12.5Gb/s可調(diào)諧C波段光發(fā)射機 保偏輸出可用 機架式
The LT-TC series is a tunable wavelength electrical to optical designed for applications requiring dynamic wavelength allocation and high bit-rate transmission. LT-TC series transmitters utilize a widely tunable wavelength laser source and a broadband optical modulator to provide pure and efficient modulation. These products are ideal for DWDM or TDM digital data transmission up to 12.5Gb/s. It can also be a excellent product for electro-optic component characterization, DWDM networks, secure communication, laboratory test and measurement.
LT-TC series can be ordered with two versions of modulation bandwidth: 5Gb/s and 12.5Gb/s. Its operating wavelength can be tuned to any ITU DWDM grid within C-Band, at 25GHz channel spacing. The housing choice include a 19” rack mount and bench top model. All LT-TC series products come with a standard 3 year limited warranty.
