Fiber Transceiver Features and How to Choose Fiber Transceivers

Fiber-optic transceivers are generally used in the actual network environment where Ethernet cables cannot cover and must use optical fiber to extend the transmission distance. At the same time, they also play a huge role in helping to connect the last mile of optical fiber to the metropolitan area network and the outer network. The role. With fiber optic transceivers, there is also a cheap solution for users who lack the capital, labor, or time to upgrade the system from copper to fiber.

Basic features of fiber optic transceivers :

1. Provide ultra-low latency data transmission.

2. Fully transparent to network protocols.

3. Using a dedicated ASIC chip to achieve data line speed forwarding. The programmable ASIC integrates multiple functions on a single chip, which has the advantages of simple design, high reliability, and low power consumption, which can make the device get higher performance and lower cost.

4. Rack-mount devices provide hot-swap functionality for easy maintenance and continuous upgrades.

5. The network management equipment can provide functions such as network diagnosis, upgrade, status report, abnormal situation report and control, and can provide complete operation logs and alarm logs.

6. The device uses a 1+1 power supply design to support an ultra-wide power supply voltage, enabling power protection and automatic switching.

7. Supports an ultra-wide operating temperature range.

8. Supports complete transmission distance (0 to 120 kilometers)

How to choose a fiber transceiver ?

1. Does it support full-duplex and half-duplex?

Some chips currently available in the market can only use a full-duplex environment and cannot support half-duplex. For example, if they receive switches or hubs of other brands, and they use half-duplex mode, they will definitely cause serious problems. Conflicts and lost packets.

2. Is it tested with other fiber transceivers?

Currently, there are more transceivers for optical transceivers on the market. For example, if the compatibility of different brands of transceivers has not been tested beforehand, packet loss, long transmission time, and erratic behavior will occur.

3. Is there a safety device against packet loss?

Some manufacturers in the manufacture of fiber transceiver transceivers, in order to reduce costs, the use of Register (Register) data transmission mode, the biggest drawback of this approach is the transmission instability, packet loss, and the best is to use buffer circuit design, Data loss can be safely avoided.

4, temperature adaptability?

When the fiber transceiver is used, it will generate high heat. When the temperature is too high (cannot be greater than 85°C), does the fiber transceiver work properly? Is a factor that is well worth the customer's consideration!

5. Does it comply with the IEEE802.3u standard?

If the fiber optic transceiver complies with the IEEE802.3 standard, that is, the delaytime is controlled at 46 bits. If it exceeds 46 bits, it means that the distance transmitted by the optical fiber transceiver will be shortened! !

Solid Carbide Drill

Tungsten carbide drill bits are made of tungsten carbide materials, and their own hardness can up to HRC90 degrees. They are mainly used in the field of metal processing to drill holes on workpieces.

Carbide drills can be divided into straight flute drills, twist drills, 3 flutes drills, deep hole drills, step drills, spot drills,etc.

Applications:

Carbide drills can be used in the Automobile industry, like car crankshaft,Car connecting rod,Integral turbine housing,Car engine block,Air conditioning compressor crankshaft,Electric tool cylinder etc.
