LightEdge Series

FXC LightEdge series will easily be able to build a high-speed metroarea backbone that expands over the existing optical infrastructure.

The LightEdge series is compact and therefore requires little rack space, and uses very low power. The data stream can be transmitted bi-directionally over a single fiber. The system design provides a scalable and flexible architecture. In addition, laser safety is built-in with an efficient management protocol that is ideal for the metro area.

FXC Inc. has excellent optical transmission engineering based upon many patents and provides a WDM solution, which is easy to install and to manage for adaptable construction of the metropolitan area transmission infrastructure in the era of broadband.

LightEdge5000 SeriesLightEdge5000 Series
LightEdge5000, 8ch high-end CWDM system, offers carrier grade solutions to meet diverse needs of users putting premium on transmission quality. Compact size - 1U/1.5U/2U, multiplexing 1ch up to 8ch, supporting Ring topology.

New Functions
-Out-Band / Inline monitoring
  Optical Supervisory Channel (OSC) is equipped. Independent wavelengths (1430 & 1450nm) are assigned for supervision only. Both data and monitoring signal can be accommodated on the uniform network.
-Path protection
  Redundant configuration at local side is supported. Working path will be changed over to stand-by path immediately in case LM’s LOS, failure and LM inadvertently unmounted are detected.
-Performance monitoring
  Bit error of transmission data can be detected. Performance monitoring supervises B1 Code Violation for SONET/SDH and 10B/8B Code Violation for GbE.
-Pass-through module
  Economical and unique solution for very short-distance transmission. Data signal can be dropped at relay station between terminal stations by using this module.
1. Low running costs & reduced hidden costs
Compact chassis (1U/1.5U/2U) enables reduction of Collocation Cost
In comparison with DWDM, CWDM technology saves heavily on maintenance costs
2. Flexibility
Multi Protocol & Protocol independent
Multi-rate simultaneous (10GbE,GbE,OC-n and Fibre Channel)
Long Reach : APD (Avalanche Photodiode) can support large loss budget
3. Easy installation & easy to handle
Electrical Back Plane & Hot/Swapable module
Optical Patch Code inside the chassis
4. Management
Out-band & In-line managemen
Save the configuration file to external server by FTP
