Paper Abstract

An ITU G.652.C-compliant low water peak (LWP) single-mode fiber used with low-cost, full-spectrum, coarse wavelength division multiplexing (CWDM) transmission system [ ] optimizes bandwidth and distance reach for moderate bandwidth, un-amplified, metro/access networks. In this work, we used low-cost active and passive full spectrum CWDM devices to achieve 16-channel error-free transmission (1310 nm - 1610 nm) at 2.5 Gb/s per channel over 50 km of LWP fiber. The aggregate capacity of 40 Gb/s is 33% greater than standard fibers with inherently higher attenuation at 1383 nm. At 50 km, ITU G.652-compliant standard single-mode fiber excessively attenuates the four channels between 1370 nm and 1430 nm. Additional testing utilizing Avalanche PhotoDiode (APD) receivers is demonstrated to extend the LWP fiber distance reach to nearly 70 km [ ] for all 16 channels between 1310 nm and 1610 nm. The transmission equipment included 16 un-cooled distributed-feedback (DFB) laser transceivers and a pair of 16-channel mux/demux modules. All 16 channels showed Q-factors (20logQ) exceeding 18 dB over 50 km of LWP fiber, corresponding to a BER well below 10-15. The standard single-mode fiber exhibited excess loss near 1383 nm, resulting in failure of three channels due to receiver shutdown, with a fourth channel performing at marginal operation with a bit error rate (BER) of 10-9. The dispersion power penalty was negligible for O-band (1260 nm - 1360 nm) channels, increasing to about 1 dB for L-band (1565 nm - 1625 nm) [ ] channels. Robust, error-free operation was achieved for ambient temperatures up to 50 °C for representative channels across the CWDM bands from 1310 nm to 1610 nm. These results demonstrate that a G.652.C, LWP fiber enables optimal transmission distance and optimizes low-cost transmission technology [4] for moderate bandwidth, un-amplified, metro/access networks through full-spectrum CWDM with an aggregate capacity of 40 Gb/s.
