YOC-1550 1550nm 1U High Performance Optical Transmitter Cable TV Directly Adjustable Optical Transmitter

YOC-1550 1550nm 1U High Performance Optical Transmitter Cable TV Directly Adjustable Optical Transmitter

Description:
- The YOC-1550/10 series optical transmitter products belong to a new type of high-performance optical transmitter. The transmitter is at a height of 1U, Can be easily installed on the 19” rack. The main components use for AOI, for XT, for JDUS, for Fujitsu, for MITSUBISHI DFB low noise, continuous wave lasers with thermoelectric coolers. Due to the use of international brands and our company's system optimization control technology, SMNP network control technology, the technical performance indicators of the entire machine fully meet the standards of similar imported equipment, providing high-quality image, digital or compressed digital signal long-distance transmission for cable television and telephone communication Lose.

Features:
- High quality: The original system optimization control technology and RF pre-distortion technology ensure the maximum CTB, CSO, and SBS indicators of the system while ensuring excellent performance of CNR.
- Flexibility: The laser emission and RF processing circuits adopt a modular design approach, greatly facilitating the after-sales service of products and the import customs clearance procedures for foreign merchants.
- Reliability: Adopting a 19” 1U standard rack, equipped with a high-performance dual switch power supply, capable of hot backup operation at a voltage of 85-265VAC in the city network, and MS level fully automatic switching; The heat dissipation of the chassis can be automatically controlled by temperature.
- Intuitiveness: The built-in microprocessor of the machine monitors the working state of the pump laser. At the same time, the panel LCD can display the working parameters.
- Network management type: The optional status monitoring transponder is compatible with the SCTE HMS standard, which can realize network management monitoring.
- Power plug-in type: The plug-in type switching power supply adopts aluminum profile structure, which is conducive to heat dissipation and replacement. And dual power hot and cold backup.

Precaution:
- Before connecting, carefully clean all fiber optic joints and connectors;
- Remove the dust cap of the optical fiber connector and ensure that the optical connector is the APC end surface;
- The key to cleaning fiber optic connectors is to use a dry, lint free special wiping cloth; In addition, it is best to use a dedicated microscope (at 100X and 200X respectively) to check the cleanliness or defects of the end surface of the fiber optic connector;
- Pay attention to keeping the fiber optic connectors clean and tidy;
- Clean the fiber optic connectors (flanges)
- Special compressed gas can be used to clean the surface of fiber optic connectors;
- It can remove dust smaller than 0.2 microns, with better results and no residue;
- Hold the compressed air tank about 6 inches away from the connector, align it with the flange, and briefly press the nozzle switch several times to complete the cleaning of the connector;
- If there is no dedicated compressed air, a 2.5mm cleaning cotton swab can also be used as a substitute to clean the fiber optic transmission connector, or the installation flange can be removed and the fiber optic jumper connector on the other side can be cleaned directly;
- Attention: Be very careful when handling fiber optic connectors to avoid damage.
- Connect the output of the optical transmitter to the optical power meter with the optical fiber jumper;
- Turn the laser key switch on the front panel of the transmitter to the "ON" position;
- Use a Optical power meter to check whether the output optical power of the transmitter is within the normal range;
- This machine should have good grounding, and the grounding resistance should be less than 4ohm. According to international standards, the 220Vac incoming line adopts a three wire system, and the neutral line is the grounding wire.
- This machine should be installed in a heat, cold, and moisture resistant environment to avoid excessive temperature and humidity affecting the service life of the entire machine.
- This machine adopts a high-performance and highly reliable switching power supply with constant voltage overcurrent protection. The switching power supply is internally equipped with a 2A imported fuse, which can work on the 85Vac to 265Vac power grid. This machine uses dual power supplies, one of which can be used for cold and hot backup. It is recommended to use hot backup.

Package Included:
- 1 x Optical Transmitter
