Video and control data travel down a single-mode optical fiber instead of an RF link, so the connection is immune to electromagnetic interference and jamming, cannot be intercepted over the air, and does not depend on line of sight. The fiber pays off a purpose-built drum that carries the sky-end module inside it, and terminates at a ground-end module that hands off video and serial data. Specifications Fiber and pay-off reel Fiber length: 5,100 m, nominal 5 km Fiber type: single-mode, 9/125 micron. The factory QC label on this actual reel reads G657A2 bend-insensitive fiber, link tested at 1550 nm, 0.3 dB/km or better , insertion loss 0.3 dB or better, appearance inspection PASS. Optical cable diameter: 0.26 mm Reel: 94 mm diameter x 445 mm, ABS shell, aluminium-alloy outlet nozzle Reel weight: 0.60 kg including the sky-end module Ground-end module, Opticallink GBD-MAX Product name: fiber optic image and data ground module Shell: aluminium alloy, 123 x 56 x 31 mm, 186 g Optical interface: FC connector - not SC and not LC Fiber mode: single mode, single fiber Wavelengths: 1310 nm (9/125 micron) and 1550 nm Data interface: GH1.25 serial | BNC video interface Video formats: NTSC / PAL / SECAM Data direction: bidirectional | Data format: TTL / S.BUS Data speed: 0 - 1 Mbps Manufacturer's stated transmission distance for the module over single-mode fiber: 0 - 60 km External power: XT60, 3-6S Important - Battery Not Included The ground-end module has a battery tank that takes a Sony NP-F style pack ( NP-F960 / F970 / F980 / F990T ). The manufacturer does not include that battery, and no battery is included here either. Budget for one, or power the module from its XT60 input. Photos Photos 2 and 3 are of the actual item.
