10 / 30 page V23848-C18-C56 V23848-C19-C56 Technical Data Data Sheet 10 2004-06-25 Optical Characteristics ( V CC = 2.97 V to 3.63 V, TC = –40°C to 85°C) Parameter Symbol Values Unit min. typ. max. Transmitter Launched Power (Average) 1) 1) Into single mode fiber, 9 µm diameter. P O –15 –8 dBm Extinction Ratio (Dynamic) ER 8.2 dB Center Wavelength λ C 1270 1355 nm Spectral Width (rms) σ I 2.5 nm Tx Disable Laser Output Power P O-TxDis –50 dBm Optical Eye Mask 2) 2) Transmitter eye is according to ITU-T G.957 S-1.1 and SONET OC-3 IR-1. Measured with 10% eye mask margin. According to standards Jitter Generation (pk-pk) 3) 3) The transceiver is specified to meet the SONET/SDH Jitter performance as outlined in ITU-T G.958 and Telcordia GR-253. Jitter Generation is defined as the amount of jitter that is generated by the transceiver. The Jitter Generation specifications are referenced to the optical OC-3 signals. If no or minimum jitter is applied to the electrical inputs of the transmitter, then Jitter Generation can simply be defined as the amount of jitter on the Tx optical output. The SONET specifications for Jitter Generation are 0.01 UI rms, maximum and 0.1 UI pk-pk, maximum. For SDH, 10 mUI rms, maximum. Both are measured with a 12 kHz - 1.3 MHz filter in line. A UI is a Unit Interval, which is equivalent to one bit slot. J pk-pk Tx 0.033 0.045 UI Jitter Generation (rms) 3) J rms Tx 0.001 0.0025 UI Rise Time 4) 4) Values are 20% - 80%, filtered and measured at nominal data rate. t R-Tx 40 ps Fall Time 4) t F-Tx 155 ps Receiver 5) 5) Receiver characteristics are measured with a worst case reference laser. Saturation (Average Power) 6) 6) At 9 dB Extinction Ratio of the incoming signal. P SAT –8 dBm Sensitivity (Average Power) 7) @ 155 Mbit/s @ 125 Mbit/s @ 10 Mbit/s 8) P IN –32 –32 –35 –28 –28 –28 dBm LOS Assert Level 9) P LOSA –39 dBm LOS Deassert Level 9) P LOSD –30 dBm LOS Hysteresis 9) P LOSA – P LOSD 0.5 3 dB Input Center Wavelength λ C 1260 1580 nm |
