4E1 PDH Fiber Multiplexer JHA-CPE4

(19 inch 1U Type)

Mwachidule

Chipangizochi chimapereka mawonekedwe a 1-4* E1 , Waya wa 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

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, chepetsani kukonza mzere
• 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.
