Description

F-MININODE Fiber to the Home Mini Node


The F-MININODE is an HFC return path transmitter and RF optical reciever for use in fiber to the home applications. The unit has 45-870MHz RF outputs for digital TV as well as an optional optical transmitter for the 5-45MHz cable modem return path.  We carry two fiber units as well as WDM single fiber units. The F-MININODE has many applications in Hybrid Fiber Coax systems and for Fiber to the home applications. This is a compact and highly reliable unit for use with analog, digital video, and bi-directional data transmission in HFC networks.

Thor has a dedicated team for FTTx applications. Every Fiber Optic cable system is different.  We can provide a wide variety of OLT and ONU units to meet your FTTx and GPON needs. Contact a sales engineer today for help in determining what equipment is needed for your fiber optic system.

Features

 •  Excellent linearity and flatness
 •  Extremely good return loss
 •  Compact construction, lower power consumption
 •  WDM option to achieve single fiber bi-directional transmission
 •  Multi-communications transmitting wavelength and power optional

IMPORTANT NOTE*** (it is very important to interface our unit with SC/APC - Angle Polished Connector to avoid any light reflections.

If your fiber is terminated with the  SC, ST, FC /PC flat connector, you need to use an optical jumper from PC type to SC/APC for proper conversion. 

Model Selection

 • F-MININODE-1RT   Receiver and Return Path Transmitter over single fiber

 • F-MININODE-2RT   Receiver and Return Path Transmitter over 2 fibers
