High modulated output power of +9.0 dBm transmitted over 80 km with L-band SOA assisted extended reach EADFB laser (AXEL)

We successfully transmitted a high modulated output power exceeding 9 dBm over 80 km of SMF by using an L-band extended reach EADFB laser (AXEL) without increasing of the power consumption and number of electrical input ports compared with an EADFB laser.
