1. Product Overview
This SMPTE 311M broadcast camera composite breakout cable features one end terminated with LEMO 3K.93C (FUW) SMPTE hybrid connector, and the other end breakout with 2-core single-mode fiber terminated with ST/UPC fiber connectors. The cable integrates optical fibers and power copper conductors with heavy-duty outer jacket, offering tensile resistance, repeated flexing performance, dust & water resistance and anti-interference capability. It is designed to separate optical signals from SMPTE hybrid camera cables. It extracts fiber signals to connect to optical transceivers and fiber transmission equipment for long-distance transmission of HD/4K video, control and intercom signals. Note: This breakout version only brings out fiber channels; power copper conductors remain inside the LEMO connector side and are not terminated out.
Typical Applications: TV Studios, Gala Events, Sports Broadcasting, OB Vans, Field Video Production.

1.3 Cable Length (Customizable)

Standard options: 3m / 5m /10m
Custom length available upon customer request
Sample shown in picture: 2.5m

2. Optical Performance (G.652D SMF @1310nm /1550nm)

5. Electrical Specifications (Copper embedded in main cable, fiber-only breakout model)

The cable is integrated with power copper conductors to supply power for broadcast cameras. This breakout cable only extracts optical fiber signal channels, and power copper wires stay inside LEMO connector and are not breakout.

• Rated Voltage: AC 600V
• DC Resistance of conductors: Compliant with SMPTE311M
• Shielding: Full shielding structure to resist EMI/RFI interference, suitable for field environments with complex electromagnetic noise

6. Environmental Specifications

7. Reliability Test Items (Sampling Inspection before delivery)

1. Optical test: 100% Insertion Loss & Return Loss inspection
2. Mechanical test: Connector pull test, flex cycling test, torsion test
3. Environmental test: Temperature cycling, damp heat aging
4. Water proof test: IP65 spray test on connector

10. Ordering Code Rule

HZT-SMPTE-BO-ST02-[Length]
Example: HZT-SMPTE-BO-ST02-5M Meaning: SMPTE Breakout Cable, LEMO to ST dual fiber, 5 meters length

11. Important Notes

1. Do not touch fiber end face directly. Keep dust cap covered when unused, dust contamination will degrade optical performance.
2. Do not bend cable below minimum bend radius; avoid sharp objects cutting outer jacket.
3. Align locating notch and twist to lock when mating LEMO connector. Do NOT force plug/unplug.
4. This breakout cable only extracts fiber signals without power breakout. For version with power breakout, please refer to separate model.
