Transceiver Optical waa aalad u beddesha calaamadaha E1 badan oo u beddela calaamadaha indhaha.Transceiver indhaha waxaa sidoo kale loo yaqaan qalabka gudbinta indhaha.Transceivers indhaha waxay leeyihiin qiimo kala duwan marka loo eego tirada E1 (taas oo ah, 2M) dekedaha la kala qaado.Guud ahaan, transceiver-ka ugu yar wuxuu gudbin karaa 4 E1s.Transceiver-ka ugu weyn ee hadda jira wuxuu gudbin karaa 4032 E1s, E1 kastana waxaa ku jira 30 taleefan.Haddaba, waa maxay macnaha transceiver indhaha 2m, iyo waa maxay xidhiidhka ka dhexeeya transceiver indhaha E1 iyo 2M?

Noocyada transceivers indhaha, transceivers indhaha waxaa loo qaybiyaa 3 qaybood: PDH, SPDH, SDH.transceivers indhaha PDH waa transceivers indhaha oo yar-yar, guud ahaan loo isticmaalo labo-labo, loo yaqaan codsiyada dhibic-ilaa-point, iyo awoodoodu guud ahaan waa 4E1, 8E1, iyo 16E1.Transceiver indhaha SDH waxa uu leeyahay awood weyn, guud ahaan 16E1 ilaa 4032 E1, SPDH transceiver indhaha, inta u dhaxaysa PDH iyo SDH.Guud ahaan marka la hadlo, transceiver indhaha ayaa ka badan transceiver indhaha PDH, kaas oo ah qalab beddelka photoelectric.Guud ahaan, transceiver indhaha oo leh hal deked indhaha ah iyo afar dekedood oo koronto ah oo 2M ah ayaa ugu badan.Hawl-wadeennada isgaadhsiinta ayaa inta badan u isticmaala gudbinta calaamadaha codka.Xafiiska dhexe, terminaalka indhaha ayaa u beddela signalka korantada ee 2M oo u gudbiya fiilada indhaha.Kadib marka la gaaro dhamaadka isticmaalaha, ishaarka indhaha waxaa loo rogaa calaamad koronto oo 2M ah, taas oo ah, adeegga 2M waxaa loo diraa qalabka codka sida PCM.Fiber optic transceivers ayaa aad loogu isticmaalaa isgaarsiinta xogta.Sidoo kale waa nooc ka mid ah qalabka beddelka korontadu.Guud ahaan, waxaa jira in ka badan hal deked indhaha ah iyo dhowr dekedood oo Ethernet ah.Waxay u beddeshaa calaamadaha indhaha calaamadaha Ethernet, kuwaas oo loo isticmaalo in loogu diro adeegyada xogta qalabka isgaarsiinta xogta sida router ama furayaasha.

Wixii transceivers indhaha, 2M asal ahaan ka dhigan tahay in 1550 ee ugu dambeeya ee mawjada uu leeyahay 2M bandwidth, kaas oo loo isticmaalo in lagu gudbiyo 485 xogta gacanta, iyo waxaa jira 1.25G, 155M iyo wixii la mid ah, taas oo ah bandwidth looga baahan yahay gudbinta video, asal ahaan 1 channel of video ah. u baahan 155M.Transceivers indhaha E1 iyo 2M ​​dhab ahaantii kaliya way ku kala duwan yihiin muujinta.E1 waa muujinta kooxda ee heerka Yurub ee PDH (oo u dhiganta kooxda heerka Waqooyiga Ameerika waa T1, ie 1.5M).Heerka E1 heerka Yurub waa 2M, markaa 2M waxaa badanaa loo isticmaalaa in lagu matalo E1.Waxa kale oo la odhan karaa E1 waa magaca sayniska iyo 2M ​​waa magaca guud.Xilligii SDH, heerka VC12 (iyo TU-12) ee xidhiidhka isku dhufashada ee SDH wuxuu ku dhowaa 2M (dhab ahaantii ma 2048K), dadka qaar ayaa sidoo kale u yaqaan kuwan 2M, taas oo run ahaantii aan sax ahayn.Dekadda E1 ee aaladda, waxaa guud ahaan loo yaqaan dekedda 2M, waana inay noqotaa E1 codkar si ay u noqoto mid sax ah.Si la mid ah, dekedda 34M waa inay noqotaa dekedda E3, dekedda 45M waa inay noqotaa dekedda DS3.140M dekedda waa E4.
