IEC 62300:2004 PDF

Overview

IEC 62300:2004 defines a standardized digital interface for consumer audio/video equipment that uses plastic optical fibre (POF). It specifies the principal electrical and optical parameters for a POF-based consumer AV digital link - including transmitter/receiver requirements, link budget, physical fibre and connector characteristics, and basic safety checks. (This entry corresponds to the IEC monolingual English edition published in 2004; a bilingual version exists.)

Key topics and technical requirements

• Maximum bit rate: up to 500 Mbit/s for wide‑band POF links.
• Link length: single‑hop distances from 1 m to 50 m.
• Electrical interface: differential signaling, PECL levels, nominal amplitude 800 mV ±250 mV.
• Optical transmitter: center wavelength ≈650 nm ±10 nm, mean launched power –6 to –2 dBm, RMS spectral width ≤20 nm, extinction ratio ≥10 dB.
• Receiver: specified overload and sensitivity levels (document lists overload at –2 dBm and sensitivity at –19 dBm, at the stated BER).
• Signal quality: transmitter/receiver eye‑mask and maximum rise/fall time 1 ns (10–90%) are defined to ensure reliable digital transmission.
• Wide‑band POF physical specs (Annex A): cladding diameter 750 µm, jacket 2.2 mm, transmission loss **
