Electro-optical parameters valid for each channel and measured at the highest specified data rate.

All optical parameters are measured with a 62.5 µm multimode fiber.

1)

20% - 80% level, non filtered values.

2)

The Total Jitter (TJ) is composed of Random Jitter (RJ) and Deterministic Jitter (DJ) according to:

TJ = RJ (14 Sigma value) + DJ.

The TJ is specified at a BER of 10

The RJ is measured at the 50% level of the optical signal as the mean of the rising and falling edge

measurement value.

3)

UI (Unit Interval) is equal to the length of one bit. For example, 2.72 Gbit/s corresponds to 368 ps.

4)

The DJ consists of Duty Cycle Distortion and Data Dependent Jitter and is measured according to IEEE 802.3

using a K28.5 pattern.

5)

With input channel-to-channel skew 0 ps and a maximum data channel-to-channel average deviation and

swing deviation of 5%.

6)

The specified output power is compliant with IEC 60825-1, Amendment 2, Class 1M Accessible Emission

Limits (AEL).

7)

Wavelength is measured according to IEEE 802.3, sec. 38.6.1.

8)

Spectral width is measured according to IEEE 802.3, sec. 38.6.1.

9)

RIN is measured according to IEEE 802.3, sec. 38.6.4.

10)

Peak to peak values.

11)

OMA is defined as the difference of the optical high state (’1’) and the optical low state (’0’):

OMA = P

12)

Corresponds to a minimum extinction ratio of 6 dB.

13)

Corresponds to a typical extinction ratio of 8 dB.
