1550nm External Optical Transmitter Modulation CATV with Dual Power Supply
We believe that providing proven, efficient, simple and practical Splicer F Connector, High Quality Passive Optical Receiver, Passive Optical Node is the prerequisite for creating new value. Our high-quality service system and good reputation have been unanimously recognized by customers. We adhere to the development concept of scientific and technological innovation, and vigorously promote technological research and development and technological innovation. We are proud to be able to provide our valuable customers with competitive prices, timely delivery and good after-sales service support.
ST1550E Optic transmitter is usually used for long-distance transmission. By ITU-T wavelength, access to a broadband PON Network is easily implemented, or applying to the FTTH Solution by WDM Technologies.
Feature
◆Narrow bandwidth (Typ=1MHz), Lower noise, DFB continuous wave laser.
◆Unique innovation technology; Providing excellent CNR, CTB, CSO, SBS.
◆ITU standard wavelength is adjustable. Users can adjust and set the laser wavelength on the front-panel with ±0.05nm stepping in the range of ±200GHz (±1.6nm), while executing network upgrading and WDM System Expansion.
◆AGC/MGC Mode is optional at spot; OMI can be optimized at spot.
◆Perfect RS232 communications interface.
◆SNMP network management optional.
◆1+1 backup power supply optional.
◆Excellent P/P ratio.
