Huatai 1550nm satellite TV external modulated optical transmitter HES-26S, adopts external modulated technology, no laser chirp, very low dispersion distortion, high extinction ratio. It applies to long distance, high quality network application. It can transmit 950~2600MHz satellite SAT-IF signal through one fiber.
HES-26S can be compatible with any FTTx PON technology, and applies to DWDM system application, ITU-T standard tunable wavelength optional.
HES-26S adopts low noise, narrow band, continuous wave laser as optical source, it adopts high bandwidth LiNbo3 external modulator as signal to eliminate 1550 nmlaser to control the chirp. Excellent laser APC, ATC control and external modulation bias control , perfect SNMP, RS232 interface, 1+1 power supply backup. High performance, high reliability and excellent performance price ratio. It is the best choice for subscribers.
