Question about WS-X4612-SFP-E: 12-Ports SFP

Qustion: I have one part no. from Cisco i.e. Cisco module WS-X4612-SFP-E which shows "E-Series 12-Port GE (SFP)"

can anyone pls advice does this comes as a Line card slot to put SFP or this part no includes Line Card slot + SPFs,

Reason to ask is either I have to buy the separate SFPs or does this Line card itself comes with SFP.

The solution:

Cisco line cards NEVER come WITH SFPs - they are a separate item.

You will have to chase up the supply and price from a IT supplier, confirming the presence or absence of the SFP for that specific quote to meet you specific needs.

As the SFP are separately available they won't be included unless the actual sale indicated they are added in to your specific sale. The price you quoted doesn't tell me what is included. That price could have come for any of over a thousand different suppliers.

IT isn't easy and that is why this site is such a great source of information, but at the end of the day each of us has to do the hard work of identifying the actual hardware and the accessories with a price that actually includes each item we require in it. Sometimes I don't even know enough about it to know what I want. This is the normal work of IT experts. Identify what we don't know and learn about it as fast as possible.

I use the term mini-GBIC and it is the same as SFP. This makes it harder to communicate but can I encourage you to identify with the supplier what they are actually quoting on and what is missing. If the supplier is difficult to understand I stop and try to clarify the words they use to describe an item and what that means. It sometimes takes me hours to finally sort out the terminology and specific way a technology is supplied only to find out another supplier does it differently. Yes, I spend the time learning and adjusting so I can make great purchases without mistakes.

Another question is what sort of SFP's do you need? What speed? What sort of physical connections to the fibre are needed? What type of fibre is it and will this SFP match it.
There is 50 micron and 62.5 micron fibre, also referred to as om1 om2 and om3

Then there's the question of the other end of the fibre run. I have found the hard way that in some circumstances you need a matching SFP at the other end for the link to run.

Sigh, the normal work of IT specialists is being game and confident enough to wade into any previously unknown field and become comfortable and fluent in all aspects of the technology as quickly as possible.

If you want to post a copy of the quote without naming the supplier I'll be happy to have a look at it.

Where to buy Cisco WS-X6724-SFP

Where to buy Cisco WS-X6724-SFP, more lower price and original product?
WS-X6724-SFP : Fabric-Enabled 24-Port SFP-Based Gigabit Ethernet Module. The list price is US$15,000.00.
Distributors, like Ingram Micro, Comstor, Tech Data, Redington etc, different countries different distributors, also different price related to your region, partner level and project level, normally around 30%~60% off GPL;

The price comparison:
1 http://www.hardware.com/products/cisco/WS-X6724-SFP%3d 6342.34 USD, 32% off, more professional but price too too expensive;

2 http://www.servermonkey.com/cisco-ws-x6724-sfp.html 4999.99 USDas can see from their description, also the list price is not correct. But they are the shop of US, if you are located in US, maybe you can try, otherwise better find a professional networking supplier.

3 http://www.amazon.com/Cisco-WS-X6724-SFP-Catalyst-24-Port-Ethernet/dp/B00018BCTE3849 USD, good price but frankly speaking Amazon is not professional in Cisco products at all, and mary products maybe not the original ones.

4 according to our research on WS-X6724-SFP Price, best price is from, http://www.3anetwork.com/cisco-ws-x6724-sfp-price_p1291.html, 5248 USD, 65% off, but they are based in Hong Kong, so may take 3 days to reach your country.

The Cisco Catalyst 4500E Series extends control to the network edge with intelligent network services, including sophisticated quality of service (QoS), predictable performance, advanced security, comprehensive management, and integrated resiliency. Scalability of these intelligent network services is made possible with dedicated, specialized resources known as ternary content-addressable memory (TCAM). Ample TCAM resources (up to 384,000 entries) enable "high feature capacity", which provides wire-speed routing and switching performance independent of provisioning of services such as QoS and security.

Cisco SFP-10G-LR VS SFP-10G-SR, what is the difference

Question: what is the difference between the SFP-10G-LR and SFP-10G-SR

 

Answer: The Cisco 10GBASE SFP+ modules (Figure 1) offer customers a wide variety of 10 Gigabit Ethernet connectivity options for data center, enterprise wiring closet, and service provider transport applications.

 

Cisco SFP-10G-LR

The Cisco 10GBASE-LR Module supports a link length of 10 kilometers on standard single-mode fiber (SMF, G.652). 10GBASE-LR 1310nm SMF.

Transmit Power -8.2 to 0.5. Receive Power (dBm): -14.4 to 0.5. Transmit and Receive Wavelength: 1260 to 1355. Bail Latch Color: Blue.

 

Cisco SFP-10G-SR

The Cisco 10GBASE-SR Module supports a link length of 26m on standard Fiber Distributed Data Interface (FDDI)-grade multimode fiber (MMF). Using 2000MHz*km MMF (OM3), up to 300m link lengths are possible. Using 4700MHz*km MMF (OM4), up to 400m link lengths are possible.

Transmit Power -7.3 to 1.2**. Receive Power (dBm): -9.9 to 1.0. Transmit and Receive Wavelength: 840 to 860. Bail Latch Color: Beige.
