Hirundo DFB laser modules are designed for forward-pathCATV applications, especially digital transmission using Quadrature Amplitude Modulation (QAM).The modules are designed to
incorporate high output power while maintaining high linearity.The devices feature standard pin assignments(compatible with OC-48).These devices offer excellent performance in directly-modulation QAM transmission,offering considerable cost savings over externally-modulated solutions. The combination of high performance and very reasonable price make these modules the most cost-effective CATV transmitter solutions in the industry.
