CHAPTER 1: OPERATION NOTICE
OPERATION NOTICE
1. Operation Notice
ATX Networks strongly advises you to read the following safety instructions prior to installing and operating this equipment.
1. The transmitter should have a good grounding with a grounding resistance<4Ω.
2. The machine utilizes a high performance, high reliability, and steady voltage switching power supply. It has constant
voltage overflow protection and can work in 110~240 VAC electrical networks. The micro-processor monitors the
output DC voltage.
3. In order to make sure reflection loss is =45dB, use APC style connectors; other types (such as SC/PC) are not
designed to mate with the QFCT1310 APC style optical connector. Keep the connector clean when installing.
4. Do not activate the transmitter without the fiber cable attached or without the fiber output port covered. Harmful laser
radiation is emitted which can cause harm, especially to the eyes.
5. RF level determines the OMI of the laser and the system index (CNR, CTB, CSO). When at 59 route PAL-D, its RF
level is 20dBmV. Suppose channel is N: Si(N)=20+10Lg(59/N) (dBmV)
6. CNR and Channel N: CNR(N)=CNR(59)+10Lg(59/N) (dB)
