Sɛvin-Wevlɛnj Kɔvarej: Wetin Mek Wevlɛnj Sɛlɛkshɔn Na Kɔr to di OPM

Di wevlɛnj档位 fɔ wan OPM de sho us layt i kin mɛzhɔ. Layt na difrεn wevlεngth gεt difrεn transmishכn kכntribyushכn dεm na fayv, εn fכtoditekta rεspכnsiviti de vεryus wit wevlεngth — di sem dεtekta kin bi tu tεm sεnsitiv na 850nm lεk na 1550nm. So, di OPM fɔ kalibrayt na di kɔrɛkt wevlɛnj档位, ɔ di ridin dɛn go ɔf.

Di PK56A siriɔs sɔpɔt sɛvin wɛvlɛnj sɛtin dɛn we de kɔba di men fayba kɔmyunikeshɔn wɛvlɛnj dɛn: 850nm (shɔt wɛvlɛnj fɔ maltimod fayba), 1310nm (ziro-dispershɔn wɛvlɛnj fɔ singl-mɔd fayba), 1490nm (CATV daunstrim wɛvlɛnj), 1550nm (lɔs-lɔs wɛvlɛnj fɔ singl-mod fayba), 1610nm ɛn 1625nm (ɔt-ɔf-band tɛst wɛvlɛnj fɔ DWDM sistɛm dɛn). Dɛn sɛvin wevlɛnj ya de kɔba di ful spɛktrum frɔm shɔt-distans maltimɔd to lɔng-distans singl-mɔd, frɔm akses nɛtwɔk to trɔnk nɛtwɔk.

Di prɛktikal valyu fɔ sɛvin-wevlɛnj kɔvarej na dat fil injinia dɛn nɔ nid difrɛn OPM fɔ difrɛn sistɛm dɛn. Di sem divays de tɛst 850nm link dɛn na data sɛnta bay we i pik di 850nm档位, i de tɛst 1310nm link dɛn na tɛlikɔm bays steshɔn dɛn bay we i pik 1310nm, ɛn i de tɛst EDFA na DWDM sistem bay we i pik 1625nm — wan bɔtin we yu prɛs fɔ swich.

Yunivasal Intafeys: FC / SC / ST / LC Ɔl dɛn kɔba

Fayba intafeys tayp dɛn difrɛn — kɔmɔn kayn dɛn inklud FC (threaded, we dɛn kin yuz fɔ CATV ɛn tɛst ikwipmɛnt), SC (push-pul, we dɛn kin yuz na tɛlikɔm ikwipmɛnt ɛn data sɛnta), ST (push-pul, we dɛn kin yuz na ol nɛtwɔk ikwipmɛnt), ɛn LC (smɔl push-pul, we dɛn kin yuz na ay-dɛnsity data sɛnta). Difrɛn sistɛm dɛn de yuz difrɛn kayn intafɛs. If wan OPM sɔpɔt wan intafɛs nɔmɔ, chenj dɛn na di adapt kin apin bɔku tɛm na di fil.

Di PK56A siriɔs ship wit FC/UPC ɛn SC/UPP adapt dɛn standad, wit ST, LC, ɛn ɔda kayn dɛn we de as opshɔnal aksesɔri. Dis min se fil injinia dɛn kin chenj adapt dɛn kwik kwik wan bay di aktual fayba intafɛs we dɛn yuz — nɔ nid fɔ gɛt sɛpret divays dɛn fɔ ɛni intafɛs tayp.

Wan ɔda valyu fɔ yunivasal intafɛs na fɔ tɛst kɔnsistɛns. Difrɛn intafɛs tayp dɛn gɛt difrɛn ɛnd-fes kwaliti standad — FC ɛnd-fes dɛn tipikli planar, SC ɛnd-fes dɛn tipikli sfɛrikal. Yuz di kɔrɛkt adapt de mek shɔ se yu gɛt di rayt fizik kɔntakt we yu de tɛst, ɛn dis de mek yu nɔ gɛt ɛkstra lɔs we di intafɛs nɔ mach.

Multimode vs. Single-Mode: Wan Divays De Sɔpɔt Ɔl tu

Multimode fiber (MMF) ɛn single-mode fiber (SMF) na tu difrɛn kayn fayv. MMF gɛt tik kɔr (50 ɔ 62.5μm), i de sɔpɔt bɔku transmishɔn mɔd, i de rich shɔt (tipikli insay 2km), ɛn i de yuz 850nm ɔ 1300nm. SMF gɛt tina kɔr (9μm), i de sɔpɔt wan transmishɔn mɔd nɔmɔ, i de rich lɔng (we go rich 80km+), ɛn i de yuz 1310nm ɔ 1550nm.

