Description
High-Fidelity Long-Distance Voice Transmission
The HL-2P Telephone Fiber Converter is a professional-grade communication solution engineered to provide high-fidelity, long-distance extension for two independent telephone lines over fiber optic cable. This system provides uncompressed digital transmission with zero delay, ensuring crystal-clear speech and total signal stability without crosstalk or degradation. It seamlessly supports standard public switched telephone network (PSTN) lines, private branch exchange (PBX) extensions, fax machines, Caller ID pass-through, and polarity reversal signals for specialized billing functions.
Advanced Electrical Isolation and Surge Protection
Designed to safely operate in highly demanding electrical environments, the HL-2P Telephone Fiber Converter features top-tier hardware protection. The internal telephone interfaces are fully isolated from other circuitry using high-quality audio transformers and photoelectric couplers, effectively preventing ground loops and protecting connected PBX exchange equipment. Additionally, every RJ11 voice channel incorporates robust three-level over-current and over-voltage protection to deliver superior lightning and electrical surge resistance.
Flexible Optical Network Deployment
The HL-2P Telephone Fiber Converter offers highly adaptable optical options, supporting either single-fiber or dual-fiber configurations depending on project needs. It spans a standard distance of 1 KM over multi-mode fiber networks and 20 KM over single-mode fiber, with customizable configurations that can scale up to 100 KM for long-haul installations. This standardized hardware is purely plug-and-play, eliminating the need for manual gain adjustments, software setups, or debugging, and features integrated diagnostic LEDs for instantaneous troubleshooting of line activity and link status.
