What is a Compatible TL-SM311LM?

Compatible TL-SM311LM are an equivalent solution for overpriced original TL-SM311LM from TP-Link, which primarily serve as a margin product for the manufacturer, filling the pockets of the company at your expense. As today's standard for the transmission of optical signals in a fiber-optic network, compatible TP-Link TL-SM311LM provide a way to build high-availability connections in high-speed networks in hardware from different manufacturers without having to compromise the arbitrary TP-Link price policy of the large world conglomerates. A TP-Link compatible TL-SM311LM offers the same range of functions as an original TL-SM311LM and differs only in the product label. The technical set-up of TP-Link compatible TL-SM311LM and of original TL-SM311LM is the same as defined by MSA standards. Only the quality of the installed components can vary. TP-Link compatible TL-SM311LM from the brand BlueOptics use only high-quality brand lasers (such as Avago or Lumentum) and high-quality ICs (such as Maxim Integrated or Netlogic) and therefore have the same quality or even a better quality as the original TL-SM311LM from TP-Link. If you are not yet familiar with compatible TP-Link TL-SM311LM, please let us know. You can request a test sample from to try out a compatible TP-Link TL-SM311LM product in your system.

Benefits of a Compatible TL-SM311LM

Optical TL-SM311LM are special industrial products which, as a compatible variant, should only be obtained from a specialist in order to benefit from the following advantages of compatible TL-SM311LM.

Low Cost

Optical TL-SM311LM from TP-Link cost a lot more in comparison to compatible TL-SM311LM. Depending on the model, well-known products are 50% to 1000% more expensive than compatible TL-SM311LM from third-party suppliers. Depending on the number of ports required this can quickly increase the cost of a fiber-based network. In this case, however, it is important not to purchase any compatible TL-SM311LM junk products where the quality suffers during the production or already during the product design process which leads to link errors or complete failures of a connection after a short period of use. But even long-life compatible TL-SM311LM with high-quality components like the compatible TL-SM311LM of the BlueOptics brand from, which have an above-average lifetime compared to compatible TL-SM311LM no-name products or conventional compatible TL-SM311LM brand products, cost only a fraction of the price of original TL-SM311LM.

Standardized Production

By setting standards and norms for pluggable TL-SM311LM in the internationally appointed Multi-Source Agreement (MSA), compatible TL-SM311LM can be designed to meet the exact specifications for an exact fit of the compatible TL-SM311LM, the correct design of the compatible TL-SM311LM and the exact operation of the compatible TL-SM311LM. Depending on the choice of the internal installed components, compatible TL-SM311LM can be just as qualitative as the original TL-SM311LM. There is therefore no risk of incompatibilities when using compatible TL-SM311LM insofar the MSA standards are applied. In addition, compatible TL-SM311LM meet all industrial standards, norms and communications regulations. Compatible TL-SM311LM of the brand BlueOptics from meet all specifications and reach or even exceed all standards.

Compatible Programming

Compatible TL-SM311LM must be adapted for the use in its hardware, so that the compatible TL-SM311LM can be recognized correctly and the hardware does not deny working with the compatible TL-SM311LM. Incorrect programming can lead to functional restrictions as well as a complete lack of function. It is therefore advisable to look for a trusted supplier for the acquisition of compatible TL-SM311LM, who have the appropriate know-how and, if you are concerned, provide a test sample of the desired compatible TL-SM311LM.

Long Warranty Periods

Some manufacturers do offer limited warranty periods on original products, usually about one year. Others offer life-long warranty periods. However, this lifetime refers to the time while the product is officially offered. If this is terminated as End of Life (EOL) product, the warranty expires. What this says about the real lifetime of a product is left to your imagination. Compatible TL-SM311LM of the brand BlueOptics, on the other hand, have a warranty period of 5 years and an average life expectancy of 10 years with continuous individual support from In the unexpectedly occurring event of a fault of the compatible TL-SM311LM you will always receive a corresponding exchange module for your compatible TL-SM311LM within the guarantee period.

Special products

Some transceiver variants are not available in certain manufacturers' portfolios. Compatible TL-SM311LM can be adapted in such a way that even module types with other specifications which are not officially supported by the manufacturer can be used to enable special applications or higher ranges. Compatible TL-SM311LM of the brand BlueOptics from are 100% compatible, are MSA and RoHS compliant, have an above average lifetime and are available for more than 165 different vendors.

Disadvantages of a Compatible TL-SM311LM

Compatible TL-SM311LM from offer no disadvantages in terms of quality, processing and operation compared to original TL-SM311LM. However, if you only pay attention to the price when buying compatible TL-SM311LM, you can be surprised badly and cause big problems.

Poor processing - There are manufacturing companies for compatible TL-SM311LM, mostly in China, which do not respect the MSA standards during the production process and therefore flood the market with compatible TL-SM311LM products that lack precision, show incompatibilities, cause hardware damage or are simply sloppily manufactured and thus endangering security. Since you cannot notice this by just looking at the compatible TL-SM311LM product, you may experience a bad awakening after a few weeks of operation, if not already immediately after commissioning.

Toxic Substances in TL-SM311LM - If the production of compatible TL-SM311LM is not observed to comply with valid industrial and environmental standards, this will lead to a risk to life and limb for you and your employees. Lead and other toxins are used in unclean production processes for compatible TL-SM311LM, what is strictly prohibited according to RoHS guidelines.

In order to save costs, in addition to saving on know-how of compatible TL-SM311LM and endangering our environment, saving on certifications such as ISO9001 or non-compliance with work laws and work standards are other aspects on how to minimize the total price of a compatible TL-SM311LM product. For this reason, caution should be exercised in the case of cheap offers from compatible TL-SM311LM or vendors that say things they cannot comply with afterwards, what will be revealed firstly when problems occur while using the compatible TL-SM311LM for a time.

Is a Compatible TL-SM311LM as good as an Original?

Yes and No. We cannot answer this question in general. Compatible TL-SM311LM from do not have any disadvantages compared to original TL-SM311LM. Nowadays, there are many compatible TL-SM311LM that are not even worth the low price they cost. Quickly, the cost of maintenance increases and the savings from buying the compatible TL-SM311LM from the beginning disappear more than quickly. Even if malfunctions or errors do not necessarily occur immediately when using compatible TL-SM311LM, inferior compatible TL-SM311LM can already lead to this in a short time. Reasons for this are poor processing, failure to comply with standards and norms and, above all, the use of lasers and ICs from Asian manufacturers, in the worst case from China, which have not been able, as of now, to match the quality of traditional companies for transmission technology from the US by far. As with any electronic component, this is naturally reflected in the quality of the compatible TL-SM311LM product, its longevity and, of course, in the price.

Does a Compatible TL-SM311LM Void the Warranty of My TP-Link Hardware?

No. The use of compatible TL-SM311LM in TP-Link hardware does not void or compromise the warranty of the hardware. Since networks are becoming increasingly heterogeneous and many products from different manufacturers are used, it is only natural for TL-SM311LM not to be bound to one manufacturer. In so far as you use qualitative compatible TL-SM311LM, it is also not possible that a defect of the hardware can be caused by a TL-SM311LM that does not have its own current source.
