A “Development Platform” for prototyping new multi-GHz ATE has recently been introduced (Keezer et al. 2009). The first application was a multi-channel test system for characterizing an optical network switch operating at 2.5 Gbps
per channel (Keezer et al. 2009, 2010). Nine transmitter channels (TX) and nine receivers (RX) were used to test the Dense Wavelength Division Multiplexing (DWDM)
switching network. This present paper incorporates elements from the prototype designs into full-feature test modules targeting
applications between 2.5 Gbps and 24.0 Gbps per channel. Specifically, the optical test system is extended for burst-mode
12 Gbps DWDM packets (more than 4-times the rate of the original system). Using 8 TX channels, an aggregate data rate of 96 Gbps
is achieved. Alternatively, some modules can be configured to double the channel-count (up to 18) while operating at the lower
2.5 Gbps rate (45 Gbps aggregate rate). Lower rates permit use of lower-cost optical components. Two new modules are described
with testability features such as: (1) support for “loopback” testing of DUT output-to-inputs, (2) DC electrical tests, (3)
2-to-1 multiplexing up to 24 Gbps, (4) ATE self-test/calibration loopback paths. Recently multiple Development Platforms have
been constructed that can operate either independently or synchronized using very low-jitter (~1 ps RMS) clock distribution
paths. |
