NE1000 CATV Optical Transmitter Operation and Maintenance Guide
TROUBLE SHOOTING
Troubles Possible Cause and Solution
The AC Power LED is not lit and
the module does not work.
The fuse located on the rear panel is not intact. To
check this fuse, first power down the NE 1000 and then
remove the fuse from the transmitter. If the fuse is bad
then replace the fuse with a good 250V/3.15A fuse.
After new fuse is installed, then power up the NE 1000.
The optical output power is low.
1. Check to make sure the connector that is connected to
the NE 1000 is the same cut as is specified for the
transmitter. (The standard NE1000 is intended for use
with an APC optical connector.
2. Make sure the fiber connector end surface is clean.
3. Check the power supply AC voltage. This voltage must
not be less than 90 volts.
