Cost-effective hybrid Fast-Ethernet switch for POF networks
Abstract: In previous works, we introduced plastic optical fibers (POF) as a competitive transmission media for industrial, office and home networks. In fact, we proposed that nowadays a good solution
50G PAM4 Technical White Paper
The Ethernet technology has been using the NRZ modulation code ever since it appeared in 1980s. Only 100BASE-T interfaces use the multi-order modulation code. After developing to 100GE, the
Cost-effective hybrid Fast-Ethernet switch for POF networks
Conclusions: We have designed a hybrid electro-optical switch for Fast Ethernet to use with standard 1mm SI-POF based networks, and implemented a sample of six units.
