Introduction

World Wide Packets LightningEdge® Coarse Wave Division Multiplexing (CWDM) solution presents service providers with a way to selectively increase the utilization of existing fiber assets to quickly deploy additional bandwidth and services at a fraction of the investment required to deploy new fiber.

10x Bandwidth Increase

World Wide Packets CWDM solution enables service providers to increase the useable bandwidth of existing fiber infrastructure by a factor of ten. All of the CWDM solution components fully conform to the ITU-T G.694.2 standard, which specifies eighteen optical wavelengths spaced 20 nm apart from 1270 nm to 1610 nm.

Current CWDM implementations only make use of the upper eight lambdas from 1470 nm to 1610 nm. The water peak at 1383 nm renders 1370 nm through 1410 nm unusable due to potential absorption of hydroxyl ions by the fiber, and the O- Band is typically already in service, however the 1430 nm and 1450 nm lambdas are very viable. In addition to the eight lambdas from 1470 nm to 1610 nm, World Wide Packets CWDM solution enables the use of the 1430 nm and 1450 nm lambdas, resulting in ten useable lambdas – a 10x increase in bandwidth as compared to existing fiber, and a 25% increase in bandwidth as compared to current CWDM implementations.
