company news about What are gigabit light modules and gigabit light modules? What's the difference?

It is well known that the main difference between gigabit module and gigabit module is that they have different transmission rates. The transmission rate of gigabit module is 1000Mbps, while that of ten-gigabit module is 10Gbps. In addition to the difference in transmission rate, do you know any other differences between the gigabit module and the gigabit module? In this article, FS will talk about the difference between a gigabit module and a gigabit module.

What is gigabit light module?

Gigabit optical module: The gigabit optical module is the optical module whose transmission rate is 1000Mbps. It is usually represented by FE, and there are two kinds of gigabit optical module: gigabit SFP optical module and GBIC optical module. The transmission distance can reach 80m -- 160km. In general, gigabit light modules can be identified from the specification details of the product itself and the naming rules for light modules provided by different companies.

What is the ten-megafilm module?

Megapixel module: A megapixel module is an optical module with a transmission rate of 10G, also known as a 10G optical module, which is packaged as SFP+ or XFP. IEEE 802.3AE, IEEE 802.3AK and IEEE 802.3AN are the standards for 10MB optical modules. When we choose 10MB optical modules, we can consider such factors as price, power consumption and space occupation.

How to distinguish gigabit light module from gigabit light module?

1. Classification differences between gigabit light module and gigabit light module:

Gigabit optical module includes 1000Base SFP optical module, BIDI SFP optical module, CWDM SFP optical module, DWDM SFP optical module, SONET/SDH SFP optical module and GBIC optical module.

Ten gigabyte optical modules include 10G SFP+ optical module, BIDI SFP+ optical module, CWDM SFP+ optical module, DWDM SFP+ optical module, 10G XFP optical module, BIDI XFP optical module, DWDM XFP optical module, DWDM XFP optical module, DWDM XFP optical module and 10G X2 optical module.

2. Application difference between gigabit light module and gigabit light module:

The gigabit optical module is used for gigabit Ethernet, dual-channel and two-way transmission synchronous fiber Network (SONET), while the gigabit optical module is used for gigabit Ethernet, STM-64 and OC-192 rate standard synchronous fiber Network (SONET) and 10G fiber channel.

3. Parameter differences between gigabit module and gigabit module:

(1) Parameters of gigabit light module:

Central wavelength: The central wavelength of the gigabit optical module mainly includes 1310nm, 1470nm, 1550nm, 1330nm-Tx /1270nm-RX

Of which, the optical module with a central wavelength of 1550nm is a single-mode optical module, and its transmission distance can reach more than 40km.

Transmission distance: The transmission distance of the gigabit modules varies from 20km to 120km, and most of the transmission distance of the gigabit modules is around 100km.

Interface: Except the INTERFACE of GBIC gigabit light module is SC duplex, the interface of other gigabit light modules is LC duplex.

Optical fiber type: The ten-megapixel module is usually used with single-mode fiber, so its optical fiber type is SMF.

Laser types: The laser types of gigabit light module mainly include DFB 1550nm, DFB BiDi, DFB 1310nm, DFB CWDM and DFB

DWDM.

DOM function: In the gigabit light module, except for GBIC light module which does not support DOM function, all other gigabit light modules support DOM function, which is the same as

GBIC light module is related to early light module.

(2) Parameters of 10MB light module:

Central wavelength: There are 1470nm, 1550nm, 1590nm, 1330nm-Tx /1270nm-RX in the central wavelength of 10MB optical module

BiDi optical module is 1330nm-Tx / 1270nm-Rx.

Transmission distance: The transmission distance of 10mb light modules varies from 20km to 80km, but most 10mb light modules are 80km.

Interface: The interface of XENPAK 10mb optical module is SC duplex, the interface of other 10MB optical modules is LC duplex.

Optical fiber type: The optical fiber type of gigabit module is SMF, just like the gigabit module.

Laser types: The laser types of 10mb optical module include EML 1550nm, DFB BiDi, EML CWDM, EML DWDM and DFB

For CWDM, we can get the information of its central wavelength or encapsulation type from the type of laser.

DOM function: Ten gigabytes of optical module with DOM function, this function can help the network administrator real-time monitoring optical module of all aspects of the data, the network

Administrators can also view this data to ensure that the light module is working properly.

Can the ten gigabyte light module be used on the gigabit switch?

If there is a ten-gigabit expansion port on the gigabit switch, you can use the ten-gigabit optical module. If not, you cannot use it. You must strictly follow the optical module and exchange

Select the appropriate light module at the port rate on the machine.

Conclusion:

Depending on your network type, you should choose whether to use a gigabit module or a gigabit module in your application. For example, if your network is a gigabit Ethernet, you should use gigabit

Module, ten gigabit Ethernet with ten gigabit light module. In addition, FS focuses on optical communication, and the gigabit module and the gigabit module supplied are both oversubscribed
