Optical Fiber
Apr 2017
NORCROSS, Ga., April 21, 2017 — OFS Fitel LLC has announced higher density wavelength division multiplexing capacity over its TeraWave ULL Optical Fiber with the Nokia Commercial Ultra-Wideband C+L-Band System, helping to reduce cost-per-bit of transport across the ultra-long-haul distances needed to connect hyper-scale datacenters.

The TeraWave ULL Optical Fiber has the largest available effective area for a terrestrial fiber, allowing maximum suppression of non-linear penalties that limit the reach of high-capacity, coherent modulation formats. The cost-per-bit of fully lighting a TeraWave ULL Optical Fiber can be up to 50 percent lower than the cost-per-bit of fully lighting a G.652 fiber by avoiding the high cost of regeneration to meet reach targets.

The TeraWave ULL ITU-T G.654.E Optical Fiber reduces amplifier noise by its ultralow nominal loss of 0.168 dB/km and minimizes non-linear distortion by its large effective area of 125 μm². The waveguide of the TeraWave ULL Optical Fiber was designed to minimize both microbending and macrobending losses in the L-band for good terrestrial cable performance and excellent splice performance.
