What are the application and protection of the light module.epon onu huawei compatible manufacturer

With the development of science and technology and the construction of 4G networks, the requirements for transmission rates are getting higher and higher, and people's speed of signal networks is getting higher and higher. Therefore, a high -speed transmission equipment product is needed, which generates a 10G light module.

Optical module: The integrated module of the optical transmission is composed of optoelectronics equipment, function circuits, and optical interfaces, including launch and receiving. That is, light and sending all -in -one module. To put it plainly, the light module is electricity. Electronic products with light conversion can convert signals into optical signals to make the transmission distance more transport.

There are currently three main types of nano (NM):

850nm (mm, multi -mode, low cost but short transmission distance, generally only 500m can be transmitted); 1310nm (SM, single mode, large loss during transmission process, but generally used for transmission within 40km);

1550nm (SM, single -mode, small loss during transmission process, which is generally large, generally used for long -range transmission above 40km, which can be directly transmitted by 120km);

Bit (BIT), unit BPS transmitted per second.

Currently commonly used: 155Mbps.1.25Gbps.2.5Gbps.6Gbps.10Gbps, etc. The transmission rate is generally compatible with downward, so the 155M light module is also called the FE (100M) light module. The 1.25G light module is also called the GE (Gigabit) light module. It is currently the most widely used module in the optical transmission equipment. In addition, in the optical fiber storage system (SAN), its transmission rate is 2Gbps.4Gbps.6Gbps and 8Gbps.

Transmission distance.

The distance between the light signal can be directly transmitted to the relay enlarged, the unit kilometers (also known as the kilometer, kilometers). The light module generally has the following specifications: 550m multi -mode, 15km single mode, 40km, 80km, 120km, etc.
