Product Description

2.5Gbps DWDM SFP Optical Transceiver, 40km Reach

TAKFLY 2.5Gbps CWDM SFP Optical transceivers are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA). The transceiver consists of five sections: the LD driver, the limiting amplifier, the digital diagnostic monitor, the 1XX0nm DFB laser and the PIN .The module data link up to 40KM in 9/125um single mode fiber.
The optical output can be disabled by a TTL logic high-level input of Tx Disable, and the system also can disable the module via I2C. Tx Fault is provided to indicate that degradation of the laser. Loss of signal (LOS) output is provided to indicate the loss of an input optical 
signal of receiver or the link status with partner. The system can also get the LOS (or Link)/Disable/Fault information via I2C register access.

Features
  • Data-rate of 2.67Gbps operation
  • 18 CWDM DFB wavelengths laser and PIN or PIN photodetector for 40km transmis Compliant with SFP MSA and SFF-8472 with duplex LC receptacle
  • Digital Diagnostic Monitoring:
  • Internal Calibration or External Calibration Compatible with RoHS
  • +3.3V single power supply
  • Operating case temperature: Standard : 0 to +70°

Applications

Notes
  1. Circuit ground is internally isolated from chassis ground.
  2. Laser output disabled on TDIS>2.0V or open, enabled on TDIS<0.8V.
  3. Should be pulled up with 4.7k - 10kohms on host board to a voltage between 2.0V and 3.6V.MOD_DEF (0) pulls line low to indicate module is plugged in.
  4. This is an optional input used to control the receiver bandwidth for compatibility with multiple data rates (most likely Fiber Channel 1x and 2x Rates).If implemented, the input will be internally pulled down with > 30kΩ resistor. The input states are:
    1. Low (0 - 0.8V): Reduced Bandwidth
    2. (>0.8, < 2.0V): Undefined
    3. High (2.0 - 3.465V): Full Bandwidth
    4. Open: Reduced Bandwidth
  5. LOS is open collector output should be pulled up with 4.7k - 10kohms on host board to a voltage between 2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.
