Description
Description:
The 1.25G SFP optical module is Small Form Factor Pluggable (SFP) transceivers are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA). They simultaneously comply with Gigabit Ethernet as specified in IEEE Std 802.31 and 1x and 2x Fiber Channel as defined in FC-PI 13.03.
The 1000BASE-LX/LH (long wavelength/long haul) SFP module interfaces fully comply with the IEEE 802.3z 1000BASE-LX standard.Their higher optical quality allows them to reach 6.2 miles (10 km) to 62.1 miles(100km) over single-mode fiber (SMF) .
Features:
- Up to 1.25Gb/s bi-directional data links
- Hot-pluggable SFP footprint
- 1310/1550nm FP/DFB, SM Fiber
- Duplex LC connector
- Very low jitter
- Up to 100km on 9/125μm SMF
- Metal enclosure, for lower EMI
- Single 3.3V power supply
- Low power dissipation <700mW typical
Application:
- Switch to switch interface
- High speed I/O for file servers .
- Bus extension applications

Notes:
- Non condensing.
- AC coupled.
- Or open circuit.
- Into 100 ohm differential termination.
- 20 – 80 %
- LOS is LVTTL. Logic 0 indicates normal operation; logic 1 indicates no signal detected.
- All transceiver specifications are compliant with a power supply sinusoidal modulation of 20 Hz to 1.5 MHz up to specified value applied through the power supply filtering network shown on page 23 of the Small Form-factor Pluggable (SFP) Transceiver MultiSource Agreement (MSA), September 14, 2000.
- Measured with DJ-free data input signal. In actual application, output DJ will be the sum of input DJ andDDJ.

Notes:
- Class 1 Laser Safety per FDA/CDRH and EN (IEC) 60825 regulations.
- Also specified to meet curves in FC-PI 13.0 Figures 18 and 19, which allow trade-off between wavelength, spectral width and OMA.
- Equivalent extinction ratio specification for Fiber Channel. Allows smaller ER at higher average power.
- Unfiltered, 20-80%. Complies with IEEE 802.3 (Gig. E), FC 1x and 2x eye masks when filtered.
- Measured with DJ-free data input signal. In actual application, output DJ will be the sum of input DJ andDDJ.
- Measured with conformance signals defined in FC-PI 13.0 specifications.
- Measured with PRBS 27-1 at 10-12 BER
