We know that optical modules can be divided into single-mode optical modules and multimode optical modules are usually marked on the module. Single mode to SM, for long-distance transmission, fiber color is yellow; multi-mode is MM, usually used for short-distance transmission, fiber color is orange

H3C S5500-28C-SI is a Gigabit Ethernet switch developed by H3C. It has special cluster management functions, multi-service support functions and security functions for large enterprise networks. And the access or aggregation of the campus network and the connection of the data center server farm.1.

The Huawei S5700-28P-PWR-LI-AC switch is a new generation of green, energy-efficient Gigabit Ethernet switches introduced by Huawei that can meet the needs of large broadband access and Ethernet multi-service development. This switch uses a high-performance hardware chip, with large capacity, high-d

H3C S5120-SI series switches are widely used in the access layer Gigabit Ethernet switches, with a flexible Gigabit access and intelligent resilience architecture features is seen as the ideal of Gigabit access select. This article will focus on H3C S5120-SI series switches and their SFP optical mod

As the data center area and data transmission rate is growing, people need a minimum distance of 500m transmission distance of 100G optical module solution, based on this, 100GBASE-PSM4 QSFP28 light module came into being, it is a Single-mode parallel optical module, can provide cost-effective long-

Today, 40G network has gradually developed into a backbone network for long-distance network transmission applications. And the 40G QSFP+ SR4 optical module is widely used in 40G short-range network transmission. In general, 40G QSFP + SR4 optical module can work in the 850nm wavelength environment,

In the field of optical communications, there are many devices with similar functions. For example, optical modules and fiber media converter are equipment for photoelectric conversion, and sometimes they have different names. Optical module is also known as optoelectronic module while fiber media c

The rapid growth of the data center requires the server with higher performance. From the initial 100M, 1G, 10G, to 40G and 100G, high-speed Ethernet has never stopped developing. The 10G Ethernet (IEEE802.3ae) standard was approved in 2002. In the 10G network, engineers are often confused about cho

As a widely used and powerful optic component, optical modules are irreplaceable in fiber optic communication. With the increase of demands for bandwidth and performance of fiber optic communication and network system, the types and performance of optical modules are getting rich and strong, how to
