Bidi (Bidirectional) SFP is a single fiber two -way light module, also known as WDM light module. It uses WDM technology to realize the two -way transmission of optical signals on a fiber.
The BIDI light module has only one port. The filter is filtered through the filter in the light module. At the same time, the launch of the 1310Nm light signal and the receiving of the 1550nm light signal, or the opposite. Therefore, the module must be used in pairs. His biggest advantage is to save fiber resources.
What are the differences between Gigabit BIDI and Mallimony BIDI? Let's take a look together!
1. rate
The transmission rate of Gigabit BIDI is 1.25G, and the transmission rate of 10G BIDI is 10G. What is the relationship between them? Their relationship is very simple, 10 times that of the Vigabit BIDI is 10 times that of the Gigabit BIDI rate.
2. Appearance
3. Band
Gigabit BIDI: TX1310/RX1550NM, TX1550/RX1310NM, TX1310/RX1490Nm, TX1490/RX1310Nm, TX1490/RX1550NM, TX1550/RX1490Nm
Mark Bidi: TX1270/RX1330NM, TX1330/RX1270Nm
4. Transmission distance
Gigabit BIDI can be transmitted to 120km longest distance, while 10,000 -Dibin BIDI can only be passed to 80km. what is the reason? The master will tell you, because there is no light device (o (∩_∩) o haha ~)
5. Application on the switch has requirements
The corresponding switch light in the Gigabit BIDI is the SFP Light Pass, and the switch light port corresponding to the 10D BIDI is the SFP+Light mouth
