  • Optical modules are divided into direct modulation and external modulation

    Optical modules are divided into direct modulation and external modulation

    Optical modulation techniques which modulate parameters of lightwaves are categorized into direct modulation and external modulation. Direct and external modulation are primarily used in the optical domain with LED and Laser devices as methods for converting electrical data into optical. Definition: Optical Modulation is the process by which a light wave is modulated (modified) according to a high-frequency electrical signal that contains information. These modified light waves are then transmitted either by a transparent medium or through an optical fiber cable. Direct modulation is directly performed on an optical source, which is usually a light-emitting diode (LED) or a laser, without using a separate optical modulator.


  • Direct modulation of optical modules

    Direct modulation of optical modules

    Direct modulation is a technique in optical communication where the drive current of a laser diode is directly varied to encode information onto the optical carrier. When discussing optical transceiver parameters, modulation schemes are a key consideration, and the transmitter modulation method is specified in the datasheet of some optical modules, as shown in the figures below: • The transmitter laser modulation mode is marked as EML in the Moduletek 25G ER. In the introduction of product parameters of optical modules, we often mention the modulation mode as a key indicator, DML (Directly Modulation Laser) and EML (External Modulation Laser) are two major modulation technologies for optical modules. Its primary function is to achieve optoelectronic conversion by converting electrical signals into optical signals and vice versa.


  • Detailed Steps for Direct Fiber Optic Cable Fusion

    Detailed Steps for Direct Fiber Optic Cable Fusion

    Don't Miss this Super-Detailed Tutorial on Fiber Splicing and Winding! The operation and skills of fiber optic fusion splicing technology can be mainly divided into five steps: fiber stripping, fiber cutting, fiber melting, fiber sleeve, and fiber winding. See the FOA Virtual Hands-On for the process of fiber optic cable splicing (PDF). Fusion splicing is the most widely used method of splicing as it provides for the lowest loss and least reflectance, as well as providing the strongest and most reliable joint between two fibers. In this guide, you will find a chronological description of the fusion splicing process, the principal technical standards, and answers to the real-life questions network engineers and procurement teams may have.
