TERMINAL LOOP AND DROP USING TRAIL TRACE IDENTIFIER (TTI) OVERHEAD FOR A DENSE WAVELENGTH-DIVISION MULTIPLEXING (DWDM) COHERENT INTERFACE

The current hardware design of Dense Wavelength-Division Multiplexing (DWDM) coherent receivers involves a Drop and Continue design for line loopback operations, which causes the transmit side of a DWDM coherent transmitter to continue to push out Layer ...

1 Mbps coherent one-way QKD with dense wavelength division multiplexing and hardware key distillation [PDF]

We present the latest results obtained with a quantum cryptography prototype based on a coherent-one way quantum key distribution (QKD) scheme. To support its continuous high rate secret key generation we developed different low-noise single photon ...

Fault Tolerant Dense Wavelength Division Multiplexing Optical Transport Networks, Journal of Telecommunications and Information Technology, 2009, nr 1

, 2009
Design of fault tolerant dense wavelength division multiplexing (DWDM) backbones is a major issue for service provision in the presence of failures. The problem is an NP-hard problem.
