1.0 PRODUCT SUMMARY The MX862R-2 CATV Fiber Optic receivers are designed high reliability with optical AGC, high level RF output, ease of use, easy to read LED indicators, and suitable for high-level applications. 2.0 INSTALLATION 2.1 Unpacking Inspect the shipping boxes for any obvious damages. Unpack the unit from all packaging boxes. Inspect the appearance of the unit for any shipping damages. Document and inform the shipping company and your local representative, as seen in section 1.
2.4 Optic connection 1. For your protection & safety, all the fiber optic connectors need protective covers during transportation. In order to ensure the insertion loss & return loss, the end-face of the fiber optic connector is polished. Connector should be clean. Dust will affect the transmission quality. When not using the fiber optic connector, please place the protection cover over the connector. Clean all fiber patch cords before connecting to the receiver.
Receiver Controls, Indicators, and Alarms This section of the manual will give an overview of the available menus in the MX862R-2 series optic receiver and their descriptions. All instructions in Section 2.0 refer to the representation of the front panel shown in the diagram below. The user scrolls through the menus using the push bottoms found on the front panel, these are located just to the right of the LCD screen. 3.1 The operation of the panel 3.1.1 Open menu A. Plug in 110V power supply B.
Menu # 3 - UNIT TEMP Read-only menu, indicates the system temperature Menu # 4 - RF LVL Read-only menu, indicates the RF input level Menu # 5 - RF MODE Current RF mode, display AGC/Manual If it appears RF Mode = AGC, while it was in the state of AGC If it appears RF Mode = Manual, while it was in the state of MGC Menu # 6 - +5V Reads Read-only menu, display the voltage +5V Menu # 7 - -5V Reads Read-only menu, display the voltage -5V Menu # 8 - +24V Reads Read-only menu, display the voltage +24V Menu # 9 - I
4.0 A. ANNOUNCEMENTS Received power: the received power should be between -12~+2dBm (1- to 0 is optimal), received power too low also may continue to operate, but CNR will rapidly deteriorate. Received power too high will cause CTB, CSO deterioration. When received power>3dBm(2mW) may damage optical receive module. B. RF output level: optical receiver’s RF output level related to receive power and optical receiver’s RF drive level (that is modulation coefficient).
5.0 1. ERROR AND REMEDY No RF output a) Check the power supply of the unit to determine whether it is normal. b) Insert optical connector, if the RX-Low is showing a red light, or no optical power, you should use an optical power meter to measure the optical power of the optical cable output connector.
