  2. WDM & Optical Multiplexing in a Nutshell

    Optical Multiplexing Introduction

    In recent years Fiber Optic communication technologies have evolved at a rapid pace in order to support our increasingly data driven society. Many of the advancements have been in the area of finding clever ways to increase the transmission capacity of the existing fiber network infrastructure. Since multiplexing is a useful technique to accomplish this, researchers have explored optimizing optical multiplexing in time (TDM), space (SMX) , polarization or phase (PDM) and wavelength (WDM).

    WDM (Wavelength-Division Multiplexing)

    While some of the aforementioned multiplexing techniques (in particular spatial Multiplexing) hold great promise for future applications, this article focuses primarily on Wavelength-Division Multiplexing (WDM) as it is the most widely used by's applications, solutions and customers. In Essence WDM creates virtual fiber pathways over a single fiber strand by combining 2 or more wavelengths

  3. MTP Fiber Connector Guide

    What is an MTP Fiber Connector?

    MTP® is an acronym for Multi-fiber Termination Push-on and is the standardized terminating end of a multi-fiber cable that supports for all practical intents and purposes up to 24 fiber strands per connector. The MTP fiber connector is an improved, proprietary version of the standard MPO (Multi-Fiber Push-On) connector in respect to attenuation and reflection, yet uses the same form-factor and multiplex push-pul coupling type (SNAP). Developed by US Conec, the MTP connector increases overall performance by implementing structural improvements and higher quality materials.

    The ferrule is same as MT (Mechanical Transfer) but is more easily reconnectable.  Over time and under load, an MPO connector may show performance degradation and may compromise reliable transmission of high performance signals. Manufacturing improvements of its structural components have led to reduced insertion losses which will not change excessively under possible temperature fluctuations due to high amounts of traffic and a secure reliable connection can be maintained. The MTP optical connector is fully compliant with the MPO standard and therefore fully backwards compatible and capable of intermating with any MPO related equipment. For additional information, see the difference between MTP and MPO Connectors post.

  5. MTP Fiber Cable Guide

    MTP Fiber Cable introduction

    An MTP cable is essentially a multi-strand fiber optic cable terminated with high performance MTP® or MTP Elite® connectors on one or multiple ends. Depending on application and compatibility, different styles  of MTP fiber cable assemblies can be identified and rudimentary categorized into: MTP trunk cables, MTP extension harnesses and MTP breakout cables featuring up to 24 fibers per connector and 144 fiber strands per assembly. The MTP fiber cable, basically being an improved MPO fiber cable, meets and exceeds all of the MPO specifications yet provides full compatibility with MPO equipment and accessories. In order to maintain performance, it is recommended to use similar components to avoid complications such as an MTP-MTP connection. Visit our MTP Fiber Connector guide for more information.
