  • FP laser transmitter for 1310/1550nm DFB laser transmitter for 1550/1310nm
  • PIN photo-detector
  • BIDI SC/UPC type pluggable optical interface
  • Metal enclosure, for lower EMI
  • RoHS compliant and lead-free
  • Compliant with SFF-8472,Support Digital Diagnostic Monitoring interface
  • Single +3.3V power supply
  • Case operating temperature: Commercial: 0°C to +70°C, Extended: -10°C to +80°C, Industrial: -40°C to +85°C


The DDM SC 40KM 1.25G BIDI Module SFP 1310nm(tx)/1490nm(rx) 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.


Every sfp bidi transceiver module is individually tested on full range of Hilink equipments, walks through the testing challenges and 100% compatibility.
