Reference Information

Specifications

NThe 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.

NThese 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.

Optical fiber interconnection between transmitter and receiver

Number/type 1 fiber optic

NOnly one fiber is required to transmit video and embedded audio and unidirectional data.

Connectors	1 LC connector
Operating distance	30 km (18.75 miles) with singlemode (SM)
	cables with a FOX HD‑SDI SM
	500 m (1640’) with multimode (MM)
	cables with a FOX HD‑SDI MM

NOperating 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.
