ORT 1000 F Compact node for WKC and Fiber To The Curb

ORT 1000 F Compact node for WKC and Fiber To The Curb 

Description 

The optical receiver/transmitter ORT 1000 F is specially designed for reception and 

amplification of signals at WKC and Fiber To The Curb locations. The receiver has one 

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

output level is 1x108/2x104 dBµV. Also available is a lower level AUX in/output. The 

integrated automatic gain control regulates on a pilot signal at 80.6 MHz. 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. All RF in- and outputs are provided with test 

sockets. 

For transmitting return path signals the unit can be equipped with a plug-in laser module. The 

transmitter has two electrical inputs and one optical output. The laser is a double isolated 

DFB, CWDM or DWDM type. Filters for 15, 65 and 27 MHz are configurable. 

An optional plug-in HMS compliant management system provides amongst others the 

possibility to control the upstream level. 

Housing is made of die-cast aluminium and offers protection according to IP52. This type of 

housing guarantees optimal heat dissipation and perfect protection of the electronic 

components.

Features 

Ingress-safe output splitter included for symmetrical outputs. No additional logistics 

are needed. Single output selectable by means of shifting the module one pin to the 

right. 

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. 

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

Indicator for DC and AC supply voltages enabling fast diagnosis. 

Ceramic capacitors in switch mode power supply secondary site, significantly 

improving lifetime, reliability and EMI.
