The function and characteristics of PDH optical transceiver
PDH optical transceiver (Plesiochronous Digital Hierarchy), a quasi-synchronous digital transmission series system. PDH optical transceivers are small-capacity optical transceivers. PDH optical transceivers are generally used in pairs, also called point-to-point applications. The capacity is gene...Read more -
Is the telephone optical transceiver easy to use?
Is the telephone optical transceiver easy to use? Of course it is easy to use, otherwise it will not be a product of the historical development of communication equipment! Telephone optical transceiver is a device that converts traditional telephone signals into optical signals and transmits them...Read more -
What are the interface types of the telephone optical transceiver?
The commonly used telephone interface types of telephone optical transceivers are: loop relay interface (FXO), analog subscriber line interface (FXS), hotline telephone interface (official telephone), magnet telephone interface. Telephone optical transceivers are used in pairing. The telephone in...Read more -
Introduction to the applicable environment of the 8-port PoE Switch
8-port POE network switch “Never burn device” smart POE switch, advanced self-sensing algorithm only powers IEEE 802.3af terminal equipment, so there is no need to worry about damaging private standard PoE or non-PoE equipment. Intelligent power supply system, overload protection, bre...Read more -
8-port poe switch product introduction
The eight-port POE switch ( JHA-P30208CBMH) provides power and data transmission using Category 5 Ethernet cables from a network node. 8+2 port fast Ethernet ports can be used for 10/100Mps connection, of which 8 ports can provide industry standard IEEE802.3af power. The advanced self-sensing al...Read more -
How to test the compatibility of compatible optical modules?
People who often buy optical modules know that optical fiber modules usually need to confirm the compatibility code, because there are currently two types on the market, one is a high-performance compatible module, and the other is an optical module of the original switch brand. The price gap bet...Read more -
How to realize POE power supply for ordinary switches?
PoE switch refers to a switch that can provide network power supply to remote powered terminals through a network cable. It is a relatively common power supply device in PoE power supply systems. However, if a switch does not have a POE function, can an additional poe power supply module be added...Read more -
Introduction to the use of optical modules
Optical module, especially refers to the small packaged optical module that can be hot-swapped. It is the optical module that can be hot-swapped during operation and used on the device port. It is mainly used to connect the device (generally refers to the switch or router device). The electrical ...Read more -
Which is better to use CWDM/DWDM Multiplexer?
CWDM/DWDM wavelength division multiplexing equipment usage As people’s requirements for bandwidth are getting higher and higher, Dense Wavelength Division Multiplexing (DWDM) devices have made great progress in reducing costs, and are therefore more and more favored in the market. However, ...Read more -
What is the difference between CWDM/DWDM Multiplexer?
In the construction of metropolitan area networks (especially long-distance OTN optical transmission networks), wavelength division multiplexing equipment is particularly important. DWDM dense wavelength division multiplexing equipment has long-distance, high-bandwidth transmission capabilities; ...Read more -
What causes the RS485 converter signal to be interfered?
The main function of the 485 converter is to convert a single-ended RS-232 signal into a balanced differential RS-485 or RS-422 signal. Due to long-distance information transmission and strong anti-interference ability, rs485 converters are widely used in security communication and other fields. ...Read more -
What are the reasons for the failure of the optical module?
The optical module is mainly used to convert the electrical signal in the device (usually referring to the switch or router device) into an optical signal, and then transmit it through an optical fiber (implemented by the transmitting end of the optical module), and can receive an external optica...Read more
