Abstract: An example method includes receiving radio frequency (RF) signals from a cable modem termination system (CMTS) in a small form factor pluggable optical transmitter; converting the RF signals to optical signals in the small form factor pluggable optical transmitter; and transmitting, by the small form factor pluggable optical transmitter, the optical signals on a network. More specific embodiments can include RF signals that are modulated, where a modulation error ratio (MER) of the RF signal varies substantially linearly with Carrier to Composite Noise (CCN), and the converting is implemented by a laser transmitter. Other, more specific, embodiments include routing the RF signals through a pre-distortion RF amplifier RF variable attenuator, and coupling the optical transmitter to a chassis of the CMTS.

Abstract: Disclosed herein are embodiments of a device, method of use and system for an analog multi-wavelength transamplifier. The transamplifier embodiments described herein allow the use of multiple wavelengths to segment logical service groups, such as for use in a CATV distribution system and a FTTH system having a broadband overlay. Improved optical signal power performance can be achieved by using direct modulating transmitters and maintaining polarization of the optical signals that are modulated by a phase modulator, such as an external waveguide.

Abstract: The present invention is directed towards systems and methods that include an optical polarization scrambler or depolarizer after the optical transmitter. In this manner, the optical signal is depolarized. Accordingly, the noise peaks that were translated from Guided Acoustic-Wave Brillouin Scattering (GAWBS) by the devices with polarization dependent loss or gain is mitigated in order to have little effect on the quality of the RF signal carried by lightwave.
