XTENDR™ HFC Repeater

Lindsay’s XTENDR HFC repeater is designed for easy extensions of existing HFC networks. The XTENDR device provides a suitable migration path and cost-effective connection of customers in rural areas using fiber optics without overbuilding the coaxial footprint of the HFC plant.

The XTENDR device includes a forward optical transmitter with an optional optical amplifier providing high output power to convert downstream RF signals to optical, and reverse optical receivers to convert upstream optical signals to RF. Customers that previously could not be reached with the traditional HFC network can now be served by using the HFC repeater in combination with Lindsay’s LBON series of mini RFoG nodes at the customer premise.

Up to 16 rural subscribers can be reached within a distance of 20 km (65,000’/ 12.5 mi) using this device. Many other designs can be implemented to serve up to 32 rural subscribers from a single device. 

The return receivers in the device are DOCSIS® 3.1 capable, up to 204 MHz upstream bandwidth, wideband (1240 nm to 1620 nm; except 1540-1560 nm) multi diode receivers. Available diplex filter splits are 42/54, 85/102 or 204/258 MHz. The maximum downstream bandwidth is 1218 MHz.

The XTENDR device can be mounted on a strand or a pole and is outdoor-rated for operation from -40°C to +60°C (-40°F to +140°F). The device comes in an IP65 outdoor-rated housing and can be powered locally through a dedicated powering port, or remotely by combining power on the RF port with 40-90 VAC HFC power. Power consumption is less than 18 watts.

Lindsay offers end-to-end solutions for extending your existing HFC network including designing your network using our XTENDR HFC repeater, optical passives, and RFoG CPEs.
