1. SFP modules consist of:laser: including transmitter TOSA and receiver ROSA, circuit board IC, and the external parts include: shell, base, PCBA, pull ring, clasp, unlocking piece, rubber plug.
In addition, for the convenience of identification, the color of the ring is generally used to identify the module's parameter types. For example, the black pull ring is multimode, the wavelength is 850 nm; the blue is the module with the wavelength of 1310 nm; the yellow is the module with the wavelength of 1550 nm; the purple is the module with the wavelength of 1490 nm.
2. How does the BIDI SFP module work?
In order to work efficiently, BIDI SFP modules must be paired to achieve bidirectional transmission of data by tuning the duplexer to match the desired wavelength of the transmitter and receiver.
3. What is the difference between SFP and BiDi SFP ?
As is well known, a common SFP module usually has two ports, one for the TX port to transmit signals and the other for the RX port to receive signals. Unlike common SFP modules, the BiDi SFP module has only one port that uses an integral WDM coupler to transmit and receive signals on a single fiber.
FAQ
1、Question：I wish to connect two switches in my network rack. I can use the 1000BASE-T RJ45 connectors or SFP. Why should I consider using SFP?
Answer：The backplane on the switches may be designed so that the SFP ports have dedicated bandwidth specifically designed to cross-connect switches. A “uplink port”, so to speak. If that’s the case, you will get better throughput and lower latency between switches using the SFP ports because they’re configured differently on the backplane but not necessarily because of the ports themselves.
2、Question：What Is Multimode SFP?
Answer：Multi-mode thread (MMF) uses a very large core and usually uses more wavelengths. Therefore, the optics used in the MMF has the ability to collect light from the laser. In practice, this means that the optics is cheaper. The generic multimodal SFP (MMF SFP) runs along the 850nm wavelength and is only used for a short distance transduction in the range of 100m to 500m. Although it cannot walk long distances, many types of optical alarms can be transported.
