ITU/CCITT G.703 balun
Answer
G.703 is a CCITT* standard for transmitting voice over digital carriers such as T1 and E1.
G.703 provides the specifications for pulse code modulation (PCM) at data rates from 64 Kbps to 2.048 Mbps.
G.703 service is typically used for interconnecting data communications equipment such as bridges, routers, and multiplexers. G.703 is transported over balanced (120 ohm twisted pair) or unbalanced (dual 75 ohm coax) cable. Whether the G.703 is balanced or unbalanced depends on your geographic location and the carrier that supplies the service. Balanced service is the most common around the world with the exception of the U.K. and the Netherlands. However, the new Open Network Provision standard of the EEC requires that balanced service be available throughout all of Europe.
*CCITT: the CCITT (Consultative Committee on International Telegraphy and Telephony) former name of the ITU (International Telecommunications Union), is the primary international body for fostering cooperative standards for telecommunications equipment and systems. It is located in Geneva, Switzerland.

Answer
Balun are passive devices that provide the right interface between 2 different types of cabling systems. Usually, it is between coaxial and twisted pair cables.
In many communication systems, there are mis-matches in connector types and differences in impedance between equipments and cabling systems.
Our extensive line of Balun products include Single-port., Dual-port, mini Balun (fully shielded IDC type, Krone IDC and Toolless IDC) and keystone type for panel mounts, which support data transmission to meet CCITT G.703 recommendation.
Data speeds can be up to 155 Mbit/s and meet CCITT G.703 specification.
There are three speed versions as follows:
- 2-8 Mbit/s for E1/T1 and E2/T2 data streams
- 2-8-34 Mbit/s for E1/T1 to E3 data streams
- 34 to 155 Mbit/s for E3 and higher data streams.
The Balun enable unbalanced coaxial type 75 ohm transmit signals to connect easily to the Telecom Industry standard of 120 ohm (or 100ohm) twisted pair cables (E series 120 ohm, T series 100ohm)
Effective use of Balun will save you extra cost on expensive and space-consuming coax hardware without requiring any devices, ducts and additional space.
All our Balun are 100% test for reliability and durability to guarantee your signal integrity, and applicable both for American and European Telecommunication system.
