System and method for facilitating fiber access transport using pluggable radio frequency optics |
摘要 |
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. |

1. A method comprising:
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, wherein a modulation error ratio (MER) of the RF signal varies in a substantially linear fashion with Carrier to Composite Noise (CCN); and transmitting, by the small form factor pluggable optical transmitter, the optical signals on a network.
