4E1 PDH Fiber Multiplexer (Desktop)
Astaamaha
*Iyada oo ku salaysan is-copyright IC
* Modular wide dynamic optical detector
Waxay isticmaashaa heerka caadiga ah ee 2 teleefoonka siliga ah (gacanta aan taleefoonka ahayn) oo loo dejiyay sidii injineernimo khadka taleefanka dalbashada (ikhtiyaar)
* Interface E1 wuxuu u hogaansamaa G.703, wuxuu qaataa soo kabashada saacada dhijitaalka ah iyo tignoolajiyada qufulka fudud
*Marka isha ishaadu lunto, waxay ogaan kartaa in aaladda fog ay dansan tahay ama fiber-ka uu go'ay, waxayna ku tusaysaa digniinta LED-ka
*Qalabka maxaliga ahi waxa uu eegi karaa qalabka fog ee xaalada shaqo
* Bixi amar interface-ka fog Loop Back, dayactirka khadka fudud
* Fogaanta gudbinta ayaa ah ilaa 2-120Km iyadoon kala goyn
* AC 220V, DC-48V, DC+24V waxay noqon kartaa ikhtiyaar
* DC-48V/DC+24V koronto leh shaqo ogaanshaha polarity otomaatig ah, marka la rakibo iyada oo aan la kala saarin togan iyo taban
Halbeegyada
*Fiber
