FiberTTP fiber optic cable infrastructure services
            TTP offers a full range of fiber optic cable (FOC) infrastructure services including installation of gigabit passive optical networks (GPON), testing/troubleshooting, characterization, maintenance, and optical link mapping.

fiber1Installation
            Whether you need fiber installed in your building or outside of your building, TTP has the expertise, tools, and equipment to support your requirements.  We design/construct/install outside plant (OSP) pathways including setting maintenance holes (MHs), hand holes (HHs), and vaults, and installing conduit between them.  We also have the capability to install fiber in OSP pathways.  Once installed, our expert fiber technicians can terminate and/or splice, and test the fiber.

TESTERTesting/troubleshooting 
            TTP has a full complement of trained technicians and calibrated OTDRs and power meters to successfully support any FOC testing or troubleshooting requirement.  We also do third party fiber testing.

WIRESFiber characterization
            Fiber characterization involves the testing of new or existing FOC to determine its capability to meet the performance standards for multiple wavelength, high speed services (e.g., 10G, 40G, 100G).  TTP will perform multiple tests (i.e., optical insertion loss (OIL), optical return loss (ORL), chromatic dispersion (CD), polarization mode dispersion (PMD)) on designated spans of fiber and provide results that show individual fiber characteristics and limitations.

wires1Maintenance
            Existing FOC infrastructure requires a maintenance program to ensure that fiber is operating at its highest potential.  TTP can clean and inspect all fiber connections and evaluate the infrastructure in order to make recommendations that will allow optimization of the fiber network.

fiber2Optical link mapping (OLM)
            OLM involves an end-to-end assessment of each fiber link with event characterization and fiber status to allow prompt diagnosis of fiber network issues.

Fiber Characterization

Fiber characterization involves the testing of new or existing fiber optic cable to determine its capability to meet the performance standards for multiple wavelength, high speed services (e.g., 10G, 40G, 100G).  TTP will perform multiple tests on designated spans of fiber to determine the quality and transmission capability of that fiber.  Specifically, these tests measure losses and dispersions.  TTP will then provide results that show individual fiber characteristics and limitations, and a determination if the fiber can meet the customer’s required performance standard.

Characterization tests
Before fiber characterization tests are conducted the TTP team will communicate with the customer to determine performance requirements.   We will then develop and provide a test plan for customer approval.  Once on site, we will commence testing to include the following:

  • Fiber connector and bulkhead inspection and cleaning
  • Calculation of a fiber link loss budget to determine the maximum optical insertion loss (OIL) then bi-directional testing to compare the calculated value to the testing values
  • Bi-directional testing to determine optical return loss (ORL)
  • OTDR testing to identify events in the fiber span, average losses for the events, and the span length
  • Chromatic Dispersion (CD) testing to determine the pulse spreading of different light waves
  • Polarization Mode Dispersion (PMD) testing to determine if there are any physical disorders of the fiber
  • Optical link mapping (OLM) – end-to-end assessment of each fiber link with event characterization and fiber status to allow prompt diagnosis of network issues
