It is a 1 port 75 Ohm BNC E1 to 120 Ohm RJ45 balun impedance convertor, plastic casing. 75Ohm/120Ohm E1 Balun Converter (Balance to Unbalance Converter)

75Ohm/120Ohm 1E1 Balun Converter (Balance to Unbalance)

SPOTLIGHT:It is a 1 port 75 Ohm to 120 Ohm impedance convertor, plastic casing.Description:75/120 Ohm impedance matching baluns allow users to use inexpensive shielded twisted pair cabling in place of expensive coaxial cabling. Especially useful in telecommunication applications for patching at the distribution frame. Units meet CCITT Recommendation G703 and are great for American or European applications.Supporting E1 data rates to 2.048 Mbps, the balun receives 75 ohm signals and converts them to 120 ohm for transmission over a network or reception by a CPE. The signals output by theare scaled to match the pulse shape requirements specified by the CCITT G.703 standard. The balun can perform 120 ohm to 75 ohm signal conversion as well, giving the device a dual role.Features:Data Rates to 2.048 Mbps 75 Ohm Dual Coax to 120 Ohm Twisted Pair Bi-Directional Signal Conversion No AC Power or Batteries Needed Male or Female Coax BNC Connectors Available Ultra-Miniature Enclosure SpecificationsTransmission Line: CCITT G.703 (unstructured) Data Rate: 2.048 Mbps75 Ohm Connection: Dual coax BNC connectors, male or female (RG 59 or 2002 coax)120 Ohm Connection: Shielded RJ-45 jack (standard) or External Terminal BlockPower Supply: none requiredLink-to-Data Isolation: 500 volts AC/DCOperating Temperature: 0° to 50°C (32° to 122°F) Dimensions: 2.7" (6.86 cm) L x 1.7" (4.32 cm) W x 0.8" (2.03 cm) DTypical Application:
