Fiber Optic Testing and Certification (OTDR)

  

Fiber optics cabling is the core of today's Datacom networks. Optical fiber is the predominant media type for mission-critical datacenter links, backbone within buildings, and longer distances for campus networks. As network speeds and bandwidth demands increase, distance and loss limitations have decreased, making fiber optic cabling certification more important than ever. For decades, fiber optics have been inspected and cleaned to ensure the proper passage of light. While fiber optics inspection and cleaning fiber connectors is not new, it is growing in importance as links with increasingly higher data rates are driving decreasingly small loss budgets. With less tolerance for overall light loss, the attenuation through adapters must be lower than ever before. This can be achieved by properly inspecting and cleaning fiber optic cables when they are installed or while making moves, or changes.

Certification of new cabling per IEEE, TIA/EIA, or ISO/IEC standards is necessary to ensure that the link will run the intended application. Complete fiber optic cabling certification includes two parts; Tier 1 or Basic Test Regimen and Tier 2 or Extended Test Regimen. Tier 1 fiber optic cabling certification is performed with a power meter and light source or optical loss test set such as the OptiFiber OF-500 to measure the absolute loss of the link and compare it to the limits in the standard. Tier 2 fiber optic cabling certification and troubleshooting can be performed with an OTDR such as the OptiFiber Pro OTDR.

Certification of fiber optic links requires the right testing equipment, detailed knowledge of installation and application standards, and the ability to document your test results. The OptiFiber is a handheld fiber optic certification tester that quickly and easily certifies multi-modeand single-mode networks. One button measures fiber length and optical loss on two fibers at two wavelengths, computes the optical loss budget, compares the results to the selected industry standard and provides an instant PASS or FAIL indication.

Network Cabling

These extra levels of detail are part of the reason why there can be such a variance in cabling installation costs.  Many customers mistakenly presume that "cabling is cabling" and hire non-qualified, or lowest-cost personnel, without the proper tools or training to install sensitive network infrastructure.  Data infrastructure requires entirely different installation processes than electrical or simple telephone wiring, and we believe that we provide a superior solution that allows the customer to not worry about their cabling infrastructure once it's been installed.

                              


Network Cabling - Testing and Certification

Many people "install" network cabling, but fail to actually test and certify it.  There is a difference.  Simply installing cabling and then running a "tester" on it is not the same as certifying that the voice and data cabling will actually meet the rated speed that you're paying for.  Devices may light up at both ends of the connection, but how do you really know that you're getting 100Mb, and maybe not 10Mb?  When network problems arise, do you really want to have to worry about the wiring being suspect?

VNS Testing and Certification Reports

Because of the demanding requirements of today's network infrastructure, the only true way to confirm that your cable infrastructure actually meets the specifications and quality level that you've purchased is to test and certify it.  We test and certify all twisted-pair cabling for Category 5/5e/6 compliance (where applicable), including continuity, proper polarity, crossed-pairs, NEXT, and shorts with an industry-standard Fluke DTX Level IV cable certifier, or equivalent.  We also test and certify all our fiber optic cabling installations.  Once Attach Communications completes an infrastructure installation, you can be assured that your physical infrastructure meets the specs that you paid for.  We also maintain an archive copy of your cable/fiber scans on site, so that they can be provided in the future if you've lost your copy.

Our voice and data cabling technicians are certified too.  We do not hire the lowest cost personnel that we can find or subcontract our work out to someone else.  We look for high quality, professional, trained and certified full-time employees, and then continue to train them to stay abreast of the latest industry standards and performance requirements from BICSI,       EIA/TIA, â€‹CompTIA, etc.  We take great pride in the high quality of the workmanship that we provide and we back it up with a Lifetime Workmanship Warranty.

Voice Cabling

Customers often ask what the differences are between the various types of cable (Cat3, Cat5, Cat6).  In one Word, the higher the number, the better the performance, and accordingly, the higher the price tag.  The most common types of cabling are Category 3 (used primarily for voice today), Category 5 and 5E (the most common type of cabling, used for both voice and data, and also supports Gigabit Ethernet), and Category 6 and 6A.  Customers sometimes request Category 6 because they think it's a requirement for Gigabit Ethernet, which isn't quite correct.  Gigabit Ethernet can run on Category 5 cabling, however, Category 6 will perform better.  The key is the bandwidth the cable supports. 

Category 6 is rated at 550Mhz (and the newest Category 6a specifies 1000Mhz), whereas Category 5E is rated at 350Mhz.  The higher megahertz support allows cabling to handle the greater amount of noise and crosstalk that occurs on a wire when faster (ie: gigabit and 10G) connections are running on that wire.  When signals are run at a higher frequency that the cabling is not rated for, it can cause errors and anomalies.

So what are the cost variances?  Generally speaking, you can expect to pay a 20% price premium between Cat6 and Cat5E, and a 50% price premium between Cat 5E and Cat 6a.
