Specifications
N
The FOX HD-SDI is a transceiver that can function as a
transmitter and/or as a receiver. Two units are required for a
transmitter-receiver system with one fiber optic cable linking
the two units. The FOX HD-SDI is available in single mode or
multimode versions.
N
These transceivers are class 1 laser products. They meet the
safety regulations of IEC-60825, FDA 21, CFR 1040.10, and
FDA 21 CFR 1040.11.

N
Operating distance is approximate. These are typical
distances. The maximum distance may be greater than these
typical numbers depending on factors such as fiber type, fiber
bandwidth, connector splicing, losses, modal or chromatic
dispersion, environmental factors, and kinks.
