Basic Function: It is mainly used to realize the data transmission function in the base station system, ensuring the stable and reliable signal transmission between the baseband processing unit (BBU) and other devices.
Electrical Characteristics: The input voltage is generally 36VDC - 60VDC, and the input current is ≤ 100A. The output voltage is 36VDC - 60VDC, and the output current of each channel is ≤ 18A (total current 100A).
Physical Characteristics
- Cable Type: It is an optical cable with 4 cores, including white/green and yellow/brown groups, which are respectively connected to the DDF 2M interface through the head. It can also be directly connected to the DDF 2M interface using a network cable through a 75 - ohm to 120 - ohm converter.
- Length: Usually, it is available in standard lengths of 5m and 15m, such as the FTBC - 0120 - 05m and FTBC - 0120 - 15m models, to meet different installation environment requirements.
Technical Specifications
- Transmission Rate: It supports multiple transmission rates to adapt to different network standards, such as GSM, LTE, etc., meeting the requirements of different service data transmission in the base station system.
- Transmission Protocol: It follows relevant communication protocol standards, such as supporting [specific protocol], ensuring effective data interaction and communication with other devices in the base station system.
Environmental Adaptability: It can work normally within a wide temperature range of - 40℃ to + 70℃, adapting to different outdoor environmental conditions. The supported humidity range is generally 5% - 95% (non - condensing), ensuring reliable operation in various humid or dry environments.
Application Scenarios: It is widely used in Nokia's base station equipment, such as Flexi - edge series base stations. It is an important part of the base station transmission system, ensuring the normal operation of the base station and the stable transmission of data.
