1.Product Description
PN：WLS-XXXXX2114-01
The WLS-XXXXX2114-01 DFB laser modules are designed for forward-path CATV 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.
Applications:
l1550-nm broadcast and point-to-point applications
lDigital CATV transmission
lSensing
lTesting system
Features:
lMeets GR 468 reliability specifications
