Kingtone JIMTOM® B8+B3+B1 +40dBm Fiber Optical Repeater Remote Unit, KT-F-L8L3L1-P40-B datasheet
Overview
The remote unit of the multi-band, multi-operator fibre coverage system. It takes the combined signal from the master unit over fibre and delivers it as RF into the in-building antenna system. The model name carries the +40 dBm figure; the datasheet output power row reads +33 ± 2 dBm per band, so the two are not the same quantity and we quote the datasheet figure.
- Aluminium cast cabinet design
- Wide band design covering 698–3700 MHz, with B8, B3 and B1 in one unit
- Time delay of 1 µs or less — short enough for the round trip not to matter
- Noise figure ≤ 6 dB
- Waterproof design for all-weather installation
- Spectrum mask per 3GPP TS 38.143 (NR) and TS 36.143 (LTE)
- Local and remote monitoring optional, with automatic fault alarm and remote control

Indicators are based on ETSI standard testing. Availability varies depending on the laws and regulations of each country. Unless otherwise specified, all displayed specifications are typical and subject to change without prior notice.
- The model name carries +40 dBm but the datasheet output power row reads +33 ± 2 dBm per band. The two are not the same quantity — the model name likely refers to a different configuration or a total figure. Quote the datasheet value and confirm with us before committing to +40 dBm in writing.
- The datasheet does not state an environmental class (IP rating); the IP66 figure comes from the product team, not from the datasheet.
Where our documents disagree with each other, we show both readings and confirm the value for your variant before you order. Tell us the model and band you need.
Certification status for this model is not recorded in this library. Do not state that it is certified without checking the certificate; ask us for the specific model number when you need the certificate.
