China yogulitsa 1+1 Fiber Back-Up Pdh - 4E1 PDH Fiber Multiplexer JHA-CPE4m - JHA

4E1 PDH Fiber Multiplexer JHA-CPE4m

Mwachidule

Chipangizochi chimapereka mawonekedwe a 1-4* E1 , telefoni yamawaya ya Standard 2 ngati engineering order-waya (posankha). Imasinthasintha kwambiri. Ili ndi ntchito ya alamu. Ntchitoyi ndi yodalirika, yokhazikika, komanso yotsika mphamvu yogwiritsira ntchito mphamvu, kuphatikiza kwakukulu, kukula kochepa.

Chithunzi cha malonda

75 ohm Back Panel

120 ohm Back Panel

Mawonekedwe

• Kutengera kudzikonda kwa IC
• Modular wide dynamic Optical detector
• Amagwiritsa ntchito matelefoni amtundu 2 (zotengera zosagwirizana ndi foni) zokhazikitsidwa ngati mainjiniya oyitanitsa-waya hotline(posankha)
• Mawonekedwe a E1 amagwirizana ndi G.703, amatengera kuchira kwa wotchi ya digito komanso ukadaulo wosavuta wa loko
• Chizindikiro cha kuwala chikatayika, chimatha kuzindikira kuti chipangizo chakutali chazimitsidwa kapena ulusi walumikizidwa, ndikuwonetsa alamu ndi LED.
• Chipangizo chapafupi chikhoza kuwona momwe chipangizo chakutali chikugwira ntchito
• Perekani lamulo la mawonekedwe akutali Loop Back, chotsani kukonza mizere
• Mtunda wotumizira ndi 2-120Km popanda kusokoneza
• AC 220V, DC-48V, DC+24V ikhoza kukhala yosankha
• DC-48V/DC+24V magetsi okhala ndi ntchito yodziwikiratu polarity, ikayikidwa popanda kusiyanitsa pakati pa zabwino ndi zoyipa.
