How to select right Cisco SFP-10G-SR transceiver ?

Today’s data centers have to better conform to virtualized workloads as well as the ongoing enterprise transition toward hybrid clouds, As you know, most of companies always make use of big data technology in order to find timely information and make right judgement. Transceiver module is one of the most critical designs in telecommunication field, which is related to the promotion of big data in data centers, helping enterprises get data in real-time. This article will focus on How to select right Cisco SFP-10G-SR transceiver .

Cisco SFP-10G-SR transceiver is hot-swappable input/output device which allows a 10 Gigabit Ethernet port to link with a fiber optic network. The Cisco SFP-10G-SR transceiver can be plugged directly into any Cisco SFP+ based transceiver port without the need to power down the host network system due to hot-swappable and MSA compliant .

What's the main difference between Cisco SFP-10G-SR and SFP-10G-LR transceivers?

SR stands for Short Reach, and LR stands for Long Reach. SR transceivers are almost always multi-mode and optimized for high speeds over relatively short distances. However, the  higher-powered OM3 and OM4 formats can push that into the hundreds of meters for a single cable. LR transceivers are designed for long-range communications, such as wiring buildings together on a large campus or even setting up a Metro Area Network (MAN). They can be either multi-mode or single-mode, and are almost always intended for 100m+ applications. Higher end cables and transceivers can support transmissions of several kilometers.

How different between the "SFP-10G-SR-S" and "SFP-10G-SR" ?

S-class optics are available only in the most common reaches needed in enterprise and data center applications. S-class is Ethernet only, no OTN or Wide Area Network Physics (WAN-PHY) standards . In addition, it is no TAA compliance for S-class. Moreover, S-class and non-S-class optics are with different temperature ranges. Thus, if you are an enterprise or datacenter environment that doesn’t need any special long distance, temperature tolerances, or other special features, S-Class optics are cheaper and should be just fine for you.

What factors should be considered while people buy Cisco 10G SFP+ ?

Aside from IEEE standard and transmission distance, compatibility and costs should be considered to make sure to select the right 10G SFP+ modules. 

As you know, Cisco has a variety of switches and 10G SFP+ transceiver modules, even if you had originally purchased a brand new module, not all SFP+ modules could perfect well on every Cisco switches SFP+ port ,because different Cisco switches have distinct requirement for codes and hardware .Therefore,you must make sure whether the SFP+ is compatible with your switch or not before selecting the SFP+ msodule for your Cisco switch.

SFP+ module is just the tip of whole fiber optic network iceberg , Cisco-brand transceivers will cost you a lot in any case, prices of third-party optical transceivers are much lower than the those original brands . Thus, chosing cost-effective modules are necessary, there are a lot of third party modules compatible with Cisco switches at lower price with superior quality.

Summary

Where to purchase Cisco 10G SFP+ Modules? you could directly purchase the modules from Cisco original brand if you do not take cost into account. However, third-party transceivers are ideal option for your transceivers solutions. If you plan to buy the third-party transceivers for a cost-effective solution, you’d better choose a vendor with good quality and compatibility. Utoptical offers a full range of Cisco compatible 10G SFP+ modules,which are 100% tested in original brand switches to make sure the compatibility and quality.
