Low Latency Optical Access (TIC-TOC: Time Controlled Tactile Optical Access)


Low Latency Optical Access (TIC-TOC: Time Controlled Tactile Optical Access)


Technology Summary


ETRI developed the 25Gb/s per wavelength optical access technology for 5G network, accommodating bandwidth-intensive as well as mission-critical low-latency services such as AR/VR, 4K UHD, drone and robot control, etc. 

The MAC/PHY prototype enables multiple wavelength operation with 25G Ethernet frame transmission with low latency access. 

A high sensitivity 10 Gb/s burstmode and a 25 Gb/s transceiver provide up & downstream transmission over 29 dB (PR30) of link budget.
