Siemon adds armored OM3 and OM4 fiber cable assemblies to 40-/100 Gb/s MTP-based line

Dec. 1, 2011
Siemon says its armored cable offers 7X the crush resistance of standard fiber to protect high-performance channels, eliminating the need for fiber ducting, while cutting material and labor costs by up to 50%.

Siemon has added multiple armored cable options to its line of high-performance MTP-based plug and play fiber cable assemblies. Available in 40Gb/s and 100Gb/s-capable OM3 and OM4 multimode fiber cable constructions as well as standard 62.5/125 and 50/125 multimode and singlemode, the new plug and play assemblies feature flexible, spiral wrapped aluminum interlocking armor offering over 7X the crush resistance of standard assemblies, according to the company.

According to the company, this added durability supports rugged-environment intrabuilding backbone and horizontal installations and eliminates the need for ducting to protect non-armored fiber cable. Compared to the installation of non-armored fiber with separate innerduct or conduit, the use of armored cable can cut installation costs by up to 50% or more for both materials and labor, contends Siemon.

Available in 12 to 144 fiber counts in increments of 12 fibers and in custom lengths, the armored plug and play fiber cable assemblies are user-configurable to precise application requirements. Constructed of high-quality fiber optic cable and components for future-proof support of critical links up to 40Gb/s and 100 Gb/s application speeds, the system's factory terminated and tested connections guarantee maximum channel throughput without the performance variability of field terminations.

In both armored and non-armored varieties, Siemon OM3 and OM4 multimode MTP assemblies have passed independent third-party testing by Experior Labs, confirming 40Gb/s and 100Gb/s-readiness and performance margins in accordance with the latest IEC 1280-4-1 Edition 2 and TIA/EIA-455-171A standard. These latest IEC and TIA/EIA testing procedures use new Encircled Flux methods, which limit the negative impact on the accuracy of multimode fiber Insertion Loss and Return Loss test results.

Encircled flux compliance reduces test variability by up to 75% versus the previous test methods, helping eliminate false pass results that can degrade overall network performance. The more accurate encircled flux test methods indicated industry-leading performance margins of up to 60% for all Siemon product tested.

To ensure these high performance levels are maintained in every plug and play assembly , Siemon notes that it performs 100% automated end-face inspection of all fiber interfaces to IEC 61300-3-30 Ed 1.0 to limit contaminants and surface defects that significantly degrade system performance. Siemon also tests all of its plug and play assemblies for Insertion Loss and Return Loss in both directions for both 850n and 1300nm wavelengths and ships individual test results with every assembly.

The full Siemon plug and play fiber optic system includes low-profile MTP to LC or SC modules, MTP pass-through adapter plates and an extensive offering of pre-terminated MTP to MTP, and MTP to LC cable assemblies.
