RM465 E1 19″英寸2U機(jī)架式16路阻抗匹配器75-120歐姆
RM465是19″2U高多功能機(jī)架式16路G.703平衡到非平衡轉(zhuǎn)換器，它不僅能解決傳統(tǒng)的16路雙銅軸到雙絞線之間的信號(hào)轉(zhuǎn)換器，而且還可實(shí)現(xiàn)50-Pin(DB50/RJ48M)口到雙同軸之間的信號(hào)轉(zhuǎn)換。使用RM465用戶只需使用普通120Ω雙絞線或DB50線纜就能完成75Ω同軸硬件的信號(hào)通信。
性能特點(diǎn)：
★ 符合ITU/CCITT G.703建議標(biāo)準(zhǔn)
★ 完成BNC（75Ω）到RJ45（120Ω）雙向信號(hào)轉(zhuǎn)換
★ 完成BNC（75Ω）到DB50（120Ω）雙向信號(hào)轉(zhuǎn)換
★ 網(wǎng)絡(luò)速率：2.048Mbps
★ 鏈路到數(shù)據(jù)隔離電壓1000V DC/AC
★ 75Ω接頭：雙同軸接口BNC，母頭或公頭
★ 120Ω接頭：RJ-45、RJ48M（DB50）
★ 電源供電：無需外加電源或電池供電
★ 外形尺寸：48.3W × 8.9H × 10.2D (cm )

SAKERTELE CY460F/CY460MC/RM465
E1/ G.703 Coax to Twisted Pair Adapter (Balun)
CY460F CY460MC CY460F RM465
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.
