Arista SFP-10G-T Latch Requirements

The SFP transceiver latch should be mechanically robust and designed to prevent unintentional unlatching during insertion or extraction of the transceiver cable. The transceiver is designed with a “Bail type ejector latch mechanism” that allows the SFP module to be easily released from the cage, when the adjacent SFP ports in both rows are also populated and regardless of whether the SFP module is placed in the lower or upper row. The latch shall also pass the “wiggle” RJ45 connector stress test.

REGULATORY REQUIREMENTS

The SFP transceiver installed into the host system requires meeting compliance requirements listed in this paragraph. In order to achieve this, the module must be evaluated in considering its use in the equipment designs. Unless otherwise specified, the transceiver module shall meet the current version, at the time of manufacturing, of the applicable EMI/EMC specifications for telecommunication network and information technology/multimedia equipment.


RADIATED EMISSION (RE)

    1. KHz – 18.0 GHz is recommended frequency range for radiated emission testing. The 10G Base-T CuSFP transceiver shall meet the applicable FCC Part 15 emission requirements.

      10G Base-T CuSFP transceiver minimum emission requirements are:

      • Class B radiated emission requirements by using shielded cables at least 4dB margin.


        ELECTROSTATIC DISCHARGE (ESD)

        In addition, the CuSFP module or host platform shall not show susceptibility to conducted immunity when applied to the interface cable per the requirements of IEC 6100-4-2:

      • Contact ESD only to the accessible portions of the module (i.e. front panel connector receptacle). 8 kV - Air Discharge and 4 kV – Contact discharge.

      • Criteria B (see paragraph 6.7 for Criteria’s definition) should be used as a measurable effect from ESD applied (25 discharges by polarity – both air/contact) to the system used with CuSFP modules


TRAFFIC GENERATION AND SUSCEPTIBILITY CRITERIA

TRAFFIC GENERATION AND MONITORING.

A minimum 50% utilization will should be established for preliminary investigation when possible, with final evaluation being performed with a worst-case utilization.


SUSCEPTIBILITY CRITERIA

The disturbances will be applied to the system as a whole. Data losses will be reported according to the following performance criteria.


PERFORMANCE CRITERIA A

During the test and after the test, system with Cu SFP module shall continue to operate:


Monitoring Method

The Traffic Generator will be monitored. The link, speed, retry rates, etc. during the test will be reviewed by equipment status logs after the test, and monitored by LED observation during the test.


PERFORMANCE CRITERIA B

Error rate, request for retry and speed of data transmission rate may be degraded during the application of the test. Degradation of the performance as described in criteria A is permitted provided that the normal operation of the EUT is self- recoverable to the condition immediately before the application of the test. In these cases, operator response is not permitted to re-initiate an operation.


Monitoring Method

The Traffic Generator will be monitored. The link, speed, retry rates, etc. during the test will be reviewed by equipment status logs after the test, and monitored by LED observation during the test.


PERFORMANCE CRITERIA C

Degradation of the performance as described in criteria A is permitted provided that the normal operation of the EUT is self- recoverable to the condition immediately before the application of the test or can be restored after the test by the operator.


Monitoring Method:

The Traffic Generator will be monitored. The link, speed, retry rates, etc. during the test will be reviewed by equipment status logs after the test, and monitored by LED observation during the test.


FLAMMABILITY

The PCB of the SFP module shall be min. V-0 UL flame rated. Applicable standards: UL/CSA 60950 and IEC 60950.


ENVIRONMENTAL AND QUALITY REQUIREMENTS

ACCELERATED AGING

The SFP+ transceiver module shall be subjected to an accelerated aging test that exposes the module to 85C case temperature while being powered at 3.3V for 2000 hours.


Failure criteria

The product is considered to have failed this test if any of the following occurred:

  1. Failure of test unit to perform ping or traffic test.

  2. Excessive corrosion of components.


RELATIVE HUMIDITY (NON-OPERATIONAL)

The SFP+ transceiver module shall be subjected to the temperature and humidity profile as per MIL STD 202G Method 103B,


Test description

The module shall be subjected to the temperature and humidity profile of 85C/85% RH for 1000 hours. The product shall be non- operational during this entire period.


Failure criteria

The product is considered to have failed this test if any of the following occurred:

  1. Failure of test unit to perform ping or traffic test.

  2. Excessive corrosion of components.


    SHOCK AND VIBRATION


TEMPERATURE CYCLING

Thirty-Two Modules shall be place in a temperature cycling chamber (16 operational and 16 non-operational). The temperature extremes shall be -5°C to +85°C. The dwell time at each temperature extreme shall be 10 minutes. The transition time between each temperature extreme shall be 8 minutes. 100 thermal cycles shall be complete. There shall be no evidence of any electrical or physical degradation to the samples, as a result of the thermal cycling.
