AllWave ULL (Ultra Low Loss) Single-mode Optical Fiber is an Ultra Low Loss ITU-T G.652B and ITU-T G.654.C compliant fiber designed for terrestrial optical networks.
With a 9.2µm Mode-field diameter, AllWave ULL is compatible, including low splice loss, to the embedded base of standard single-mode fiber.
Ultra low loss fiber can provide additional optical margin beyond G.652.D fibers, enabling longer amplifier span lengths, increased site distances, ultimately decreasing overall network cost while improving performance.
This fiber supports longer un-amplified and un-regenerated reach and greater optical power margins in comparison to standard single-mode fibers and improve the performance over C- and L-band systems.
AllWave ULL supports all of the major optical amplifier types, including EDFA, Raman, and hybrid amplification to help system designers and service providers.
Following is an example comparison of number of spans possible with a given fiber type, assumptions: BER FEC Limit : 1.0e-3 , Modulation format : PM-16QAM, Baud rate : 64 Gbaud, # of channels : 9, EDFA NF : 5.0 dB
