Magneto optical switch is an optical switch using Faraday magneto-optic effect. The effect of magneto-optic crystal on the polarization plane of incident polarized light is changed by the change of external magnetic field, so as to achieve the effect of optical path switching. #magnetopticalswitch #ultrafastopticalswitch #fastopticalswitch #fiberswitch #magneticswitch https://www.glsunmall.com/product/csw-1x2b-magneto-optical-switch.html
OTDR under the control of the precise clock circuit, according to the set parameters to send optical pulse signal to the optical port, and then OTDR continuously according to a certain time interval from the optical port to receive the optical signal reflected back from the fiber, respectively, according to the Rayleigh backscattering (test optical fiber loss) and Fresnel reflection (test optical fiber reflection) principle of the corresponding test of the fiberhttps://www.glsun.com/product-v93-ots3000-otdr-optical-time-domain-reflectometer.html

Fiber optic network switch, or fiber switch, is
a multi-port telecommunication network bridge device to connect multiple optic
fibers to each other and controls data packets routing between inputs and
outputs. More exactly, a fiber optic network switch receives a message from any
device connected to it and then transmits the message only to the device for
which the message was meant. This makes the fiber optic switch a more
intelligent device than a hub (which receives a message and then transmits it
to all the other devices on its network). The fiber Ethernet switch plays an
integral part in most modern Ethernet local area networks (LANs). Mid-to-large
sized LANs contain a number of linked managed switches. #fiberopticswitch

MEMS optical switch is based on micro-electro-mechanical
system, which uses optical micro mirrors or optical micro-mirror arrays to
change the propagation direction of light beam to achieve optical path
switching. The working principle of MEMS optical switch is quite simple. When
the optical switching is carried out, the angle of MEMS micro mirror is moved
or changed by electrostatic force or magnetic force, and the input light is
switched to different output ends of the optical switch to realize the
switching and on-off of the optical path.#MEMS #MEMSOPTICALSWITCH

The erbium-doped fiber (EDF) is at the core of
EDFA technology, The erbium-doped fiber in the
erbium-doped fiber amplifier is doped with erbium element, and the erbium-ion
energy is high and very unstable, and it is easy to jump to the low energy
level through various ways. Under the energy transmission of the pump source, a
large number of erbium-ion stacks and then realize the inversion of the
particle number, creating conditions for stimulated radiation.

GLSUN optical transmission system is mainly composed of transmitter, transmission medium, and receiver. It offers kinds of highly efficient transmission by using optical transmission technologies in accordance with different applications for networking solutions.
The data rate of optical modules has upgraded from 100 Mbps to 1 Gbps to 10G, 25G, 100G and even 400G for development of fiber optic communication. Among them, SFP28 transceiver module is an optical module with a transmission rate of 25Gbps. SFP28 stands for small form-factor pluggable 28. It features low power consumption, high port density and can save the cost of network deployment, so it is widely used in 25G Ethernet and 100G (4X25Gbps) Ethernet.
Advantages of 25G SFP28 Transceiver Modules
1. Compared with 100G optical modules, SFP28 modules have lower loss.
2. Compared with 40G optical modules, SFP28 modules are more cost-effective. SFP28 modules can adopt two fiber channels to achieve 50G transmission rate, while 40G modules need four 10G fiber channels to achieve 40G transmission rate
3. Compared with 10G optical modules, SFP28 modules have 2.5 times the optical input/output performance that of 10G modules, and feature higher port density, thus can save operating costs by reducing the number of ToR switches and cable.
Categories of 25G SFP28 Modules
There are mainly 2 types, SFP28-25G-SR, and SFP28-25G-LR.
They are compliant with IEEE 802.3, SFF-8472, SFF-8402, SFF-8432, SFF-8431 and other standards. It is an SFP28 optical module with center wavelength of 850nm, supporting DOM (Digital Optical Monitoring) function to help manage the real-time monitoring of optical modules. Its difference from other SFP28 optical modules lies in its transmitter type - VCSEL (vertical-cavity surface-emitting laser), so it requires the use of 50/125µm MMF OM3/OM4 patch cables. The SFP28-25G-SR modules are sui for short-distance data transmission (max. 100m) and can be used in 25G Ethernet switches, routers, network interface cards (NIC) and storage network devices.
They are also compliant with IEEE 802.3, SFF-8472, SFF-8402, SFF-8432, SFF-8431 and other standards. It is an SFP28 optical module with center wavelength of 1310nm, and its maximum transmission distance can reach up to 10km being used together with single mode fiber, therefore SFP-25G-LR modules are mainly used in long distance transmission (max. 10km). Its difference from SFP-25G-SR modules lies in that it uses DFB laser transmitter.
