DS3 Fiber Modem | T3 Fiber Modem

Description

Description

The DS3 Fiber Modem is used to provide 44.736M (T3) converter between electrical interface and optical interface of PDH network.

The converter features compactness, light weight, low power consumption and high reliability.

The 45M O/E Converter operates on 1.31mm lasers, with a typical transmission distance of 40 km over single mode optical fibers. For longer hops, 1.55mm laser sources may be selected.

Exterior power supply, all the functional blocks are integrated on a single PC board, which makes the converter compact and reliable. 220 V AC or – 48 V DC power options are available by selecting an appropriate plug-in power unit.

This industrial-grade modem converts DS3 (44.736 Mbps) or T3 (45 Mbps) electrical signals to optical fiber for long-distance, high-bandwidth transmission. Ideal for telecommunications carriers, ISPs, and enterprises needing to:

• Extend Network Reach: Overcome copper distance limitations (up to 100km with fiber).

• Ensure Signal Integrity: Fiber eliminates EMI/RFI interference and voltage surges.

• Simplify Infrastructure: Replace coaxial cables with lightweight, high-capacity fiber.

  • Bidirectional DS3/T3-to-fiber conversion.

  • Supports single-mode fiber (long-haul) or multi-mode fiber (short-range).

  • Low latency, error-free transmission with advanced clock recovery.

  • 19-inch rack-mount design for easy deployment.

  • Diagnostic LEDs for real-time monitoring.
