  • Page 6 OSFP Test Adapter User Manual Included with the OSFP-TPAxxx-MCB-R is a spare Molex receptacle connector, provided for users to interface with the Low-Speed connection on the MCB. The Molex part numbers for the included receptacle, and contact pins are as follows.
  • Page 7 The Cooling Module Accessory (Included with product or optional accessory) can be installed to the OSFP MCB (Receptacle) Test Adapter. This will increase airflow through a device module (DUT) connector’s heat sink and subsequently keep the device module case temperature within recommended ranges (per OSFP MSA).
  • Page 8 70°C, as defined by OSFP MSA Standards . Thermal measurements at an ambient temperature of 20°C were taken of two typical OSFP Module types used with the OSFP MCB TPA while the Cooling Module was powered on. Temperature results for each power class as well as usage recommendations are shown below.

  • Page 10 32.29 10.0 At a power consumption greater than 27 Watts, the Closed Top Heat Sink OSFP module exceeds the recommended case temperature of 70°C. In these cases, the test operator must use caution when handling the OSFP module. Refer to the ‘Fan Module Usage Recommendations and Thermal Safety Precautions’...
  • Page 11 While testing an OSFP device module with the OSFP MCB TPA, the test operator should adhere to the following usage recommendations and thermal safety precautions. • The Cooling Module should always be on while the DUT is inserted in the OSFP MCB TPA. • The user must manually turn on the Cooling Module.
  • Page 12 Retain the outer cardboard shipping container until the contents of the shipment have been inspected for completeness and the product has been checked mechanically and electrically. Use the foam-lined instrument-case for secure storage of the Wilder Technologies OSFP Test Adapter when not in use.
  • Page 13 If the OSFP TPA must be turned or twisted to make connection to the DUT, avoid using the OSFP TPA housing alone to make this occur. Try to distribute the torque forces along the length of the test setup and cabling.
  • Page 14 • CAUTION 7: ESD Sensitivity The OSFP HCB is predominantly a passive component and is not in itself sensitive to electrostatic discharge (ESD). The OSFP MCB has active components and is sensitive to ESD. When an active DUT is installed, both devices become susceptible to ESD. Observe proper ESD precautions, discussed further in the Electrostatic Discharge Information section.
  • Page 15 Before each use of the OSFP TPA, ensure that all connectors are clean. Handle all cables carefully and store the OSFP TPA in the foam-lined instrument case when not in use, if possible. Do not set connectors contact end down. Install the coax connector protective end caps when the OSFP TPA is not in use.
  • Page 16 Electrostatic Discharge Information Protection against electrostatic discharge (ESD) is essential while connecting, inspecting, or cleaning the OSFP TPA test adapter and connectors attached to a static-sensitive circuit (such as those found in test sets). Electrostatic discharge can damage or destroy electronic components. Be sure to perform all work on electronic assemblies at a static-safe workstation, using two types of ESD protection: •...
  • Page 17 The MCB receives input signals from a signal generator connected to its TX lines (indicated by TX IN). These signals are then transferred to the OSFP module under test (indicated by TX OUT). The module responds with the RX IN signal, which is transferred through the MCB, and outputted to a connected oscilloscope through its RX lines.
  • Page 18 Figure 9. Closeup of OSFP I/O’s and External Functions The Module Source Switch allows a user to select which power input supplies the 3.3V OSFP connector pins. With the switch in the EXT PWR position the module will take power from the External 3.3V Power connectors (banana jacks).
  • Page 19 Two Wire Interface. To access this information, use the Wilder Technologies CMIS GUI software. Installation and instructions are in the CMIS GUI user manual (910-0070-000). This manual is provided on USB Flash Drive supplied with the OSFP MCB product.
  • Page 20 An RX signal, inputted from a connected Signal Generator, is transferred through the HCB’s RX lines into the OSFP host under test. The Host responds by outputting TX signals which are transferred through the HCB, out through its TX lines into a connected Oscilloscope for measurement.
  • Page 21 Channel De-Embedding The OSFP TX and RX channels are fully passive. Therefore, calibration compensating for the losses must occur within the test instrumentation that drives the OSFP Receivers or looks at the response of the OSFP Transmitters. The OSFP TPA’s have Touchstone S4P files for de-embedding the electrical length and losses within the TPA up to the OSFP connector interface pads.
