E1/ G.703 Coax to Twisted Pair Adapter (Balun)
CY460F CY460MC CY460F
1.0 GENERAL INFORMATION
Thank you for your purchase of this Sakertele Electronics product, CY460 Series allow 75Ωcoax hardware to communicate with 120Ω twisted pair equipment. The CY460 Series specifically address the ONP requirement that European PTTsoffer 120 Ohm twisted pair terminations to their customers. The sign also output by them are scaled to match the pulse shape requirements specified by the CCITT G.703/E1 standard.
CY460 is a Dual Coax to RJ45 Balun Adapter which realize 75 Ohm coax to 120 Ohm RJ45 impedance converter.
