Product Overview +

Essential Optical Signal Management

The Evertz 7705 WDM and Optical Splitter Series (7705WDM, 7705WDM13/15, 7705DS, and 7705MS) delivers passive optical routing, wavelength combining, and signal splitting within a compact card-based form factor. Engineered for single-mode fiber networks, these single-slot modules allow broadcast engineers and telecommunications operators to optimize fiber utilization, create redundant signal paths, and integrate non-intrusive signal monitoring into live video transport environments.

Specialized Multiplexing and Precision Splitting Options

The series is tailored to specific optical workflow needs across four functional variants:

  • 7705WDM & 7705WDM13/15: Multiplex and demultiplex 1310nm and 1550nm/CWDM waveband signals over a single fiber strand, doubling transport capacity across legacy links.
  • 7705DS (Dual Splitter): Evenly divides an incoming optical signal into two 50% power outputs, ideal for feeding primary and backup transmission lines simultaneously.
  • 7705MS (Monitoring Splitter): Directs 80% of optical power to the main signal path while diverting 20% to a dedicated test port for real-time monitoring without interrupting main operations.

Streamlined Uptime and Frame Integration

Designed to meet strict broadcast uptime standards, the 7705 WDM and Splitter series features a front-of-frame hot-swappable design. Technicians can perform maintenance or swap modules without disturbing rear fiber connections, guaranteeing that adjacent active channels remain fully operational. Occupying a single slot across Evertz 7801FR, 7800FR, and 350FR frame enclosures, these passive modules provide a reliable foundation for Studio-to-Transmitter Links (STL), venue distribution, and facility expansions.
