5.1. Inspecting the Product
Before installation, please first check the models and quantities of optical multiplexers and
accessories with the packing list. Also, please check whether the equipment is in perfect
condition. Occasionally, drying process may be needed if the equipment is affected with
damp environment.
5.2. Preparation Before Installation
The following steps are required before installing the optical multiplexers:
Please read the user manual carefully.
Prepare all the wires and cables that are needed. Make sure there is no reverse
connection, disconnection or short circuit connection. Refer to Appendix A for
details of cable making.
Make sure that the voltage of the power supply is within the tolerance range and the
chassis is grounded with the earth.
Prepare the bit-error-rate tester and optical power test-meter for the test of link
quality.
If using 120Ω balanced signal interface, please change the dip-switch setup on the
bottom of the optical multiplexer.
Fix the optical multiplexer into RC001-16 (19-inch 3U chassis). Pay attention to the
ambience requirement.
5.3. Installation
5.3.1. Connecting Data Interfaces
E1 interface
It is suggested to use cables provided in accessories.
Optical interface
Insert the SC fiber tail into the optical interface (push hard until to the end). If you are not
sure about transmission direction, it's advised to connect the fiber cable after applying the
power supply.
5.3.2. Applying Power Supply
Insert the module into the chassis and fix it with the screw at the bottom of the module.
If the power supply is DC –48V, please ground the PGND with the earth first, then "-48V"
pin with the lower voltage cable, "0V" pin with higher voltage cable before applying the
power supply. Make sure it is firmly fixed, and there's no reverse connection and no short
circuit before applying the power supply.
