We describe a 5km-10Gb/s transmission at 850nm using a single-mode photonic crystal fiber (PCF), a vertical cavity surface emitting laser (VCSEL), and a Si-avalanche photodiode (APD).The fabricated PCF has an endlessly single-mode property. The transmission loss and dispersion of the fabricated PCF were 5.2dB/km and -62.8ps/nm/km, respectively. We also fabricate erbium-doped fluoride fiber amplifier (EDFFA), which operates at 850nm and report the gain characteristics of EDFFA. 10Gb/s NRZ signals were successfully transmitted over 5km.
