| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We have recently proposed a simple digital coherent transmission system with an injection locking technique for a next generation (5G and post 5G) high-capacity mobile fronthaul. With this scheme, we have demonstrated an 80 Gbit/s, 256 QAM 26 km bidirectional transmission. In this paper, we increase the symbol rate of our previous coherent mobile fronthaul transmission to 10 Gsymbol/s and demonstrate a 160 Gbit/s, 256 QAM bidirectional injection-locked coherent transmission over 26 km-SMF. Here, we evaluate the influence of backward Rayleigh scattering in uplink and downlink data signals. Furthermore, we investigate the loss budget in detail. | |
