A.4 Diagrams
The diagrams in Figure A.1 and Figure A.2 are representative examples for the block diagram
of the RoF transceiver and the interface/reference points compliant with ITU-T G-Series
Recommendations – Supplement 55, respectively.
Figure A.1 also shows the internal functional block diagram of the RoF transmitter. The RoF
transmitter consists of 7 functional blocks and processes 4 main signals. The data signal is
transferred to the electrical interface, converted into an optical signal by the laser diode and
laser diode driver, and then transmitted through the optical interface. The power supply
provides power to the entire RoF transmitter to perform the defined function. The control
signal transfers a command for controlling the laser diode driver and the laser diode from the

– 12 – IEC 62149-10:2018 © IEC 2018
control function unit. Finally, the operation status information of the laser diode is transferred
to the monitoring function unit.
Figure A.1 also shows the internal functional block diagram of the RoF receiver. The RoF
receiver consists of 7 functional blocks and processes 4 main signals. The transmitted optical
signal is input to the optical interface, converted into an electric signal by the RF amplifier via
the photodiode, and then transmitted as an electric signal through the electric interface. The
power supply unit provides power to the entire RoF receiver to perform the defined function.
The control function unit transfers a command for controlling the RF amplifier. Finally, the
operation status information of the photodiode and RF amplifier is transferred to the
monitoring function unit.
Figure A.1 – Block diagram of RoF transceiver
Figure A.2 shows RoF system architecture. The RoF system mainly consists of the RoF OLT,
the RoF ONU and the ODN. The RoF OLT is commonly located at the central office and is
directly connected to one or more BBU. The basic function of RoF OLT is to convert radio
signals to optical signals and vice versa. Generally, the BBU is the baseband processing unit
of the mobile communication system; it is also located in the central office and connected with
the RRH via the RoF system, including the RoF OLT, ODN, and RoF ONU. In particular, a
single RoF OLT is able to accommodate multiple BBUs to make more efficient use of the ODN.
The BBUs are linked with the service provider's core network to offer various mobile Internet
services to users. The RoF ODN uses an optical fibre as a transmission medium and an
optical splitter to provide multiple connections between the RoF OLT and RoF ONUs. The
RoF ONUs are usually placed in remote sites and linked with one or more RRH. Like the RoF
OLT, the RoF ONU is also capable of turning optical signals into radio signals and vice versa.
The RRH contains the base station's RF circuitry and frequency up/down converter function.
Typically, each RRH has plural antennae equipped with a high-power amplifier and low-noise
amplifier for supporting a multi-input multi-output (MIMO) configuration. The interface S is the
point on the optical fibre just after the RoF OLT (downstream) / RoF ONU (upstream) optical
connection point (i.e. optical connector or optical splice). The interface R is the point on the
optical fibre just before the RoF ONU (downstream) / RoF OLT (upstream) optical connection

point (i.e. optical connector or optical splice). The RoF ONU has a UNI, and the RoF OLT has
an SNI. The choice of interface (SNI/UNI) depends on which services are provided by the
service operator. Reference point-1 and reference point-2 are utilized to define the
transmitted signal type and allowable signal delay or latency within the whole RoF system.

A.5 Labelling
It is recommended that each transceiver (and supporting documentation) be labelled in a
manner visible to the user with the following data at the minimum:
a) this specification reference, including variant type;
b) applicable safety warnings.
Labelling requirements for class 1 lasers are given in the laser safety standards referenced in
6.2.
A.6 Testing
A.6.1 General
