Brand Name : Yatai

Product description

YOC-1550 is a kind of external modulation optical transmitter working at the 1550nm wavelength; it can transmit not only simulated signal but also digital signal used in CATV. The radio-frequency input signals drive the lithium niobate modulator (LINBO3) to modulate the 1500nm laser, and the chirp effect can be eliminated by this structure. The optical transmitter is powered by alternating current. Size: W485mm×D490mm×H45mm Weight: 5kg. Features 1. High power balanced output (2 ports) 2. Compatible with frequency properties (NTSC, CENELEC and PAL) 3. Low noise figure,high rate of carrier to noise 4. High CSO, CTB, XMOD performance 5. Predistortion AGC radio frequency circuit with digital adjustable gain (0.5db every step) 6. High performance Soc with 12BitD/A, with precise digital laser temperature control and power control 7. Totally-enclosed chassis with left and right air channel, fitting for various terrible environments 8. States and parameters display on the front panel 9. Change of states and parameters can be monitored by RJ-45 interface 10. Software upgrade and system monitor with RS-232 interface 11. Remote network management by SNMP protocol through the RJ-45 interface.   Optical parameter
