Optical Parameters Parameter Symbol Min Typ Max Units Notes/Conditions TRANSMITTER CHARACTERISTICS Center Wavelength Spacing 100 GHz Corresponds to approximately 0.8 nm Spectral Width ∆λ 20 0.2 0.3 nm Full width, -20dB from max Transmitter Center Wavelength – End of Life λ c X - 100 X X + 100 pm X = specified ITU center wavelength Transmitter Center Wavelength – Start of Life λ c Y - 25 Y Y + 25 pm Y = specified BOL center wavelength Side Mode Suppression Ratio (SMSR) SMSR 30 dB Modulated Optical Rise/Fall Time tr / tf 160 ps Unfiltered, 80% -20% Transmitter Optical Output Power Pout 0 +4 dBm Average power coupled into single mode fiber Transmitter Extinction Ratio OMI 8.2 dB Transmitter Eye Opening 10 % OC-48 eye mask margin Transmitter Jitter (peak to peak) 75 mUI Parameter per GR-253 8 section 5.6 for OC-48 B Tolerable Back Reflection BR -14 dB See note 5 Relative Intensity Noise RIN -120 dB/Hz Dispersion Power Penalty at 120km 3.0 dB 2400ps/nm. See Note 3. RECEIVER CHARACTERISTICS Optical Input Wavelength Pin 1520 1570 nm Receiver Jitter Generation 75 mUI Parameters per GR-253 8 section 5.6 for OC-48 B Optical Input Power (BER < 10 -9) Pin -30 -9 dBm 2.5 Gb/s w/ PRBS 2 23 -1 Optical Input Power (BER < 10 -12) Pin -28 -9 dBm 2.5 Gb/s w/ PRBS 2 23 -1 Optical Input Power – Receiver Damage Threshold 6 dBm Receiver Reflectance RRX -27 dB OSNR Limit OSNRmin 20 dB OSNR Power Penalty 3.0 dB For OSNR = OSNRmin. See Note 4 Notes: 1. Parameters are specified over temperature and voltage, at end of life unless otherwise noted. 2. All parameters are measured on a Finisar SFP Evaluation Card unless otherwise noted. 3. Dispersion power penalty is measured in loop back with OSNR set at Rx < 28 dB. Data rate and pattern used same as specified for Optical Input Power. Dispersion penalty is measured at BER = 10 -10 4. OSNR power penalty is measured in loop back. Data rate and pattern used is same as specified for Optical Input Power. OSNR penalty is measured at BER = 10 -10 5. Tolerable back reflection is the max back reflection level at which the power penalty will be <1dB. Power penalty is measured over fiber (2400ps/nm) at BER = 10 -10 under high OSNR (>28dB) conditions. |
