OEM and 3rd Party Brocade 40G-QSFP-ESR4

Yes, transceivers are small, but they're an important component in your network. What's more? Since so many of them are ordered in bulk, the savings available through MULTI-LINK can add-up quickly, and the 40G-QSFP-ESR4 is no exception.

That said, savings don't add-up to anything without guaranteed compatibility! Customers are rightly concerned with the seemingly endless supply of counterfeit transceivers coming from overseas, some of which can damage your equipment or "freeze" individual components within your network.

MULTI-LINK (MLCP) has never and will never pursue the "quick buck" by working with an unknown transceiver supplier, and that principle has helped pave the way for transitioning so many of our customers from OEM or “Manufacturer-labeled” to 3rd Party 40G-QSFP-ESR4 transceivers. The original equipment manufacturer might try to tell you otherwise, but we can guarantee compatibility with 3rd Party transceivers (i.e. properly coded EEPROMs). In fact, we can either guarantee that an individual 3rd Party 40G-QSFP-ESR4 option will work in the OEM equipment in question, or we simply won't sell it, period!

Want more assurance? We'll send samples for your test & evaluation with no obligation whatsoever.

To be sure, if you prefer a manufacturer-labeled new or refurbished 40G-QSFP-ESR4, we are happy to assist, and we can typically do so at a considerable savings. However, we have an ever-expanding international base of happy 3rd Party GBIC and SFP customers, all saving significantly over even the largest factory discounts. We'd welcome the opportunity to discuss and explore this option with your company. Perhaps your 40G-QSFP-ESR4 interest provides an opening for such a discussion.

MULTI-LINK offers a Lifetime warranty on most transceivers we provide, regardless of new or used, and regardless of manufacturer-labeled or 3rd Party. That's how confident we are in all the transceivers we provide!

Optimized, Certified Optical Transceivers for Extending Data Center Networks

Today's enterprise data centers and networking environments are undergoing an infrastructure transformation, requiring higher speeds, greater scalability, and higher levels of performance and reliability to better meet the demands of business. As speed and performance needs increase, optical transceivers have become an integral part of overall system design. However, optical transceiver design margins and parameters vary widely, and can be the difference between an optimized, highly reliable fabric and incompatibility issues that drive up support costs.

The Brocade® 40 Gbps eSR4 QSFP+ Optical Transceiver, part of the Brocade family of optical transceivers, is optimized to fully leverage Brocade 40 Gigabit Ethernet (GbE) switches and routers. Together, these optical transceivers provide state-of-the-art performance, helping IT organizations achieve new levels of infrastructure consolidation while expanding the capabilities of their applications and services.
