- Qaladka TX waa wax soo saar furan/ururin, kaas oo ay tahay in lagu soo jiido 4.7K–10KΩ caabiyaha sabuuradda martida loo yahay.Soo jiid danab inta u dhaxaysa 2.0V iyo VccT, R+0.3V.Markay sareeyso, wax soo saarku wuxuu muujinayaa cillad laysarka nooc ka mid ah.Hooseeyo waxay muujinaysaa hawlgal caadi ah.Xaaladda hoose, wax soo saarka waxaa loo jiidi doonaa <0.8V.
- Disable TX waa gelinta loo isticmaalo in lagu damiyo wax soo saarka indhaha ee gudbiyaha.Waxa lagu soo jiiday moduleka dhexdiisa iyada oo leh 4.7-10 KΩ iska caabin ah.Dawladdiisu waa:
Hooseeyo (0 - 0.8V): Gudbiye shid
(> 0.8, <2.0V): Aan la qeexin
Sare (2.0 – 3.465V): Gudbiyaha waa naafo
Furan: gudbiye waa naafo
- Mod-Def 0,1,2.Kuwani waa biinanka qeexida moduleka.Waa in lagu soo jiid 4.7K – 10KΩ iska caabin ah oo saaran sabuuradda martida loo yahay.Korontada soo jiidantu waa inay noqotaa VccT ama VccR.
Mod-Def 0 waxaa saldhig u ah moduleka si loo muujiyo in cutubku jiro
Mod-Def 1 waa xariiqda saacada ee laba xidhiidhiye silig oo xidhiidhsan oo aqoonsi taxane ah
Mod-Def 2 waa xariiqda xogta ee labada xiriiriye ee silig ee aqoonsiga taxanaha ah
4. LOS (Loss of Signal) waa ururiye furan/wax soo saarka dareeraha, kaas oo lagu soo jiidi karo 4.7K – 10KΩ iska caabin ah.Soo jiid danab inta u dhaxaysa 2.0V iyo VccT, R+0.3V.Marka uu sareeyo, wax soo saarkan ayaa tilmaamaya in awoodda indhaha ee la helay ay ka hooseyso dareenka qaataha ugu daran (sida lagu qeexay heerka la isticmaalo).Hooseeyo waxay muujinaysaa hawlgal caadi ah.Xaaladda hoose, wax soo saarka waxaa loo jiidi doonaa <0.8V.
- VeeR iyo VeeT waxa laga yaabaa inay gudaha ugu xidhan yihiin moduleka SFP.
- RD-/+: Kuwani waa soo-saarka soo-dhoweynta ee kala duwan.Waxay DC ku lammaan yihiin 100Ω xariiqo kala duwan oo ay tahay in lagu joojiyo 100Ω (ka duwan) isticmaalaha SERDES.
- VccR iyo VccT waa aqbalaha iyo gudbiyaha sahayda korontada.Waxay ku qeexan yihiin 3.3V ± 5% marka la eego pin xiriiriyaha SFP.Sahayda ugu badan ee hadda jirta waa 450mA.Shaandhaynta sahayda korantada ee guddiga martida loo yahay ayaa lagu muujiyay hoos.Inductors leh iska caabbinta DC ee ka yar 1Ω waa in la isticmaalo si loo ilaaliyo tamarta loo baahan yahay ee pin-gelinta SFP oo leh 3.3V danab sahay ah.Marka shabkada shaandhaynta saadka ee lagu taliyay la isticmaalo, ku xidhidh kulul ee moduleka transceiver SFP waxa ay dhalinaysaa qulqulka hadda socda oo aan ka badnayn 30mA oo ka weyn qiimaha gobolka ee joogtada ah.VccR iyo VccT ayaa laga yaabaa inay gudaha ugu xidhan yihiin moduleka gudbinta SFP.
- TD-/+: Kuwani waa agabka gudbinta kala duwan.Waxay yihiin AC-ku-duuban, khadadka kala duwan oo leh 100Ω joojinta kala duwanaansho gudaha cutubka.Isku xirka AC waxaa lagu sameeyaa gudaha moduleka oo sidaas loogama baahna guddiga martida loo yahay.

GEPON OLT ee Codsiga P2MP
Guud ahaan
Transceiver HDV ZL5432099-ICS oo leh taageerada heerka xogta ee caadiga ah 1.25 Gbps ee codsiga GEPON OLT ilaa 20km fogaanta gudbinta, waxaa loogu talagalay inay la kulanto Shiinaha Telecom EPON qalabka farsamada ee shuruudaha V2.1 1000BASE-PX20+.Caymiska SC waxaa loogu talagalay is dhexgalka indhaha.
Module-ku waxa uu bixiyaa macluumaadka ogaanshaha dhijitaalka ah ee xaaladiisa hawleed iyo heerka uu marayo, oo ay ku jiraan gudbinta awooda, eexda laysarka, galinta awooda indhaha, heerkulka moduleka, iyo danab sahayda.Xogta xad-dhaafka ah ee cabbirka iyo qaylo-dhaanta/ digniinta waxay ku qoran yihiin oo lagu kaydiyaa xusuusta gudaha (EEPROM).Khariidadda xusuusta waxay ku habboon tahay SFF-8472, sida ku cad sawirka 2. Xogta ogaanshaha waa qiyamka A/D ceeriin waana in loo beddelaa unugyada dhabta ah ee adduunka iyadoo la adeegsanayo jaangooyooyinka cabbirka ee lagu kaydiyo goobaha EEPROM 56 - 95 ee A2h.
