Transmitter Optical Signal Characteristics
Notes:
1. Average value when transmitting modulated light at signal timing parameters. The output power coupled into plastic fiber P
2. MOST
3. Center wavelength and spectral bandwidth RMS are defined as:
4. Using a Jitter Filter specified in
5. Using a Golden PLL specified in
6. Maximum allowed total jitter is derived from eye definition specified in
7. Parameters are normalized and calculated relatively to the measured b
8. Typical jitter value is measured with MOST
Transmitter Timing Characteristics
Eye Safety
The transmitter device emits light with a wavelength of 650 nm (red). This product is designed to avoid damage to the
unprotected eye. To indicate the classification of the light source, a label as depicted in the subsequent figure can be
used. However these labels are not mandatory on the product according to IEC 60825 version 1.2 paragraph 1.1.
