What is 40GBase-LR4 optical module?



The 40GBase-LR4 optical module is adopted QSFP+ package form with wavelengths of 1271, 1291, 1311 and 1331nm, duplex LC connector. The maximum transmission distance can reach 10km when used with OS2 singlemode patch cord.

Compatibility of HTF 40GBase-LR4 optical module

The 40G QSFP+ LR4 optical module provided by HTF  can be widely compatible with Huawei, Ruijie, H3C, Cisco, Juniper, ZTE and other brands of switches. The optical modules provided are subject to strict quality control and compatibility test before leaving the factory, so as to ensure that users receive high cost-effective optical modules.


Application of 40GBase-LR4 optical module

40GBase-LR4 optical module is widely used in 40G data center and metro optical transmission network.

The 40GBase-LR4 optical module can simplify the network architecture and reduce the number of accessories, so as to save the room area, reduce the equipment stack and improve the bandwidth management and scheduling ability of single node equipment. 40G optical module promotes the development of high-density and high-speed signal transmission, and makes optical communication enter a new era.

Introduction of 100G multi-mode optical modules—SR4/SRBD/SWDM4

Image
With the rapid development of 5G, AI, big data, cloud computing and other services, the data center network is required to develop in the direction of high speed, high density, and efficient operation and maintenance. At present, 100G is widely used in China. This article introduces three mainstream solutions for 100G multimode optical modules. 1) 100G QSFP28 SR4 Interface type: multi-mode MPO-12F working principle: The center wavelength of 100GBASE-SR4 is 850nm, which can provide four independent transmission and reception channels, and the operating rate of each channel can reach 25G. The transmission distance is 70m when used with OM3 multimode fiber and 100m when used with OM4 multimode fiber. 2) 100G QSFP28 SRBD Interface type: multimode duplex LC working principle The transmission wavelength of the 100GBASE-SRBD optical module is 850nm and 900nm, and the SWDM wavelength division multiplexing technology is used to multiplex the optical signals of different wavelengths in the same

800G Ethernet Coming Strong: Are You Ready?

Image
With the introduction of 400G optical modules, the interconnection of data centers is also gradually developing towards 800G Ethernet. The recent OFC 2020 conference in San Diego focused on 800G Ethernet, 800G technology and fiber jumpers for 800G networks, making 800G Ethernet another hot spot after 400G networks. However, 800G Ethernet is still being tested and perfected, and its large-scale deployment is still a long way off. 800G Ethernet and Optical module  standard Compared with 200G and 400G Ethernet, 800G Ethernet is a brand new technology. At present, several working groups have proposed specifications for 800G Ethernet. These specifications will be described in detail below. 1. The 800GBase-R will revert to 400G Ethernet technology for maximum cost savings Currently, the IEEE (Institute of Electrical and Electronics Engineers) does not have a standard for 800G Ethernet, but the 25G Ethernet Alliance (now known as the Ethernet Technology Alliance (ETC)) established the 800GBas

Introduction To The WDM

Image
  Synopsis The simultaneous transmission of two or more optical wavelength signals through different optical channels in the same optical fiber is called optical wavelength division multiplexing (WDM) technology. Reuse types Optical WDM includes frequency division multiplexing and WDM Optical frequency division multiplexing (FDM) technology and optical wavelength division multiplexing (WDM) technology have no obvious difference, because light wave is a part of electromagnetic wave. The frequency of light and wavelength has a single corresponding relationship. In general, optical frequency division multiplexing is a subdivision of optical frequencies. Optical channels are very dense. Wavelength division multiplexing (WDM) refers to the coarse division of optical frequency, the optical channels are far apart, and even in different Windows of the fiber. Structure Wavelength division multiplexer and demultiplexer (also known as combined wave/splitter) are placed on both ends of the optical
