G.703 Balun Panel (75-Ohm L9 (DIN1.6/5.6) to 120-Ohm RJ-45) for modular 19' rack mount's


AN-IC16 G.703 rack mount balun panel lets you match the connectors, impedance and signal characteristics of up to 16 dual coax L9 (DIN1.6/5.6) connections (75 ohm) with up to 16 twisted pair connections (120 ohm). Operating in compliance with the CCITT G.703 specification, the AN-IC16 occupies only 2U (3.5″/8.9 cm) of vertical rack space in a 19″ (48.3 cm) rack-allowing for efficient multiport matching.

L9 (DIN1.6/5.6) connectos, used in this series AN-IC16-L9 balun panels are screw coupling miniature coaxial connectors, which are developed and manufactured according to specification of IEC169-13, CECC 22240 and DIN 47295. They have the characteristics of small size, high mechanical and electrical stability and used in many types of communication equipments.
