How to Install SFP transceiver?

SFPSFP stands for Small form-factor pluggable, which is a compact, hot-pluggable transceiver used for both telecommunication and data communications applications. It can also be intermixed in combinations of 1000BASE-T1000BASE-SX, 1000BASE-LX/LH, 1000BASE-ZX and 1000BASE-BX10-D/U on a port-by-port basis. Due to its flexbility, it is welcomed by both network component vendors and users and widely applied in Gigabit Ethernet. For that reason, installing SFP transceiver correctly seems very important. This post is going to give a guide to installing SFP transceiver.

Installing a transceiver module without taking correct measures might result in ESD breakdown of the electronic components in the transceiver module or the transceiver module socket. Obviously, if the ESD breakdown, you might not make your network operate smoothly. Thus, it is very crucial to install SFP transceiver correctly. If you don’t have any reference to install SFP transceiver, then the next guide may help deal with that.

Step 1 Attach an ESD-preventive wrist strap to your wrist and to the ESD ground connector or a bare metal surface on your chassis.

Step 2 Remove the SFP transceiver module from its protective packaging. Remember do not remove the optical bore dust plugs until directed to do so later in the procedure.

Step 3 Check the label on the SFP transceiver module body to verify that you have the correct model for your network.

Step 4 Find the send (TX) and receive (RX) markings that identify the top side of the SFP transceiver module.

Step 5 Position the SFP transceiver module in front of the socket opening.

Step 6 Hold it as shown in figure 1, insert the SFP into the socket until you feel the connector latch into place.

Step 7 Press the SFP into the slot firmly with your thumb as shown in figure 2. You must press firmly on both the transceiver face-plate and the actuator button to ensure that the transceiver is properly latched in the socket.

Step 8 To verify that the SFP is seated and latched properly. Grasp the SFP as shown in Figure 3 and try to remove it without releasing the latch.  If the SFP can not be removed, it is installed and seated properly. If the SFP can be removed, reinsert it and press harder with your thumb, repeating if necessary until it is latched securely into the socket.

Installing SFP transceiver correctly is not easy as it looks like. You should keep above guides in mind to avoid any wrong operation which leads paralysis of the entire network system.

Except for SFP transceiver, there are many other types of transceiver that Fiberstore can provide, such as SFP+ transceiver, GBIC transceiver, CWDM/DWDM transceiver and so on.

How to Identify The Refurbished Optical Transceiver Module

Nowadays, there is a variety optical transceivers on the market and some of them may be the refurbished optical transceivers. Driven by the huge economic profit, some unscrupulous manufacturers mislead customers to use the refurbished or inferior optical transceiver modules on their switches, servers, base station equipment or storage devices. What’s worse, they have even faked the famous brand optical transceiver modules. These shoddy refurbished optical transceivers illegally entered the markets may result in heavy losses to us. This article is explaining how to identify the refurbished transceiver modules, and buy a high-quality transceiver module.

Sources & Disadvantages of the Refurbished Optical Transceiver Module

Source

In general, the sources of refurbished transceiver module include the following two ways.

  • Some transceiver modules have been used for certain years, and they will be eliminated due to the update of equipment or damaged due to improper use. The unscrupulous manufacturers recycle these old or damaged transceiver and refurbish them, these refurbished transceiver modules generally have serious impact on the service life.
  • Some unqualified transceiver modules can not pass the on line tests and ready to destroy. These unqualified transceivers are used by the unscrupulous manufactures to fake the high-quality transceivers. However, the parameters of these transceivers are not standard. It will have a great impact on the stability of data transmission, and even have serious damages on the equipment.

Disadvantages

The generally speaking refurbished transceiver modules are referred to the secondhand or unqualified transceiver modules mentioned above. They are bought by some unscrupulous businessmen of low prices and renewed with a number of technical renovation (for example: replacing the shell, replacing the clasp, or replacing the labels, etc). These refurbished transceivers have a lower price than the original one and can easily attract the users. However, many issues have been occurred when using:

  • Pollution on the light path
  • Easy to damage
  • Short using life
  • Low receiving sensitivity
  • Cannot meet the high or low temperature working environment

How to Identify The Refurbished Optical Transceiver Module

Here are three methods to identify the refurbished optical transceiver module:

  • Appearance recognition. Check the appearance of the transceiver modules: new module’s appearance generally has good consistency while the refurbished module is not glossy, and have some wear and scratches in the rim angle. Many refurbished transceivers are replaced with a new shell, in this case, we can see the interface of the modules, if there is dust and not smooth, it is the refurbished modules.
  • Check the ferrule. Pulled out of the dust cap, we can see the ferrule in the bore. In general, the multimode transceiver has plastic ferrules or metal ferrules while the singlemode transceiver has the metal ferrule. A second-hand old module is lack of glossy, and generally rough and with scratch that has a bad consistency. The ferrules of a new quality module is brightness of color and lustre and has a good consistency.
  • Put the modules working under the status of 50-60 °C and see if it is working properly. In generally, a refurbished optical transceiver module can not work well or even disconnect.

Avoiding Refurbished Transceiver Module, A Quality Vendor Is Necessary

No matter there are how many tips or methods on how to identify, the best way to avoid buying refurbished transceiver module is to choose a quality vendor. The reason why many users have bought the refurbished transceivers is the attractive low price of them. As we know, the costs for transceiver modules modules keep adding up over time. In order to save more, a low cost option of the transceiver is the expectation of the users. How and where to find a quality vendor? Fiberstore is your best choice.
