Chapter 1 Product Introduction
1.1. Introduction
BD-2GPON-OEO is a ITU-T G.984.x & ITU-T G.988 standard-based GPON link amplifier developed
by Baudcom with independent intellectual property rights. It has good compatibility and fully adapts
to the mainstream OLT/ONU in the market. It can extend the coverage of GPON system from the
previous 20km to 50km or even further. GPON can be integrated with the mainstream OLT/ONU
manufacturers in the market, thus forming an efficient and flexible long-distance GPON solution.
BD-2GPON-OEO is an optical power amplifier for GPON lines developed by Baudcom. It uses OEO
mode to amplify and shape the signals, and achieves 3R amplification of the signals.
BD-2GPON-OEO can effectively amplify the optical power of PON lines and extend the transmission
distance of network. It has the features of compact structure and convenient installation. It can be
widely used in various fields such as GPON cell access, GPON fiber-to-the-home and so on.
To realize distance extension function of BD-2GPON-OEO PON link amplifier, the corresponding
logical distance of the OLT ports needs to be set. It can only be amplified within the range of the
logical distance and it does not allow exceeding the logical distance.

Chapter 2 BD-2GPON-OEO Application
2.1. Extend Transmission Distance
Figure 0-1 Extend Transmission Distance
The original link cannot reach the maximum transmission distance of OLT due to line attenuation and
other reasons. By using BD-2GPON-OEO device, the optical power can be enhanced to support the
transmission distance of 50km.
In theory, BD-2GPON-OEO should be placed before the splitter where the optical power of OLT
reaches its attenuation limit, so as to ensure sufficient optical power after splitting and further to
ensure long-distance transmission of PON network.
2.2. Increase Splitting Ratio
Figure 0-2 Increase Splitting Ratio

The original link can only support a splitting ratio of 1:64 due to splitting attenuation and other
reasons. By using BD-2GPON-OEO device, the optical power can be enhanced and the splitting
ratio can be extended to 1:128.

3.4. DC Power Cord Connection
The DC48V power cord is as shown in the figure below. One end is a green phoenix terminal
connector which is used to connect BD-2GPON-OEO device. The other end is two power cable
connectors which are used to connect the DC power supply. As shown in the figure below, the power
cable marked “RTN”is used to connect the DC positive pole and the power cable marked “N48V”is
used to connect the DC negative pole.
Please do not plug the electrified power cord.

If the equipment is planned to be installed in a 19-inch cabinet, please choose tray bracket. It is
recommended that BD-2GPON-OEO be fixed on the tray bracket before the equipment is mounting.
As shown in the figure below, two screws are used to fix the BD-2GPON-OEO equipment from the
side to the tray bracket.
Figure 0-5 Install BD-2GPON-OEO on Tray Bracket
Use cabinet screws to fix the tray bracket on the slot of 1U height, as shown in the figure below. Then
complete the mounting of the equipment.

Chapter 6 Precautions
6.1. Precautions
The optical fibers of the single board are straight out; please do not look directly at the core of the
optical module, so as to prevent laser from burning eyes.
6.2. Maintenance of Single Boards
Fault Location Method
In case that failure such as business interruption or optical power instability occurs, the following
steps are usually used to locate the fault:
1. Check and adjust the optical fiber connection. If the service returns to normal, the fault will be
solved. If the optical fiber connection is normal, please continue with the next step.
2. Check and adjust the input optical power of the local and the opposite ends of the single board. If
the service returns to normal, the fault will be solved. If the input optical power is normal, please
continue with the next step.
3. Equipment failure, please replace the equipment.
