Balun G.703 E1/T1 – E3/T3 75-120 Ohms CUBITEL . DIN1.6/5.6 and BNC.

Cubitel is specialized in BALUN solutions and products providing a wide range of related products and a be-spoke (customization) design and assembly service to supply and cover any customer need. BALUN solutions efficient and reliable from single mini-balun to 19” panels with dual coaxial connectors (BNC or 1.6/5.6) to twisted pair RJ45 (RJ48) specially design for telecom carriers.

Dual compact Balun adaptor G703 75-120Ohm

Compact and very flexible solution that allows the impedance matching needed to connect equipment or lines from coaxial (75Ohm) to equipment or circuits over twisted pair (120Ohm). These adapters come with 2 interfaces in coaxial side for transmission (TX) and reception (RX) signals over twisted pair bidirectional. Especially useful for conversion/reception of carrier lines (coaxial) to twisted pair cable on customer side.

Available in different versions: BNC connectors, DIN 1.6/5.6 (Siemens) with whatever coaxial patchcord you may need to connect onto your equipment.


Transmision: G.703

Speed: 2 Mbps, 8 Mbps, 34 Mbps

75 Ohm Connector: Dual BNC or Dual 1.6/5.6

120Ohm Connector: RJ48 (female RJ45 shielded)

Dimmensions: 48 X 42 X 21 milímetros.

Cisco impedance matching (balun) solutions:

CAB-ADPT-75120 or CAB-E1-RJ45BNC

Using or kit-balun solution with the exact patch cords either in DIN, twinax or BNC format is an Cisco compatible with references CAB-APDT-75120 or CAB-E1-RJ45BNC but with the advantage of having a bespoke solution according to your actual scenario needs in terms of legth, gender or connector format.


Cubitel balun panels starts with our awarded 16-Ports balun panel 120-to-75Ohm 1U format 19” available for BNC and DIN 1.6/5.6 coaxial connectors (32 coaxial connectors per panel, 16 E1/E3 circuits). Available, of course with all pre-made cable you may need for an easy and safe deployment.

This panel will allow you to implement an impedance-matching connection up to 16 circuits (32 coaxial lines) to 16 twisted pair connections in 1U 19” only.

It complies with international G.703 specifications and it is a modular solution allowing you to insert or pull-out each balun individually. Again, the Cubitel Balun Panels range tries to cover all your needs and demands offering you a be-spoke design service for your specific communications scenario.
