Kingtone JIMTOM® B28+B8+B3+B1+WIFI+N78 +23dBm Fiber Optical Repeater Remote Unit 20260720 datasheet
Overview
The +23 dBm remote unit of the six-band multi-operator fibre coverage system. It converts the fibre signal back to RF at +23 dBm. This is the variant for small areas — a lift car, a small office, a corridor — where the antennas are connected directly to the remote unit and no passive distribution system is involved. The extruded aluminium profile chassis is only 58 mm deep, which is what makes it fit where a rack unit cannot.
- +23 dBm output, for small areas where antennas connect directly to the remote unit
- Six bands in one unit — B28, B8, B3, B1, WiFi 2.4 GHz and N78
- Extruded aluminium profile chassis, only 58 mm deep
- Time delay of 2 µs or less
- Wide band design covering 698–3700 MHz
- Low power consumption — 50 W total, excellent heat dissipation
- 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 datasheet's output power row is cut off after the WiFi entry, so the per-band output figures and the maximum gain are not quoted; the +23 dBm in the model code is the headline figure.
- 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.
