I tan lɛk se fɔ tɛst rɛd layt simpul, bɔt sɔm we dɛn kin mek di wok fayn fayn wan. Fɔs: ‘segmɛnt injɛkshɔn.’ Wan lכng fayv link kin gεt mכltipכl splais kloz dεm. If dɛn injɛkt rɛd layt insay di ɔl link ɛn i nɔ pas, nɔ skan di wan ol lɔng wit yu yay — injɛkt rɛd layt sɛgmɛnt bay sɛgmɛnt: injɛkt na di fɔs splais klos ɛn chɛk if rɛd layt rich di sɛkɔn wan. Dis kin ayd kwik kwik wan us sɛgmɛnt gɛt di prɔblɛm.
Sɛkɔn: ‘bɛnd lik.’ Rɛd layt we de insay fayv kin lik kɔmɔt na say dɛn we strɔng. We yu de sɔlv prɔblɛm wit di fayv fɔlt, muv di rɛd layt pen along di fayv pat — nia di say we di fɔlt de, rɛd layt kin brayt ɔ lik wantɛm wantɛm. Dis teknik kin yus mɔ fɔ sɔlv prɔblɛm dɛn we ayd lɛk ‘fayba we rat dɔn chew’ ɔ ‘fayba we dɛn dɔn krɔs bay we dɛn de bil.’
Tɔd: ‘ambient layt filta.’ Insay say dɛn we brayt na do ɔ we gɛt strɔng layt, layt we de arawnd kin ful-ɔp wit rɛd layt. Yuz di ɔl-in-wan in ‘pik hold’ fɛnshɔn — di rɛd layt sɔs de wok insay puls mɔd, ɛn di OPM sɛmpul dɛn nɔmɔ insay di puls winda, we de filta aut ambiɛnt layt intafɛreshɔn. PK56B–E siriɔs ɔl sɔpɔt pulsed rɛd layt mɔd.
Fɔs: ‘ɛnd-fes inspekshɔn fɔs.’ Bifo yu injekt rɛd layt, inspɛkt di fayv ɛnd-fes klin. If di ɛnd-fes gɛt dɔti, rɛd layt kin skata na di ɛnd-fes, i kin tan lɛk brek, we i rili jɔs dɔti. Inspek wit magnifying lens ɛn klin if nid de bifo yu tɛst — dis de avɔyd bɔku bɔku misdiagnosis.
Fɔ mentenɛns tim dɛn, intagret rɛd layt tɛst insay rutin fayba link mentenɛns. Fɔ nyu fayba link, du rɛd layt kɔntinyuiti verifyeshɔn we yu de aksept. We yu de du savis, du rɛd layt trɔbulshut ɛvri kwata (ɛvri mɔnt fɔ impɔtant link dɛn). Afta fɔlt, yuz di rɛd layt sɔs fɔ fɛn di brek fɔs, dɔn yuz di OPM fɔ chɛk fɔ si if dɛn dɔn ripɛnt am.
Fɔ di wan dɛn we de bay we stil de na di say we dɛn de pik, put ɔl-in-wan divays dɛn we gɛt rɛd layt sɔs fɔs. Wail ɔl-in-wan yunit dɛn de kɔst mɔ pas standalɔn OPM dɛn, di ritɔn ɔn invɛstmɛnt na bɔku we dɛn mɛzhɔ am agens di efyushɔn gens ɛn ridyus fɔlt ripa tɛm. Wan singl tɛlikɔm bays steshɔn fayba brek kin mek bɔku awa biznɛs intarapshɔn, we ɔl-in-wan divays kin fɛn di brek insay 10 minit — di tɛm we dɛn sev pas di divays kɔst fa fawe.
