Fiber Services

Our fiber services include fiber characterization testing – Campus and Data Centers, OSP and CWDM & DWDM.

Fiber ServicesFiber Characterization Services

Fiber characterization is a comprehensive set of measurements performed on a fiber optic cable link to determine the key performance attributes of that link. Our fiber optic characterization service enables you to have a true representation of your network’s capabilities.

Customers often ask us when they should have fiber optic characterization performed. We try to provide the simplest answer possible – anytime you have a link that is running at 10 Gbps or faster. Remember that each time a system gets upgraded to a faster delivery speed, the optical thresholds for that fiber system become more stringent. Links running speeds of 10 Gbps or higher should be considered high performance and high value links. Most links running at these speeds are subject to Service Level Agreements (SLA) which mandate the network up time and performance required. Fiber characterization is required for high-speed links such as 10 Gig, 40 Gig and DWDM networks to ensure that signal integrity is not affected by ORL, CD and PMD.


Fiber Characterization Testing:

Campus (premises cabling – LAN, short runs) & OSP (outside plant – WAN, long haul)

  • Tier 1 = Insertion Loss, length
  • Tier 2 = ORL and OTDR trace

OSP (outside plant – long haul)

  • CD – Chromatic Dispersion
  • PMD – Polarization Mode Dispersion
  • AP – Attenuation Profile


  • Commissioning and Trouble-shooting

Data Centers and Campus

  • BERT – Bit Error Rate Test
  • Layer 2 – Mac-in-Mac
  • Layer 3
  • Layer 4 – 10GE TCP Line Rate
  • Layer 4 – TCP/UDP
  • SAN – 1 to 10G Fiber Channel
  • OTU2 OTN 11.2G Overclocking
  • IP Video
  • Multiple Streams
  • Ethernet – RFC 2544
