PowerPort TM 2040/2140 TRX 10 Gb/s XFP Transceiver for 40km TDM & DWDM Applications ABSOLUTE MAXIMUM RATINGS 1 Parameter Symbol Min Max Unit Optical input Power Damage Threshold +3 dBm Supply Voltages Vcc5 0 +6.0 V Vcc3 0 + 3.6 V Vcc2 0 +2.0 V Data AC Voltage Differential Tx+, Tx- 0 +2.0 Vpp Control Input Voltage 0 Vcc3 V Storage Temperature TSTG -40 +85 °C Note 1: Exposing the device to stresses above those listed in absolute maximum rating could cause permanent damage. The device is not meant to operate under conditions outside the limits described in the operational sections of this specification. Exposure to absolute maximum rating conditions for extended periods may adversely affect device reliability.

Typical values are referenced to +25 °C, nominal power supply, beginning of life. Optical characteristics are guaranteed with up to –24dB line optical return loss. Note 2: For Tx/Rx pair, penalty includes chromatic dispersion, PMD, reflections, and jitter effects and an OSNR >30dB. There is an additional penalty for lower OSNR. Note 3: Measured @BER 10 -12 and under modulation conditions NRZ at 9.953 Gb/s and PRBS 2 23 -1. Note 4: Measured in accordance with the XFP MSA Rev. 4.5. Note 5: Measured @BER 10 -12 and under modulation conditions NRZ at 9.953 Gb/s and PRBS 2 23 -1. AFR20400408 2
