There are many different transmission rates and transmission distances for optical modules, so when we select fiber patch cord for optical modules, we need to select the type of fiber patch cord that matches it. Otherwise, it will cause unnecessary waste or loss. So what kind of optical fiber patch cord is used for different optical modules? Let's talk about it!

ETU-LINK 1.25G optical module

It refers to the optical module with a transmission rate of 1.25G. Its package form is SFP, and it can be transmitted to 160km at most. Then how can 1.25G be connected with optical fiber patch cord? Here are two examples:

1. The working wavelength of 1.25G SFP SX optical module is 850nm. It adopts LC duplex interface, and the transmission distance can reach 550m when it is used with OM1/OM2 multi-mode dual fiber optical patch cord.

2. The working wavelength of 1.25G SFP LX module is 1310nm. It adopts LC duplex interface, and the transmission distance can reach 10km when used with OS2 single-mode dual fiber optical patch cord.

ETU-LINK 10G optical module

Refers to the optical module that can send and receive 10G data signals per second. According to the different packaging, 10G Optical module can be divided into XENPAK optical module, X2 optical module, XFP optical module and SFP+ optical module. At present, 10G SFP+ optical module is more popular.

1. The working wavelength of 10G SFP+ LR optical module is 1310nm. With LC duplex interface, the transmission distance can reach 10km when used with OS2 single-mode dual fiber optical patch cord.

2. The working wavelength of 10G SFP+ SR optical module is 850nm. It adopts LC duplex interface, and the transmission distance can reach 300m when it is used OM3 with multi-mode dual fiber optical patch cord.

ETU-LINK 40G optical module

It refers to the optical module with a transmission rate of 40G. Its package forms are CFP and QSFP+, which are mainly used for backbone network transmission. 40G QSFP+ optical module is one of the most widely used optical modules, but it has many models. Let's list the types of optical fiber patch cord corresponding to 40G QSFP+ SR4 optical module.

The working wavelength of the 40G qsfp SR4 optical module is 850nm, and MPO connector is used. The transmission distance is 100m when it is used with OM3 multimode fiber patch cord and 150m when it is used with OM4 multimode fiber patch cord.

ETU-LINK 100G optical module

The transmission rate of 100G optical module is 100G. The main types of 100G optical module launched on the market are: CXP optical module, CFP optical module, CFP2 optical module, cfp4 optical module and QSFP28 optical module. QSFP28 optical module is widely used in the market.

The working wavelength of 100G QSFP28 LR4 optical module is 1295.56-1309.14nm, adopting CWDM transmission technology and LC duplex interface. The transmission distance can reach 10km when connected with single-mode dual fiber OS2 fiber patch cord.

In general, multimode optical modules are used with multimode fiber patch cords, and vice versa. Generally, with the same transmission rate, the corresponding transmission distance of optical modules with different operating wavelengths is also different. Thank you for your support!
