ORC 1000 F Compact node for Fiber To The Curb 

Description 

The compact node ORC 1000 F is specially designed for reception and amplification of 

signals at Fiber To The Curb locations, situated at the end of the optical net. The receiver 

has one optical input, the amplifier is provided with two outputs by means of a splitter. The 

nominal output level is 2x100 dBµV. The automatic gain control plug in module regulates on 

a pilot signal at 80.6 MHz and keeps the output level constant with variation in optical input 

power. An optical AGC also keeps the output level constant with variation in optical input 

power. The desired output levels are set by means of plug-in modules. RF output 1 and the 

return path output are provided with test sockets. The return path has an output to supply 

signal to the separate return path transmitter. 

Housing is made of die-cast aluminium and offers protection according to IP54. This type of 

housing guarantees optimal heat dissipation and perfect protection of the electronic 

components. 

Features 

Output splitter included for symmetrical outputs. No additional logistics are needed. 

Single output selectable by means of 0 db plug-in. 

The plug-in modules (PIM..) for attenuation and equalization can be changed without 

service interruption. 

Soft-clipping hybrid, protecting content. 

Full balanced pre- and return path amplifier, reducing second order products. 

No power consumption in returnpath amplifier with passive return path. 

Ultra-high efficiency switch mode power supply (> 88%). 

Indicator for DC and AC supply voltages enabling fast diagnosis. 

Power factor corrector which reduces power loss in feeding-net by 75% (I²R). 

Ceramic capacitors in switch mode power supply secondary site, significantly 

improving lifetime, reliability and EMI. 

Only electrolytic capacitor on input site, stress protected by PFC.
