SFP+ provides hand in reducing the overall system cost. On the other, its physical layer (PHY) and performance are put with brand-new burdens. The SERDES framer interface (SFI) between the host board and the  SFP+ module  displays great design and testing challenges. One challenge attributes to the increased port density and the testing time required for 48 or more ports per rack. For example, there are 15 measurements each for the host transmitter tests, and each of these measurements using manual methods can certainly take from three to five minutes. This means it will take engineers more than an hour per port to complete the required tests. The second one that engineers have to consider is: if a measurement fails, how can they determine which component is causing such a failure, and how they debug the issue to arrive at the root cause. Such determinations are especially challenging because of the tight physical packaging and compact designs. Another challenge falls on...

TWDPc, short for transmitter waveform distortion penalty for copper, takes a special algorithm defined by the SFP+ specification. This test is normally thought as a way of measuring the deterministic dispersion penalty because of a specific transmitter with regards to the emulated multimode fiber and a well- characterized receiver. The TWDPc script (of 802.3aq,  Juniper 10GBASE-LRM  ) processes a PRBS9 pattern requiring at least 16 samples per unit interval. Out of concern for the large installed base of equivalent-time oscilloscopes with an archive amount of around 4000 samples, the requirement for 16 samples per unit interval was relaxed to seven samples per unit interval. The relaxation of the necessity from 16 samples per unit interval to simply seven samples per unit interval causes worst-case pessimism of 0.24 dB TWDPc over 30 measurements. For DUTs that curently have a higher TWDPc, 0.24 dB could possibly be the difference between a pass or a fail result. The TWDP...

IEEE 802.3ba defines the rate of 100GE as 103.125Gbit/s. OIF defines two types of CFP: 4 wavelengths (4×25G, 100GBASE-LR4/ER4) and 10 wavelengths (10×10G, 100GBASE-SR10/LR10). 2. Line side optical transceiver DWDM long-distance transmission is principally limited by physical limitations such as OSNR, dispersion, non-linear effects, PMD and so forth. The allowable dispersion tolerance of the system decreases in proportion to the square of the rate; the DGD tolerance is inversely proportional to the rate. The higher the rate, the smaller the DGD allowed by the system, and the statistical characteristics of the signal polarization change make the P...
