Nowadays, optical transceiver network devices are increasingly used in our network engineering. They are used in small-scale optical fiber trunk connection solutions, so it is better to use optical fiber interfaces for switches in large-scale optical fiber trunk. Because of the various types of optical fiber, wavelength, interface type, rate, and other technical indicators, a wide range of Optical Fiber transceive
In the domestic common information development and implementation projects, most of the work of the development of the workload is concentrated in order to adapt to different customer needs, the specific modules to modify, and ultimately achieve customer expectations of the software functional characteristics. But for the development of vendors, in the face of different customers to develop different software versions, will lead to duplication of labor, cost rise, maintenance incre

Four Gtxe2_channel Primitives and one Gtxe2_common primitive to be a Quad.The
"Netizen asks a question": have been not clear exactly what difference does photoelectric converter, fiber transceiver, light cat, light module have?
"Answer": Optical module is inserted in the router or switch, can not be used independently, belong to other devices part.
and netizens mentioned (photoelectric converter, optical transceiver, light cat, optical module) A few things are basically one thing,
In the wireless data transmission system, the wireless transceiver chip is the core carrier of the technology. As the signal sending and receiving, modulation, and debugging, it plays an absolute core role. We will compare and analyze several Wireless Transceiver Chip Solutions.
1) CC1000 Wireless Transceiver Chip Solution
CC1000 is a single-chip programmable RF
When using a fiber-optic transceiver, it is necessary to pay attention to some problems in order to make the use of fiber-optic transceiver better.
1. View whether full duplex or half-duplex is supported.
Some of the market can only use a full dual public environment, can not support Half-duplex, such as receiving other brands of switches or hubs, and it uses Half-duplex mode, otherwise it will cau