Di PK56A siriɔs sɔpɔt ɔl tu di MMF ɛn SMF tɛst — na 850nm ɛn 1300nm档位 fɔ MMF, ɛn na 1310nm, 1490nm, 1550nm, 1610nm, ɛn 1625nm档位 fɔ SMF. Dis min se fil injinia dɛn nɔ nid sɛpret divays fɔ MMF ɛn SMF.

Insay prɔsis, di MMF ɛn SMF tɛst wokflɔ na di sem — pik di kɔrɛkt wevlɛnj档位, kɔnɛkt di fayv, rid di pawa valyu. Bɔt notis: MMF tɛst tipikli yuz 850nm (bikɔs MM sistem dɛn fɔs yuz 850nm VCSEL sɔs), we SMF tɛst de yuz 1310nm ɔ 1550nm. We yu pik di rɔng wevlɛnj档位, i de mek yu rid difrɛn we.

PV Plant Fayba Tɛst: Wan Ɔverluk Aplikeshɔn Sɛnariɔ

Insay PV plant, fayv kɔmyunikeshɔn link dɛn de transmit invɛrta ɔpreshɔnal data to di sɛntral monitarin sistɛm. If wan fayv link intarap, di monitarin sistem nɔ go ebul fɔ gɛt invɛrta data — we min se di PV plant ɔpreshɔn tim nɔ go ebul fɔ no us invɛrta gɛt prɔblɛm, wetin na di pawa autput, ɔ if efyushɔn na nɔmal. Fɔ 100MW PV plant we gɛt pɔtɛnɛshɛl ɔndrɛd invɛrta, if ɔl di fayba link dɛn intarap, di ɔpreshɔn tim fɔ trɔbulshut invɛrta bay invɛrta, pan bɔku bɔku kɔst.

PV plant fayba link dεm de fes yunik envayroment chalenj dεm. Fɔs: ay ambiɛnt tɛmpracha — dɛn kin bil PV plant dɛn na opin eria, wit sɔm tɛmpracha na grɔn we pas 60°C, ɛn fayv kin mek dɛn ol kwik kwik wan we dɛn gɛt ay tɛmpracha. sεkכn: UV εksposhכn — di polyεsta bכfa layεr fכ di fayv de dכn כnda UV rεdyushכn, we de mek di fayv dεm de brok.

So, dɛn fɔ put PV plant fayba tɛst insay di rɛgyula mentenɛns plan. We dɛn de aksept nyu plant, tɛst ɛvri fayv link in transmit pawa, gɛt pawa, ɛn link lɔs.

Di PK56A siriɔs in wayd-tɛmpracha dizayn (-10°C to +50°C) de mek i fayn fɔ ay-tɛmpracha PV plant ɛnvayrɔmɛnt.

Praktikal Advays: Fɔ Establish Standart Fayba Tɛst Wokflɔ

Fɔ injinɛri tim ɛn mentenɛns tim, mek standad fayba tɛst wokflɔ. Di wokflɔ fɔ inklud: pri-tɛst pripiamɛnt (kɔnfɛm wɛvlɛnj档位, inspɛkt ɛnd-fes klin, kɔnfɔm adapt tayp), tɛst ɛgzikishɔn (transmit pawa → risiv pawa → lɔs kɔlkyulɛshɔn → rɛd layt verifyeshɔn → ɛnd-fes fɔtografi), post-tɛst rikodin (data arkiv, anomaly mak, ripɔt jenɛreshɔn).

Di kor fɔ standad na dat tɛst data fɔ ‘di sem link, na di sem wevlɛnj, na di sem tɛm pɔynt’ na kɔmparabl. If di wevlɛnj档位 difrɛn, di ɛnd-fes klin difrɛn, ɛn di tɛm we dɛn de tɛst difrɛn akɔdin to di tɛst dɛn, dɛn nɔ go ebul fɔ yuz di data fɔ analisis di tren.

Fɔ di wan dɛn we de bay, if divays yuz sɛnɛriɔ kɔba bɔku fayba tayp ɛn bɔku intafɛs, prayoritayz OPM dɛn wit mɔlti-wevlɛnj ɛn mɔlti-intafɛs sɔpɔt.
