How to Install SFP transceiver Correctly?

SFP (small form factor pluggable) transceiver is now ubiquitous in Gigabit Ethernet networks. It serves as a hot-pluggable I/O devices that being inserted into module sockets to create 1 Gigabit transmission. SFP transceiver is generally used for applications both in telecommunication and data communication, which can be intermixed with 1000BASE-T, 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-ZX and 1000BASE-BX10-D/U on a port-by-port basis. Fail to install SFP transceiver can cause catastrophic damage to the module and network, hence it is better to grasp some knowledge on the right installation procedures.

Precautions for Installing SFP Transceiver

Here are some precautions you should be aware of before delivering installation.

  • Make sure to disconnect all the cables before installing the SFP transceiver, in case any damage that may be caused to cables, connectors and the optical interfaces.
  • Try not to install and remove the SFP transceiver too often since this may shorten its life expectancy.
  • Transceiver modules are rather sensitive to static, it is suggested to use an ESD wrist strap or comparable grounding device during the process of installation and removal.
  • Never remove the dust plug from the SFP transceiver unless you are ready to put it into use. Similarly, the dust plug on the SFP transceiver is used to protect the optical bore and shall not be removed until you attaching patch cable to it.

Additionally, some professional tools are also required to complete the installation, including:

  • Wrist strap or other personal grounding device to prevent ESD occurrence.
  • Antistatic mat or antistatic foam to set the transceiver on.
  • Fiber-optic end-face cleaning tools and inspection equipment.
SFP Transceiver Installation: How to Make it Right?

SFP transceiver primarily have three types of latching devices to secure itself in a port socket: a mylar tab latch, a bale-clasp latch and an actuator button latch. With the bale-clasp latch to be the most widely used one. You should be clear which type of latch your SFP transceiver have before install it. Bear the aforementioned precaution in mind, then perform the following steps to complete installing SFP transceiver.

SFP-transceiver-types-of-latch

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.

Note: Do not remove the optical bore dust plugs until directed to do so later in the procesure.

Step 3. Check the label on the SFP 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.

Note: On some SFP transceivers, the TX and RX marking might be replaced by arrowheads that point from the SFP transceiver connector (transmit direction or TX) and toward the connector (receive direction or RX).

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

Note: different devices may have various SFP module socket configurations, either a latch-up or a latch-down orientation. Ensure that you are installing the SFP transceiver in the correct orientation for your device. Refer to the hardware installation instructions that came with your device for mire details.

Note: For optical SFP transceivers, before you remove the dust plugs and make any optical connections, observe these guidelines:

  • Always keep the protective dust plug on the unplugged fiber-optic cable connectors and the transceiver optical bores until you are ready to make a connection.
  • Always inspect and clean the LC connector end-faces just before you make any connections.
  • Always grasp the LC connector housing to plug or unplug a fiber-optic cable.

 

Step 7. Press the SFP into the slot firmly with your thumb. 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 and try to remove it without releasing the latch. If the SFP can not be removed, it is installed and seated properly. If the it can be removed, reinsert it and press harder with your thumb, repeating if necessary until it is latched securely into the socket.

Step 9. Remove the dust plugs from the LC fiber patch cable and save the dust plugs for future use. Then inspect and clean the patch cable end-face.

Step 10. Remove the dust plugs from the SFP transceiver optical bores. And immediately attach the LC fiber patch cable to the SFP transceiver.

Conclusion

To install a SFP transceiver is a commonplace in data center, yet not as easy as it appears. There are much to consider before you actually perform the action.

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.
