3G-SDI / HD-SDI Fiber Optic Extender Kit – Uncompressed Video & Audio up to 20km

Reliable Long-Distance 3G/HD-SDI Video Transmission Over Fiber

The MEFIBEROPTIC 3G-SDI/HD-SDI Fiber Optic Extender Kit provides a robust and cost-effective solution for transmitting high-definition video signals over extended distances using fiber optic cable. Ideal for broadcast, professional AV, surveillance, and live event productions, this kit extends uncompressed SDI signals with embedded audio up to 20km (12.4 miles) over a single singlemode fiber, far exceeding the limitations of traditional coaxial cabling.

This extender system consists of a Transmitter (Tx) unit and a Receiver (Rx) unit. The transmitter converts the incoming SDI signal into an optical signal, while the receiver converts it back to an electrical SDI signal at the remote end. Supporting data rates up to 2.97 Gbps, it handles SD-SDI (270 Mbps), HD-SDI (1.485 Gbps), and 3G-SDI (2.97 Gbps) signals, ensuring compatibility with a wide range of professional video equipment and resolutions up to 1080p@60Hz.

The integrated SDI loop-out port on the transmitter allows for simultaneous local monitoring, while features like automatic cable equalization ensure optimal signal quality. Fiber optic transmission offers inherent immunity to electromagnetic interference (EMI) and radio frequency interference (RFI), making it perfect for noisy environments.

Frequently Asked Questions (FAQ) for HD-SDI Fiber Optic Extender:

• Q1: What is the maximum resolution supported by this extender?
  • A1: This extender supports resolutions up to 1080p@60Hz for 3G-SDI signals, as well as 1080i and 720p for HD-SDI, and standard definition for SD-SDI.
• Q2: Does this extender transmit audio as well?
  • A2: Yes, it transmits embedded audio along with the video signal, supporting up to 16 channels as per SDI standards.
• Q3: What type of fiber optic cable do I need?
  • A3: This model is designed for use with singlemode fiber optic cable (typically 9/125µm9/125\text{µm}9/125µm) with [SC/LC/FC] connectors. (Specify connector type). Using multimode fiber will result in very limited transmission distance and poor performance.
• Q4: What is an SDI loop-out?
  • A4: The SDI loop-out port on the transmitter allows you to connect a local monitor or other SDI equipment to view the source signal before it’s converted and sent over the fiber. This is useful for monitoring and troubleshooting.
• Q5: Is this a single-fiber or dual-fiber solution?
  • A5: (State clearly based on product specs) Example: “This model uses WDM (Wavelength Division Multiplexing) technology and requires only a single strand of singlemode fiber.” OR “This model requires two strands of singlemode fiber, one for transmit and one for receive.”
• Q6: Can I use this for distances shorter than 20km?
  • A6: Yes, the extender will work perfectly fine for distances shorter than its maximum rated distance of 20km. Optical attenuators are generally not needed unless the optical power is excessively high at very short distances, which is rare for these types of extenders.
• Q7: Does it support camera control signals like PTZ?
  • A7: (Answer based on product features) Example: “This model also supports bidirectional RS485 data transmission, which can be used for PTZ camera control.” OR “This model focuses on video and audio transmission only and does not include a separate data channel.”

Quick Setup Guide:

1. Connect Video Source: Connect your SDI video source (e.g., camera, recorder output) to the “SDI IN” BNC port on the Transmitter (Tx) unit using a high-quality 75Ω SDI coaxial cable.
2. Local Monitoring (Optional): If desired, connect a local SDI monitor to the “SDI LOOP OUT” BNC port on the Tx unit.
3. Connect Fiber Optic Cable: Connect one end of a singlemode fiber optic cable (with [SC/LC/FC] connectors) to the fiber optic port on the Tx unit. Connect the other end of the fiber cable to the fiber optic port on the Receiver (Rx) unit. Ensure connectors are clean and properly seated.
4. Connect Video Display: Connect your remote SDI display (e.g., monitor, recorder input) to the “SDI OUT” BNC port on the Rx unit using a 75Ω SDI coaxial cable.
5. Power On: Connect the included power adapters to both the Tx and Rx units and plug them into power outlets.
6. Verify Operation: Check for power and signal status LEDs on both units. You should see the video signal from your source appearing on the remote display.
7. (If Applicable) Connect Data: If your model supports data transmission (e.g., RS485), connect your data lines to the appropriate terminal blocks on both the Tx and Rx units, ensuring correct polarity.
