Cisco 10G SFP Module

The Cisco 10G SFP Module is a cost-saving 10G connection solution. The 10G optical port to electrical port module is also called the 10G SFP+ electrical port module. This module is specially designed for high-speed communication links. Compared with ordinary optical modules Generally speaking, the power consumption of 10G optical to electrical modules is half of that of ordinary optical modules, and its performance is stable. It can realize 10G transmission network through network cables and is widely used in 10G Ethernet.

1. There is a choice of multi-rate or single-rate. There are 10G rate electrical interface modules that support multiple rates (1-10Gb/s), and some that only support a single rate (10Gb/s).

2. The operating temperature range is different. 10G electrical port modules are available in commercial grade and industrial grade. The working temperature range of commercial grade is 0-70℃, and the working temperature range of industrial grade is -45-80℃.

3. Use different main chips.

Application scenarios of 10G SFP+ electrical port optical modules:

RJ-45 and SFP+ module interfaces cannot be directly interconnected. A SFP+ module to RJ45 interface converter is required. The 10G electrical port module is such a converter. Through the 10G electrical port module and Cat6 network cable, the 10G electrical port network card with RJ-45 interface can be interconnected with the 10G switch with SFP+ interface.

How to use: First insert the 10G electrical port optical module into the 10G switch with the SFP+ interface, and then directly use the network cable of the RJ45 interface to successfully connect the 10G network card and the 10G switch.
 

Q: What are the relevant parameters and differences between SFP and SFP+ optical modules?

First of all, we need to understand the various parameters of the optical module, of which there are three main ones (center wavelength, transmission distance, transmission rate). The main differences between optical modules are also reflected in these points.

1. Central wavelength

The unit of central wavelength is nanometer (nm), and there are currently three main types:

1) 850nm (MM, multi-mode, low cost but short transmission distance, generally only 500m);

2) 1310nm (SM, single mode, with large loss but small dispersion during transmission, generally used for transmission within 40km);

3) 1550nm (SM, single mode, with small loss but large dispersion during transmission, generally used for long-distance transmission of more than 40km, and can directly transmit up to 120km without relay).

2. Transmission distance

Transmission distance refers to the distance that optical signals can be transmitted directly without relay amplification, in kilometers (also called kilometers, km). Optical modules generally have the following specifications: multi-mode 550m, single-mode 15km, 40km, 80km and 120km, etc. wait.

3. Transmission rate

The transmission rate refers to the number of bits (bits) of data transmitted per second, in bps. The transmission rate is as low as 100Mbps and as high as 100Gbps. There are four commonly used rates: 155Mbps, 1.25Gbps, 2.5Gbps and 10Gbps. The transmission rate is generally downward. In addition, optical modules in optical fiber storage systems (SAN) also have three rates: 2Gbps, 4Gbps and 8Gbps.
