4E1 PDH Fiber Multiplexer(Desktop)
Likaroloana
*E ipapisitse le boikemelo ba IC
* Modular wide dynamic Optical detector
*E sebelisa mohala o tloaelehileng oa 2 oa mohala (o se nang mohala) o behiloeng joalo ka mohala oa odara oa boenjiniere(ho ikhethela)
*E1 segokanyimmediamentsi sa sebolokigolo sa G.703, se amohela ho hlaphoheloa ha tshupanako ya dijithale le thekenoloji ya ho notlela mohato o boreledi
* Ha lets'oao la optical le lahlehile, le khona ho bona hore sesebelisoa se hole se koetsoe kapa faeba e khaotsoe, 'me e bontša alamo ka LED.
* Sesebelisoa sa lehae se ka bona boemo bo sebetsang ba sesebelisoa se hole
* Fana ka taelo ea sebopeho se hole sa Loop Back, nolofatsa tlhokomelo ea mohala
*Bohole ba phetisetso bo fihla ho 2-120Km ntle le tšitiso
*AC 220V, DC-48V, DC+24V e ka ba khetho
*Motlakase oa DC-48V/DC+24V o nang le ts'ebetso ea othomathike ea polarity, ha e kentsoe ntle le phapang lipakeng tsa botle le bobe.
