The optic fiber transceiver, also known as an optical converter, is a media conversion equipment for Ethernet transmission that converts short-distance twisted pair electrical impulses to long-distance optical signals.
People perceive optic fiber transceivers differently depending on their perspective. For example, they are separated into single 10M and 100M optic fiber transceivers, 10/100M adaptive optic fiber transceivers, and 1000M optic fiber transceivers based on transmission rate.
To put it bluntly, this means that an electrical signal is converted into an optical signal and then transmitted through an optical fibre to the other end, where the optical signal is converted back into an electrical signal. This is the optic fiber transceiver, which can be divided into single mode and multi-mode optic fiber transceivers.There are different fiber optic transceiver types, you can contact us for more information.
According to daily maintenance, user problems have been summed up in the form of questions and answers to explain one by one, we hope it will assist maintenance personnel in determining the reasons of failure phenomena, find the right point of failure, and find the proper remedy. Details can be found in fiber optic transceiver wiki.
1. What type of cable is utilized to connect the RJ45 port of the transceiver to other devices?
A crossing twisted pair cable connects the transceiver's RJ45 port to a PC network card (DTE data terminal equipment) and a parallel twisted pair cable connects the transceiver's RJ45 port to a HUB or SWITCH (DCE data communication equipment). And we can provide a reasonable 400g optical transceiver price.
2. What is the cause of the optic fiber transceiver TxLink light not turning on?
The improper twisted pair is connected; the contact between the twisted pair crystal head and the equipment is poor, or the twisted pair itself has quality issues; the equipment is not properly linked.
3. What causes the TxLink light to stay on instead of blinking after a typical optical fiber connection?
The failure is usually caused by an excessively long transmission distance or network card compatibility issues (and PC connection).
4. What if all five lights are on or the indicator is normal but the signal cannot be sent?
Turn off the optical fiber transceiver power and reboot a few times to get things back to normal.
5. What is the transceiver's ambient temperature?
Although the optical fiber module includes a built-in automatic gain circuit, it is impacted by ambient temperature. When the temperature reaches a particular range, the optical module's transmitting optical power is affected and lowers.
This degrades the quality of the optical network signal, increasing packet loss rates and potentially disconnecting the optical link (typical fiber module working temperature up to 70 °C).
6. What is the purpose of the link alert on an optical fiber transceiver?
When a fiber drop occurs, the transceiver's link alarm function (linkloss) automatically feeds back to the electrical port (i.e., the electrical port indicator goes out), and if the switch has network management software, it is immediately reflected to the switch's network management software.
1. Is the optical transceiver itself capable of full-duplex and half-duplex communication?
Some chips on the market can only work in full-duplex mode and cannot handle half-duplex. It will undoubtedly create major conflicts and packet loss if it is linked to other brands of switches or hubs that employ half-duplex mode.
2. Have you tried alternative optical fiber transceivers to see if the connection works?
Nowadays, there are an increasing number of optical fiber transceivers on the market. Packet loss, long transmission times, quick and slow transmission, and other issues will occur if the compatibility of several types of transceivers has not been confirmed previously.
3. Is there a security measure in place to prevent packet loss?
Some optical fiber transceiver manufacturers, in order to save money, frequently use the register data transmission mode. The biggest disadvantage of this method is that the transmission is unstable, resulting in packet loss. The best solution is to use a buffer line design, which can safely avoid data packet loss.
4. Adaptability to changing temperatures
When the temperature is too high (not more than 50 °C), the optic fiber transceiver will generate a lot of heat. Whether the optic fiber transceiver is working properly is a very important element for customers to consider!
The optic fiber transceiver is widely used in low-voltage electrical engineering because it is inexpensive, reliable, and simple to use. There are numerous varieties of optical fiber transceivers on the market today.
When purchasing an optic fiber transceiver, look for one with a high visibility and a well-known brand name; don't be tempted by a low price because a low-quality optic fiber transceiver will frequently fail and kill you.
Equipment manufacturers of optical modules will encrypt their devices to varying degrees, also known as compatibility. Modules of a particular brand can only be used with devices of the same brand, and cannot be matched with other brand optical modules. Compatibility manufacturers need to conduct different compatibility adaptations on the optical modules. Whether or not they can perfectly solve compatibility issues is particularly important.
