75 ohm to 120 ohm balun converter G703 fiberhome ZTE SDH E1 DDF panel

Product Overview

Description

 

    The term BALUN (pronounced "bal-un") is derived from the function of the passive device that converts between a BALanced and UNbalanced electrical signal. Common types of baluns convert 100 Ohm twisted pair (balanced) to 75 Ohm coaxial (unbalanced). 

 

      HT BALUN-1/16/24-XX-XX family 75 to 120 Ohm BALUN provide IDC-BALUN, single port Box BALUN, 8/16/24 ports 19 inch Rack Mount BALUN. 

 

    HWATEL Balance-Unbalance converter totally comply with EUROPE USA standard. And OEM for many Europe, USA, Japan and Taiwan partner, such as CISCO, Alcatel (Shanghai), HUAWEI, ZTE, UT-starcom, Fiberhome, D-link, ADC, CTC, NEC, Comtech, advantech. 

 

    

 

     More HWATEL provide compatible accessory which connect between BALUN and DDF , such as CISCO, HUAWEI, ZTE standard E1 Coaxial Cable patch cord, T type DDF connector , E1 cable.
