5.0 Gb/s 1550nm光發(fā)射機(jī) 單模輸出
The LT-1550 series is a high performance electrical to optical designed for applications requiring wide band digital modulation or high bit-rate data transmission. LT-1550 series transmitters utilize a narrow linewidth 1550nm wavelength DFB 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, TDM link, laboratory test and measurement.
LT-1550 series can be ordered with two versions of modulation bandwidth: 5Gb/s and 12.5Gb/s. Its DFB laser operating wavelength can also be custom ordered with any ITU DWDM grid within C-Band, at 100GHz channel spacing. The housing choice include a 19” rack mount and bench top model. All LT-1550 series products come with a standard 3 year limited warranty.
Features:
- Linewidth of DFB laser under 1MHz
- Broadband Lithium-Niobate modulator w/10GHz band width
- High gain RF driver module enable low input level
- Automatic Bias Control Circuit to ensure stable operation
- Excellent eye diagram for error-free transmission
- Connector choice: FC/APC, FC/UPC, SC/APC, SC/UPC, LC/APC, LC/UPC
- Polarization Maintaining (PM) output available (12.5Gb/s model)
- Available in rack mount or bench top housing
