GaoTek Hot Sell Factory Price Passive DCM Module for Long Haul Data and CATV Transmission

Description

Overview

The GaoTek In long-distance transmissions, self-phase modulation (CSO) and fiber dispersion are problems that high-power analog optical transmission systems, particularly those operating at 1550 nm wavelength, must contend with. Self-phase modulation, fiber dispersion, and laser spectral width are the main causes of CSO degradation. Dispersion compensation fiber (DCF) and linear chirped fiber grating (CFG) are frequently used to address these problems. These methods’ high insertion loss, low dispersion ability, and small core diameter make them unsuitable for high-power HFC network transmission. DCM modules, as passive parts with a broad spectrum, have been used in networks successfully and produced positive outcomes.

Features

• For optical G652 single mode fiber in transmission links, a dispersion compensating module is used.
• Enhancements to the CSO performance of lengthy fiber-optic links.
• Low PMD and extremely low insertion loss.
• Self-phase modulation, fiber dispersion, and laser spectral width are the main causes of CSO degradation in high-power analog optical transmission systems operating at 1550 nm wavelength.
• Dispersion compensation fiber (DCF) and linear chirped fiber grating (CFG) are commonly used to address these problems but have limitations in high-power HFC network transmission due to their high insertion loss, low dispersion ability, and small core diameter.
• DCM modules have been successfully utilized as passive components with a broad spectrum in networks, yielding positive outcomes.
