RU General Specications
Item Specication
Interface ▪ Optical interface x1 for ORAN (10G SFP)
• SFPs are changeable in the eld.
• Cascading of RU is not supported.
▪ ANT port x 4 (4.3-10 RF connectors)
Warning: Avoid excessive power input to prevent RU damage. e maximum absolute input level of the Rx
port is +3.5 dBm (5 minute max) based on 3GPP in-band blocking specications.
Avertissement: Évitez une alimentation électrique excessive pour éviter d'endommager RU. Le niveau
d'entrée absolu maximal du port Rx est de +3,5 dBm (5 minutes maximum) sur la base des spécications de
blocage dans la bande 3GPP.
▪ RET (AISG 8-pin circular connector conforming to IEC 60130-9 - Ed. 3.0 with screw-ring lock.)
▪ LED (For indication of RU status, green: normal condition, red: failure. e eCPRI condition indicator)
▪ Debug/Test port (RJ45 supports 100Base-T or 1GE. Only for manufacturing use.
▪ Power connector (Amphe-BTS connector series or compatible connector is used. 2 wire (–48 V DC, Return))
▪ 6AWG FG (M6 bolts x 2), 0.625 mm hole spacing
Optical bit rate 10.3125 Gb/s

Measurement Function
Item Specication
VSWR alarm reporting e RU supports Voltage Standing Wave Radio (VSWR) alarm reporting on all external TX RF connections by
measuring the TX RF-signal return loss.
e VSWR is less than 1.5 for each port under all operating and environmental conditions. When VSWR at any
port exceeds 1.5, the RU reports an alarm to the EMS and the RU stops transmit power in order to protect the
RU from damage. e alarm indicates which port has exceeded the VSWR requirement. Refer to RU Alarms.
Noise oor measurement e RU supports the function of measuring the Received Total Wideband Power (RTWP), when initiated by
EMS or when initiated by the DU.
