Frequently Asked Questions (FAQ)
Q: What is an SFP BIDI transceiver?
An SFP BIDI (Bidirectional) transceiver is a compact optical transceiver module that uses Wavelength Division Multiplexing (WDM) technology to transmit and receive data over a single optical fiber strand by using different wavelengths.
Q: What transmission distances are supported by these SFP BIDI modules?
Depending on the specific part number selected, these 1.25G SFP BIDI modules support transmission distances ranging from short-range 3KM up to ultra-long-range 160KM over single-mode fiber (SMF).
Q: What wavelength pairings are used in these transceivers?
These modules must be used in pairs with matching complementary wavelengths, such as T1300nm/R1550nm (TX1310/RX1550) paired with T1550nm/R1300nm (TX1550/RX1310), or T1490nm/R1550nm paired with T1550nm/R1490nm.
Q: What connector type and operating temperature range do these modules support?
All the listed SFP BIDI modules utilize a simplex LC connector interface and are rated for commercial operating temperatures ranging from 0°C to 70°C.
Q: What is the difference between FP and DFB lasers used in these modules?
FP (Fabry-Perot) lasers are typically used for shorter distances (like 3KM to 20KM) due to higher spectral width, whereas DFB (Distributed Feedback) lasers are utilized for longer distances (up to 160KM) because of their narrower spectral width and better performance over long spans.
