FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

How far can a broadcast camera be powered over SMPTE 311M hybrid cable?
Using the four 20 AWG power conductors connected in parallel pairs (2 × ~1.04 mm² equivalent, loop resistance ~35.8 Ω/km) at 240 V AC from the Camera Control Unit (CCU), a standard HD/4K system camera with viewfinder and lens servo can operate at distances of 1,500 m to 2,500 m; optical video alone reaches over 10 km.
Why do we use ITU-T G.657.A2 bend-insensitive single-mode fibres instead of standard G.652.D?
During live sports and studio events, camera cables are frequently stepped on, knotted around tripod legs, or pulled tight around doorway corners. ITU-T G.657.A2 fibre maintains < 0.1 dB loss even at a 15 mm bend radius, preventing sudden 12G-SDI video blackouts.
Is this cable dimensionally matched to LEMO 3K.93C and Neutrik opticalCON connectors?
Yes. The central Ø 1.8 mm steel strength member, 0.9 mm tight buffers, 20/24 AWG insulation diameters and Ø 9.2 mm outer jacket are held to SMPTE ST 311 tolerances for LEMO 3K.93C, Canare F3A and Neutrik opticalCON crimping.
Can we order pre-terminated SMPTE 311M camera reel assemblies?
Yes. We supply bulk 300 m, 500 m and 1,000 m drums as well as pre-terminated LEMO 3K.93C or opticalCON camera reels from 25 m to 500 m.
