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.
