Marka hore, aqoonta aasaasiga ah ee moduleka indhaha
1.Qeexid:
Module indhaha: taasi waa, moduleka transceiver indhaha.
2.Qaabka:
Module transceiver-ka indhaha waxa uu ka kooban yahay qalab optoelectronic ah, wareeg shaqaynaysa iyo indho-indheyn, aaladda optoelectronic waxa ay ka kooban tahay laba qaybood: gudbinta iyo helitaanka.
Qaybta gudbinta waa: signal koronto gelinaya heerka kood gaar ah waxa farsameeyaa chip wadista gudaha si loo kaxeeyo laser semiconductor (LD) ama diode iftiimiya (LED) si ay u sii dayso calaamada laydhka ee la habeeyey ee heerka u dhigma, iyo indhaha indhaha. korantada koontaroolka tooska ah ayaa gudaha lagu bixiyaa.Awoodda ishaarada indhaha ee wax soo saarka ayaa weli ah mid deggan.
Qaybta helaysa waa: module gelinta signalka indhaha ee heerka koodhka qaarkood waxa loo beddelaa signalka korantada ee diode sawirqaade.Ka dib preamplifier-ka, calaamada korantada ee heerka koodhka u dhigma ayaa soo baxaysa, calaamada wax soo saarkuna guud ahaan waa heerka PECL.Isla mar ahaantaana, qaylo-dhaanta alaarmiga ayaa soo baxaysa ka dib marka takhaatiirta indhaha la gelinayo ay ka yaraato qiimo gaar ah.
3.xuduudaha iyo muhiimada moduleka indhaha
Qaybaha indhaha ayaa leh cabbiro farsamo oo badan oo optoelectronic muhiim ah.Si kastaba ha ahaatee, labada qaybood ee kulaylaha ah ee la isku beddeli karo, GBIC iyo SFP, saddexdan cabbir ee soo socda ayaa aad uga walaacsan marka la dooranayo:
(1) Mawjada dhexe
Nanometers (nm), hadda waxa jira saddex nooc oo waaweyn:
850nm (MM, multimode, qiimo jaban laakiin fogaanta gudbinta gaaban, guud ahaan kaliya 500M);1310nm (SM, hal hab, khasaaro weyn inta lagu jiro gudbinta laakiin kala firdhisan yar, guud ahaan loo isticmaalo gudbinta gudahood 40KM);
1550nm (SM, hal hab, khasaare yar inta lagu guda jiro gudbinta laakiin kala firidhsan weyn, guud ahaan loo isticmaalo gudbinta fogfog ee ka sarreeya 40KM, oo si toos ah u gudbin kara 120KM iyada oo aan gudbin);
(2) Heerka gudbinta
Tirada bits (bits) ee xogta la gudbiyo ilbiriqsi kasta, bps.
Hadda waxa jira afar nooc oo inta badan la isticmaalo: 155 Mbps, 1.25 Gbps, 2.5 Gbps, 10 Gbps, iyo wixii la mid ah.Heerka gudbintu guud ahaan waa dib u socon kara.Sidaa darteed, 155M moduleka indhaha waxaa sidoo kale loo yaqaan FE (100 Mbps) moduleka indhaha, iyo 1.25G moduleka indhaha waxaa sidoo kale loo yaqaan GE (Gigabit) moduleka indhaha.
Kani waa moduleka loogu isticmaalka badan yahay qalabka gudbinta indhaha.Intaa waxaa dheer, heerka gudbinta ee nidaamka kaydinta fiber (SAN) waa 2Gbps, 4Gbps iyo 8Gbps.
(3) Fogaanta gudbinta
Calaamadaha indhaha uma baahna in lagu sii gudbiyo fogaan si toos ah loo gudbin karo, kiiloomitir (sidoo kale loo yaqaan kiiloomitir, km).Qaybaha indhaha guud ahaan waxay leeyihiin tilmaamo soo socda: multimode 550m, hal qaab 15km, 40km, 80km, iyo 120km, iyo wixii la mid ah.
