We propose and experimentally demonstrate mutual optical format conversion between signals characterized as 10-Gb/s nonreturn-to-zero on-off-keying (NRZ-OOK) and NRZ binary phase-shift keying (BPSK) *** conversion is based on stimulated Brillouin scattering (SBS) in a single-mode optical *** OOK signal is converted into a BPSK signal through optical carrier absorption,for which a SBS loss of 30 MHz is used in long-haul *** converted BPSK signal is reverted to an OOK signal with a corresponding SBS gain of 30 MHz for direct *** proposed OOK-to-BPSK and BPSK-to-OOK format conversions can be implemented in transmitter and receiver nodes by using a laser source as the Brillouin pump.
BitTorrent(BT) has emerged as one of the most popular protocols for content sharing in recent years. Most BT applications are network-oblivious which brings great challenges to traffic engineering. As basic input info...
