Quick Answer
Start with the target device, port, link distance, fiber type and document needs. Then use the article content below to narrow the model path before sending an RFQ.
BIDI SFP is a bidirectional optical module, also called WDM module. It uses WDM technology to realize the bidirectional transmission of optical signals on one optical fiber. BIDI module only has 1 port, wave filtering through the filter of module, and finished the transmitting of 1310nm optical signal and receiving of 1550nm optical signal, or opposite. Therefore the module must be used in pairs. Its biggest advantage is to save fiber resources. What are the differences between the Gigabit BiDi and 10Gigabit BiDi module? Let's learn about it! Data rate Gigabit BiDi transmission rate is 1.25G, 10Gigabit BiDi is 10G. The latter is 10 times of the former Appearance Wavelength Gigabit BiDi：TX1310/RX1550nm，TX1550/RX1310nm，TX1310/RX1490nm，TX1490/RX1310nm，TX1490/RX1550nm，TX1550/RX1490nm 10Gigabit BiDi：TX1270/RX1330nm，TX1330/RX1270nm Transmitting distance The longest distance of Gigabit BiDi is up to 120KM, while 10Gigabit BiDi is 80KM. The requirements of application on the switch The switch port for Gigabit BiDi is SFP port, for 10Gigabit BiDi is SFP+ port.
