What applications are best suited for the PL7CU30T / PL7CU30R4 system?
This C-Band link is designed for professional satellite uplink operations, teleport facilities, and other RF environments that require stable, long-distance transmission over fiber with minimal signal degradation.
How does the C-Band performance differ from the L-Band models?
The PL7CU30T / PL7CU30R4 operates in the higher 5800 to 6800 MHz range, offering greater bandwidth efficiency and improved resistance to rain fade and interference compared to lower-frequency L-Band systems.
What type of control interface is available for operators?
Operators can manage the system locally via the front-panel LCD or remotely over SNMP, including monitoring of optical power, RF performance, alarms, and calibration data.
Can the system integrate with existing fiber networks?
Yes. The units support 1550 nm and CWDM ITU-Grid laser options, enabling compatibility with existing fiber infrastructures and allowing multi-channel transmission over a single fiber when required.
What maintenance considerations are required for long-term operation?
The transmitter and receiver modules are hot-swappable, each with an independent processor for diagnostic monitoring. The fan-free chassis minimizes moving parts, reducing maintenance needs and increasing long-term reliability.
