Transmitter Output Eye5

Typically compliant with OC-3/STM-1 eye mask (GR-253-CORE

and G. 957) without filter, but not guaranteed and not tested for.

1Data rate ranges from 50Mb/s to 266Mb/s. However, some degradation may be incurred in overall performance.

2Measured average power coupled into 62.5/125µm, 0.275 NA graded-index multimode fiber. The minimum power specified is at Beginning-of-Life.

3The Center Wavelength, Spectral Width and Optical Rise/Fall Time satisfy the trade-off curves in FDDI PMD document as shown in Figure 1.

4Defined as 12.6 times the rms value per FDDI PMD.

5Compliance with the Optical Pulse Envelope in FDDI PMD is not specified and is not claimed.
