Video extender AJA FiDO-T single-channel SDI to fiber 1310nm with looping output

AJA FiDO-T single-channel SDI to fiber 1310nm with looping output converts a single SDI video signal to single-mode fiber transmission at 1310 nm while providing a loop-through SDI output for local monitoring or daisy-chaining. The unit is designed for professional broadcast, live event and studio installations that require reliable long-distance SDI transport with minimal signal degradation. It supports standard SDI formats and offers straightforward connectivity to integrate with existing SDI and fiber infrastructures.

Advantages

The device provides stable SDI-to-fiber conversion over single-mode cable at 1310 nm, enabling long-range transmission without repeated electrical reclocking points. The integrated SDI loop output preserves a native SDI feed for nearby monitoring or chaining multiple devices. Its compact, rackable form factor and fixed-function design reduce setup complexity and maintenance. The converter is engineered for consistent signal integrity and low-latency operation, making it suitable for time-sensitive production workflows.

Suitable for

• Broadcast transmission links between control rooms and transmitter sites
• Live event and concert venue signal distribution over long distances
• Studio interconnects where fiber runs replace long coaxial cable
• Daisy-chaining multiple SDI endpoints with a local loop output for monitoring

Key specifications

• Input: single-channel SDI (BNC)
• Output: single-mode fiber 1310 nm
• Looping output: SDI loop-through (BNC)
• Supported formats: standard SD/HD/3G-SDI formats (per manufacturer specification)
• Latency: low, suitable for live production
• Form factor: compact, rack-compatible enclosure

How to use

Connect the source SDI output to the FiDO-T SDI input using a standard BNC cable. Attach a single-mode fiber cable to the fiber output port for long-distance transmission and connect the local SDI loop output to a monitor or downstream SDI device if local monitoring or daisy-chaining is required. Ensure correct fiber connectors and polarity when making fiber connections and secure all BNC and fiber connections to prevent signal interruptions. Power the unit using the supplied power adapter or compatible rack power solution and verify signal presence at the remote receiver or monitoring point.

Usage recommendations

Use single-mode fiber rated for 1310 nm transmission and test fiber links with appropriate optical test equipment to confirm loss and polarity. Keep BNC cable lengths short for local monitoring to preserve signal quality, and avoid unnecessary adapter chains. For mission-critical deployments, plan redundant fiber paths or use complementary redundant power arrangements to increase reliability.
