Frequently Asked Questions
Q: What is an SFP BIDI transceiver and how does it work?
An SFP BIDI (Bidirectional) transceiver is an optical module that uses Wavelength Division Multiplexing (WDM) technology to transmit and receive data over a single strand of optical fiber. This is done by operating at two different wavelengths (for example, TX 1310nm / RX 1550nm).
Q: Do SFP BIDI modules need to be deployed in matching pairs?
Yes, BIDI transceivers must always be used in complementary pairs. If you install a T13/R15 module (transmitting at 1310nm and receiving at 1550nm) at one end of the link, you must install a matching T15/R13 module (transmitting at 1550nm and receiving at 1310nm) at the opposite end.
Q: What types of connectors and fiber cables do these modules support?
These SFP BIDI modules are designed with a simplex LC connector interface and are engineered for Single-Mode Fiber (SMF) installations to achieve optimal transmission distances.
Q: What is the difference between FP and DFB lasers listed in the table?
FP (Fabry-Perot) lasers are generally used for shorter transmission distances (such as 3km to 20km) due to wider spectral width, whereas DFB (Distributed Feedback) lasers offer narrower spectral width and are preferred for longer reach applications (40km up to 160km).
Q: What does the "D" suffix in the Part Number signify?
The "D" suffix typically indicates that the transceiver supports Digital Diagnostics Monitoring (DDM) / Digital Optical Monitoring (DOM), allowing real-time monitoring of parameters like optical power, temperature, and voltage.
Q: How can I obtain the detailed datasheet for a specific model?
You can easily download the comprehensive technical specifications by clicking the "DOWNLOAD" button next to the respective Part Number in our ordering information table above.
