TWF (True Wave Fiber)

 

TWF, True Wave Fiber, True Wave Fiber. True wave fiber is optimized for wavelength window, dispersion and PMD characteristics, making it suitable for high bit rate DWDM transmission in the 1550 nm band.

 

True wave fiber


Optical fiber is the physical transmission medium of optical signals, and its characteristics directly affect the bandwidth and transmission distance of optical fiber transmission systems. Fibers with different characteristics have been developed to adapt to different applications.

The zero dispersion point is in the short wavelength region below 1530 nm. In the optical amplification region of 1530 to 1565 nm, the dispersion coefficient is 1.3 to 5.8 ps/nm.km. The system operates in the "positive region" of the dispersion of the fiber. In this region, the self-phase modulation effect SPM can compress the pulse width, thereby contributing to the reduction of the dispersion pressure.

The zero dispersion point of the true wave fiber is in the short wavelength region below 1530 nm, and the dispersion coefficient at 1549 nm to 1561 nm is 2.0-3.0 ps/nm. The zero dispersion point of the SMF-LSTM fiber is near 1570 nm in the long wavelength region. The system operates in the negative dispersion region and has a dispersion value of -1.5 ps/nm at 1545 nm. Km. The new G.655 fiber can expand the effective area to 1.5 to 2 times that of a typical fiber. The large effective area can reduce the power density and reduce the nonlinear effect of the fiber. A series of new communication single-mode fibers have been developed internationally, such as large-area non-zero dispersion-shifted single-mode fibers including Corning's LEAF and Lucent's TrueWaveXL, low dispersion slope fiber, TureWaveRS, and large effective area non-zero dispersion with reduced slope. Displaced single-mode fiber, dispersion-flattened non-zero dispersion-shifted single-mode fiber, and slope-compensated single-mode fiber.
