OPTCORE OSP10G-8503DCR 10G SFP+ SR Transceiver Overview

Today we have a review of the OPTCORE OSP10G-8503DCR 10G SFP+ SR transceiver. This is one of the cheapest 850nm SFP+ modules we have seen with wide compatibility. To be frank, we don’t have quite much feedbacks from OPTCORE customers, but this is our first try to do so. We didn’t know what to expect. Generally speaking, the OSP10G-8503DCR 10G SFP+ SR offers more than we expected. This 10G SFP+ SR transceiver may be one of the best cost-effective choices when you looking for a lower-cost third-party 10G optical transceiver with good compatibility.

OPTCORE OSP10G-8503DCR 10G SFP+ SR Transceiver Overview

Taking a look at the OSP10G-8503DCR spec we can find it is a multimode 850nm SFP+ transceiver that supports 10GBASE-SR/SW short-reach application.

OPTCORE’s model is to provide low-cost optics and also offer many coding options for specific switches. For example, to have a module coded for Cisco, Brocade, Extreme, or other companies, you can filter and specified on the product page. OPTCORE guarantees that it works if ordered correctly coded transceiver.

This 10G SFP+ SR module features a DOM function to support the real-time monitor. DOM is a feature that allows users to monitor transceiver module parameters such as temperature, supply voltage, laser bias current, and transmit and receive optical power in real-time. By measuring these parameters, it can help identify the location of fiber optic link failures, simplify maintenance, and improve system reliability, thus helping network administrators to check and ensure the proper operation of the modules.

Warranty

We will note here that these 10G SFP+ SR transceivers have a 3-year warranty. For most of our users, if the transceiver falls within this price range, if it fails within 3 years, the transceiver optics will be replaced by a different model from a different supplier.

Final Words

The dramatic increase in network traffic has made 10Gbps applications very popular and common, and the technology is mature enough that the differences between modules are minimal. Users do not need to worry about the performance and compatibility of these third-party optical transceivers. For SMB users or users in-home/office lab environments with limited budgets, these SFP+ modules are perfectly suited to meet the needs and, crucially, provide the most cost-effective alternative solution. In fact, however, there are many IT users who are required to use certified modules in their switches to comply with their IT policies. While these modules may not void your warranty, if there is a problem with the switch or network, the switch vendor will often point to the third-party module, whether it is the culprit or not.

So, the ultimate decision is still up to the user. If you use an original optical transceiver, then you’ll pay a premium, but relatively hassle-free service. If you use a third-party optical transceiver, you have the opportunity to significantly reduce the cost of your network equipment investment, sometimes by as much as 80%, which can ultimately help you upgrade and deploy higher-speed network facilities.

Overall, the OPTCORE OSP10G-8503DCR 10G SFP+ SR offers a wide range of compatibility options and is sold at a retail price of $13, which is very reasonably priced compared to many other vendors. Based on the very low price, it is worthwhile for network users to try this optical transceiver, it should not disappoint you.
