In #1 (contact to ground) Aux. In #2 (contact to ground) Aux. In #3 (contact to ground) Aux. Out #1 (open collector) Aux. Out #2 (open collector) Aux.
Headend to Remote Interconnections 3.2 Headend to Remote Interconnects The single mode fiber optic interconnections between the Headend and Remote modules are to be made in whatever manner suits the system configuration. For the CAN Network connections please refer to DCM000000103. 3.3 Fiber Optic Connections 3-4 • All Fiber Optic Cabling must use 9/125 or similar Single-Mode (yellow jacketed) highquality cable. This cable should typically have less than 0.
Chapter 4 Remote Module 4 Introduction This chapter contains specifications and information for the LinkNet Uniserv Unit RF-FIBER Remote Modules. 4.1 Power for the Remote Module The US remote module may be powered by any source of negative ground +28VDC power capable of delivering 1 Ampere. This includes the optional single US remote module US-PS01 power supply. 4.2 Battery Backup of Remote Module If the US remote module is being used without a battery it must be configured to NOT use a battery.
Module Specifications 4.3 Module Specifications Table 2 Module Specifications Frequency Bands Maximum Downlink Power Maximum Uplink Power Combined at any Headend RF Output. Includes the 4-way combiner loss.
Remote Module Per-Carrier Derating 4.4 Remote Module Per-Carrier Derating All signals that fall within a given Pass-Band range will “share” power amongst them. A multiple channel effect is intermodulation, signals produced from non-linear effects between the intended channel signals. This intermodulation may cause interference to receiving equipment. In order to minimize intermodulation signals, power de-rating must be applied.
