Description
HY-21-R40 optical node is a compact in-door optical node especially designs for FTTH application. It designs with a single MMIC chip, compared with the two-stage amplifier structure, it has the characteristics of high integration, high performance, excellent anti-jamming performance. In addition, it can achieve best linearity and low noise figure with lowest power consumption by power saving sill. It also achieves digital AGC control skill by I2C interface. It provides a high-quality and high-performance FTTH network solution for cable TV operators.
Feature
