4 / 13 page 2× 5/2×10 SFF GEPON OLT Transceiver FTM-9712P(T)-F(K)20(G) 20km transmission Preliminary Data Sheet Mar. 20, 2007 Fiberxon Proprietary and Confidential, Do Not Copy or Distribute Doc No: DS3513000-1d Page 4 of 13 Note 7: TX_DIS (See Pin Function Definitions) Note 8: LAS_nFAIL, for FTM-9712P(T)-K20(G) (See Pin Function Definitions) Table 5 - Receiver Optical and Electrical Characteristics (0°C <TOPR<70°C and 3.13V<VCC<3.47V) Parameter Symbol Min. Typical Max. Unit Notes Operating Wavelength 1260 1360 nm Sensitivity PSEN -30 dBm Saturation PSAT -6 dBm 1 Receiver Threshold Settling Time TSETTLING 250 ns 1,2 Dynamic Range -30 -6 dBm 1,3 Signal-Detected Assert Level PSDA -31 dBm 4 Signal-Detected Deassert Level PSDD -45 dBm 5 Signal-Detected Hysteresis PSDA- PSDD 0.5 6 dBm Receiver Reflectance -12 dB Power Supply Current ICC_RX 120 mA Data Output Voltage - Low VOL-VCC -1.81 -1.62 V Data Output Voltage - High VOH-VCC -1.02 -0.88 V Data Output Differential Swing VOUT 400 1600 mV 6 Signal-Detected Voltage - Low VSD, L 0 0.4 V Signal-Detected Voltage - High VSD, H 2.4 VCC V 7 Signal-Detected Assert Time TASS 1.2 µs Signal-Detected Deassert Time TDAS 0.5 µs Note 1: Measured with a PRBS 2 7-1 test pattern @1.25Gbit/s and ER=10dB, BER =10-12. Note 2: See Figure 1,2. For multiple ONUs application, It isn’t easy to test TSETTLING directly, but there is a relationship TSETTLING = TGAP-TGUARD when TON=TOFF, then TSETTLING can be calculated by TGAP and a certain guard time at ONU side. Note 3: See Figure 3. TGAP be less than 250ns is guaranteed. Note 4: An increase in optical power above the specified level will cause Signal-Detected (SD) output to switch from a low state to a high state. Note 5: A decrease in optical power below the specified level will cause Signal-Detected (SD) output to switch from a high state to a low state. Note 6: LVPECL output, DC coupled internally, guaranteed in the full range of input optical power (-6dBm to -31dBm) (See Recommended Interface Circuit) Note 7: SD (See Pin Function Definitions) |
