1550 Fiber Transmitter
1550 nm Direct Diode Modulation
4C1500AC (40~1GHz) 4C1500A 40~870 MHz)
1550nm Direct Diode Modulation CATV Optic Transmitter
Product Description
Direct modulation will lead to
high laser chirp (Laser's bias current is modulated by
signal and the optical spectrum FM's). Laser chip will
interact with dispersion effect caused by standard
single mode fiber (SMF-28), which will generate serious
CSO distortion . This distortion will become more
serious with the increase of transmission distance,
bandwidth and channel number.
Today we can maintain acceptable
signal quality while transmitting an analog and digital
full channel signal with transmission distance≤15Km or
transmitting digital load with transmission
distance≤40Km.
