Compatible Lenovo B4R2 BlueLAN passive 200GBASE-CR4 QSFP56 to 2x100GBASE-CR2 QSFP56 Direct Attach Breakout Cable, 2 Meter, AWG26

What is a Compatible B4R2?

Compatible B4R2 are an equivalent solution for overpriced original B4R2 from Lenovo, 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 electrical signals in a network, for example in a data center, compatible Lenovo B4R2 Direct Attach Cables (DAC) provide a way to build high-availability connections in high-speed networks on short distances without having to compromise the arbitrary Lenovo price policy of the large world conglomerates. A Lenovo compatible B4R2 offers the same range of functions as an original B4R2 and differs only in the product label. The technical set-up of Lenovo compatible B4R2 and of original B4R2 is the same as defined by MSA standards. Only the quality of the installed components can vary. Lenovo compatible B4R2 from the brand BlueLAN use only high-quality brand cables (such as Belden, Molex or TE Connectivity) and high-quality ICs (such as Maxim Integrated or Netlogic) and therefore have the same quality or even a better quality as the original B4R2 from Lenovo. If you are not yet familiar with compatible Lenovo B4R2, please let us know. You can request a test sample from gbic-shop.de to try out a compatible Lenovo B4R2 product in your system.

Benefits of a Compatible B4R2

B4R2 DACs 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 B4R2.

Low Cost

B4R2 DACs from Lenovo cost a lot more in comparison to compatible B4R2. Depending on the model, well-known products are 50% to 1000% more expensive than compatible B4R2 from third-party suppliers. Depending on the number of ports required this can quickly increase the cost of a network. In this case, however, it is important not to purchase any compatible B4R2 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 B4R2 with high-quality components like the compatible B4R2 of the BlueLAN brand from gbic-shop.de, which have an above-average lifetime compared to compatible B4R2 no-name products or conventional compatible B4R2 brand products, cost only a fraction of the price of original B4R2.

Standardized Production

By setting standards and norms for B4R2 DACs in the internationally appointed Multi-Source Agreement (MSA), compatible B4R2 can be designed to meet the exact specifications for an exact fit of the compatible B4R2, the correct design of the compatible B4R2 and the exact operation of the compatible B4R2. Depending on the choice of the internal installed components, compatible B4R2 can be just as qualitative as the original B4R2. There is therefore no risk of incompatibilities when using compatible B4R2 insofar the MSA standards are applied. In addition, compatible B4R2 meet all industrial standards, norms and communications regulations. Compatible B4R2 of the brand BlueLAN from gbic-shop.de meet all specifications and reach or even exceed all standards.

Compatible Programming

Compatible B4R2 must be adapted for the use in its hardware, so that the compatible B4R2 can be recognized correctly and the hardware does not deny working with the compatible B4R2. 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 B4R2, who have the appropriate know-how and, if you are concerned, provide a test sample of the desired compatible B4R2.

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 B4R2 of the brand BlueLAN, 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 B4R2 you will always receive a corresponding exchange cable for your compatible B4R2 within the guarantee period.

Special products

Some cable variants are not available in certain manufacturers' portfolios. Compatible B4R2 can be adapted in such a way that even cable types with other specifications which are not officially supported by the manufacturer can be used to enable special applications or higher ranges. Compatible B4R2 of the brand BlueLAN 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 B4R2

Compatible B4R2 from gbic-shop.de offer no disadvantages in terms of quality, processing and operation compared to original B4R2. However, if you only pay attention to the price when buying compatible B4R2, you can be surprised badly and cause big problems.

Poor processing - There are manufacturing companies for compatible B4R2, mostly in China, which do not respect the MSA standards during the production process and therefore flood the market with compatible B4R2 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 B4R2 product, you may experience a bad awakening after a few weeks of operation, if not already immediately after commissioning.

Toxic Substances in B4R2 - If the production of compatible B4R2 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 B4R2, what is strictly prohibited according to RoHS guidelines.

In order to save costs, in addition to saving on know-how of compatible B4R2 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 B4R2 product. For this reason, caution should be exercised in the case of cheap offers from compatible B4R2 or vendors that say things they cannot comply with afterwards, what will be revealed firstly when problems occur while using the compatible B4R2 for a time.

Is a Compatible B4R2 as good as an Original?

Yes and No. We cannot answer this question in general. Compatible B4R2 from gbic-shop.de do not have any disadvantages compared to original B4R2. Nowadays, there are many compatible B4R2 that are not even worth the low price they cost. Quickly, the cost of maintenance increases and the savings from buying the compatible B4R2 from the beginning disappear more than quickly. Even if malfunctions or errors do not necessarily occur immediately when using compatible B4R2, inferior compatible B4R2 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 cables 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 B4R2 product, its longevity and, of course, in the price.

Does a Compatible B4R2 Void the Warranty of My Lenovo Hardware?

No. The use of compatible B4R2 in Lenovo 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 B4R2 not to be bound to one manufacturer. In so far as you use qualitative compatible B4R2, it is also not possible that a defect of the hardware can be caused by a B4R2 that does not have its own current source.

Each BlueLAN BO25K859S2D QSFP56 to 2xQSFP56 DAC Direct Attach Cable is covered by a 5-year functional warranty from CBO.
