Product Overview
The 4E1 PDH optical transceiver is an optical transmission device developed and manufactured by our company using a proprietary, custom-designed integrated circuit. Centered around an ultra-large-scale integrated circuit, this equipment provides combined optical‑electrical transmission for up to 120 channels, supporting four E1 interfaces. It is suitable for small‑capacity exchange‑based network deployments, subscriber loop networks, mobile communications (base stations), private networks, DDN networks, and more.
The 4E1 PDH optical transceiver also features a centralized chassis design for easy maintenance, plug-and-play operation, and comprehensive network management capabilities.
Product Features
1. Provides four E1 digital interfaces.
2. It employs large-scale integrated circuits, featuring a simple circuit design, low power consumption, and high reliability.
3. Compatible with multiple power supply environments—48 VDC or 220 VAC.
4. Standard 1U rack-mount design, ensuring stable and reliable operation with easy installation.
5. Enhanced status display functionality for easier maintenance and management.
