Enhanced Multimode Fibers Reduce Attenuation, Improve Connectivity Performance in Data Centers

LAS VEGAS, Sept. 16, 2013 /PRNewswire/ -- BICSI Fall Conference, Booth 306 -- OFS, a leading designer, manufacturer and supplier of innovative fiber optic network products, today announced it has improved several important optical and geometry specifications for its line of 50 micron multimode fibers including LaserWave® FLEX bend-optimized fiber.

The new, tighter specifications can reduce connector loss and improve link system performance in cabled fiber for demanding data center and enterprise applications. The enhancements can provide extra margin, or "headroom," in 10, 40 and 100 Gb/s applications, enabling greater network design flexibility and reliability.

For its line of 50 micron multimode fibers meeting the OM4, OM3 and OM2 standards, OFS has lowered its 850 nm attenuation specification from less than or equal to 2.3 dB/km to less than or equal to 2.2 dB/km, the lowest in the industry.  This improvement will help fiber-optic cablers minimize attenuation in their cable and provide end users with low-loss links in their networks.

In addition, OFS has improved several key geometry specifications in its 50 micron multimode fibers to industry-leading levels. Clad diameter tolerance has been tightened from 125.0 plus or minus 1.0 mm to 125.0 plus or minus 0.8 mm, while clad non-circularity has been improved from 1% to 0.7%. Combined with a numerical aperture tolerance that has been tightened from 0.200 plus or minus .015 to 0.200 plus or minus .010, these improved specifications allow for better core-to-core alignment and light-coupling efficiency in connectors and splices, thereby helping to reduce the loss at these connections.

Modeling of simulated connections conducted by OFS indicates that the tighter specifications can result in connection loss improvement approaching 0.1 dB per connection. In a common worst-case, 4-connection link, this would result in an improvement of nearly 0.5 dB, a significant improvement in light of the fact that total multimode loss budgets are shrinking below 2.0 dB for 40 and 100 Gb/s speeds.

OFS is able to realize these improvements through the use of its patented Modified Chemical Vapor Deposition (MCVD) fiber manufacturing process. This process is optimally suited for creating the precision refractive index profiles required for today's high performance laser-optimized multimode fiber, like LaserWave FLEX OM4/OM3 Fibers, capable of transmitting to distances of 550 meters at 10 Gb/s, and 150 meters at 40 and 100 Gb/s.
