What is a Compatible GLC-SX-MM?

Compatible GLC-SX-MM are an equivalent solution for overpriced original GLC-SX-MM from Cisco, 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 Cisco GLC-SX-MM provide a way to build high-availability connections in high-speed networks in hardware from different manufacturers without having to compromise the arbitrary Cisco price policy of the large world conglomerates. A Cisco compatible GLC-SX-MM offers the same range of functions as an original GLC-SX-MM and differs only in the product label. The technical set-up of Cisco compatible GLC-SX-MM and of original GLC-SX-MM is the same as defined by MSA standards. Only the quality of the installed components can vary. Cisco compatible GLC-SX-MM 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 GLC-SX-MM from Cisco. If you are not yet familiar with compatible Cisco GLC-SX-MM, please let us know. You can request a test sample from gbic-shop.de to try out a compatible Cisco GLC-SX-MM product in your system.

Benefits of a Compatible GLC-SX-MM

Optical GLC-SX-MM 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 GLC-SX-MM.

Low Cost

Optical GLC-SX-MM from Cisco cost a lot more in comparison to compatible GLC-SX-MM. Depending on the model, well-known products are 50% to 1000% more expensive than compatible GLC-SX-MM 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 GLC-SX-MM 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 GLC-SX-MM with high-quality components like the compatible GLC-SX-MM of the BlueOptics brand from gbic-shop.de, which have an above-average lifetime compared to compatible GLC-SX-MM no-name products or conventional compatible GLC-SX-MM brand products, cost only a fraction of the price of original GLC-SX-MM.

Standardized Production

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

Compatible Programming

Compatible GLC-SX-MM must be adapted for the use in its hardware, so that the compatible GLC-SX-MM can be recognized correctly and the hardware does not deny working with the compatible GLC-SX-MM. 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 GLC-SX-MM, who have the appropriate know-how and, if you are concerned, provide a test sample of the desired compatible GLC-SX-MM.

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 GLC-SX-MM 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 gbic-shop.de. In the unexpectedly occurring event of a fault of the compatible GLC-SX-MM you will always receive a corresponding exchange module for your compatible GLC-SX-MM within the guarantee period.

Special products

Some transceiver variants are not available in certain manufacturers' portfolios. Compatible GLC-SX-MM 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 GLC-SX-MM of the brand BlueOptics from gbic-shop.de 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 GLC-SX-MM

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

Poor processing - There are manufacturing companies for compatible GLC-SX-MM, mostly in China, which do not respect the MSA standards during the production process and therefore flood the market with compatible GLC-SX-MM 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 GLC-SX-MM product, you may experience a bad awakening after a few weeks of operation, if not already immediately after commissioning.

Toxic Substances in GLC-SX-MM - If the production of compatible GLC-SX-MM 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 GLC-SX-MM, what is strictly prohibited according to RoHS guidelines.

In order to save costs, in addition to saving on know-how of compatible GLC-SX-MM 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 GLC-SX-MM product. For this reason, caution should be exercised in the case of cheap offers from compatible GLC-SX-MM or vendors that say things they cannot comply with afterwards, what will be revealed firstly when problems occur while using the compatible GLC-SX-MM for a time.

Is a Compatible GLC-SX-MM as good as an Original?

Yes and No. We cannot answer this question in general. Compatible GLC-SX-MM from gbic-shop.de do not have any disadvantages compared to original GLC-SX-MM. Nowadays, there are many compatible GLC-SX-MM that are not even worth the low price they cost. Quickly, the cost of maintenance increases and the savings from buying the compatible GLC-SX-MM from the beginning disappear more than quickly. Even if malfunctions or errors do not necessarily occur immediately when using compatible GLC-SX-MM, inferior compatible GLC-SX-MM 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 GLC-SX-MM product, its longevity and, of course, in the price.

Does a Compatible GLC-SX-MM Void the Warranty of My Cisco Hardware?

No. The use of compatible GLC-SX-MM in Cisco 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 GLC-SX-MM not to be bound to one manufacturer. In so far as you use qualitative compatible GLC-SX-MM, it is also not possible that a defect of the hardware can be caused by a GLC-SX-MM that does not have its own current source.
