Cisco sfp-10g-sr vs sfp-10g-sr-s: What's the difference?

Cisco's SFP (Small Form-Factor Pluggable) modules come in various flavors to cater to different networking needs. When comparing the Cisco SFP-10G-SR and SFP-10G-SR-S, you're looking at two modules designed for 10 Gigabit Ethernet applications. Here's a breakdown of the key differences:

1. Cisco SFP-10G-SR:

   • Description: This is a standard SFP+ module designed for 10 Gigabit Ethernet applications.

   • Operational Mode: It's meant for short-range and works over multimode fiber (MMF).

   • Distance/Range: Supports distances up to 300m on OM3 MMF.

   • Wavelength: Operates on an 850nm wavelength.

   • Use Cases: Commonly used in data centers, in-building Ethernet connections, and within short-range campus networks.

   • Compatibility: Typically compatible with a broad range of Cisco equipment.

2. Cisco SFP-10G-SR-S:

   • Description: This module is part of Cisco's "S-Class" optics, which are designed to provide a more cost-effective solution for enterprise and data center applications.

   • Operational Mode: Like the SFP-10G-SR, this is a short-range module working over multimode fiber.

   • Distance/Range: Also supports distances up to 300m on OM3 MMF.

   • Wavelength: Operates on an 850nm wavelength.

   • Use Cases: Tailored more towards enterprise-class data center and in-building applications.

   • Compatibility: Might have a more limited compatibility range compared to standard modules. Always good to check the compatibility matrix for your specific Cisco equipment.

   • Cost: Generally, the "S-Class" optics are priced more affordably than their counterparts, providing a cost-effective solution without compromising on quality.

In summary, while both modules seem similar in functionality, the key difference lies in their target markets and price points. The SFP-10G-SR-S is a more budget-friendly option tailored for specific enterprise and data center use cases. Always ensure to check compatibility and support when considering S-Class optics for your networking needs.

What do cisco sfp-10g-sr and sfp-10g-sr-s mean respectively?

What is SFP-10G-SR

SFP-10G-SRis typically used as a part number by Cisco. According to Cisco, it is 10GBASE-SR SFP+ Module supports a link length of 26m on standard Fiber Distributed Data Interface (FDDI)-grade Multimode Fiber (MMF). SFP-10G-SR is a hot-swappable input/output device which allows a 10 Gigabit Ethernet port to link with a fiber optic network. SFP-10G-SR is also used as the replacement model of compatible 10GBase-SR SFP+ Transceiver with the same function and performance supplied by many other 3rd party suppliers and stores.

The Cisco SFP-10G-SRis in full compliance with the 10G BASE-SR standard. This module has a link length of 26m on the most commonly used standard FDDI- grademultimode fiber. FDDI stands for Fiber Distributed Data Interface. It supports a link length of 300m over OM3 cables and a link length of 400m over OM4 cables.

Cisco SFP-10G-SR transceiversare input/output devices that are hot-swappable. They are linked with a fiber optic network via a 10 Gigabit Ethernet port. Since these transceivers are MSA compliant and hot-swappable they can be plugged into any Cisco SFP+ based transceiver port directly. You won’t need to power them from the host network system for this. What this does is to make add-ons, moves, and exchanges fast and efficient.

The Cisco SFP-10G-SR series has 2 other important modules: the Cisco SFP-10G-SR-X Module and the Cisco SFP-10G-SR-S Module. While the Cisco SFP-10G-SR-S module is a part of the Cisco S-classoptics it matches the Cisco SFP-10G-SR module in performance.
 

Knowledge of SFP-10G-SR Compatibility

When you buy SFP-10G-SR transceivers for your switch, you are told to buy “brand” SFP-10G-SR from your network equipment manufacturer in order to keep your system running properly and safely. The “brand” SFP-10G-SR compatibility may never have any issues and the price is therefore very high, usually several hundred dollars. But since the transceivers are all manufactured based on MSA (Multi-source Agreement), which strictly define the operating characteristics of optical transceivers so that system vendors may implement ports in their devices that allow MSA compliant transceivers produced by name brand, as well a third party vendors, to function properly. Transceivers that manufactured by third party vendors usually called compatible transceivers, such as compatible Cisco SFP-10G-SR transceivers. Usually, these compatible transceivers are tested on the corresponding switch before selling, therefore, the compatibility can also be ensured. Cisco SFP-10G-SR matrix can be found here.
 

What is SFP-10G-SR-S

Like as SFP-10G-SR, SFP-10G-SR-Sis typically used as the part number of
Cisco S-Class 10GBASE-SR SFP+ Module. The main difference between SFP-10G-SR and SFP-10G-SR-S is the different features. According to Cisco, S-class optics is an inexpensive option designed for enterprise and data center 10G and 40G applications. The S class is suitable for the below environment: in non-temperature controlled environments, e.g. rugged/ industrial (RGD), Optics plugged on platforms that require extended operating temperature range (EXT), TAA compliance.
 

Will You Buy SFP-10G-SR or SFP-10G-SR-S?

However, with the increasing development of 3rd-party compatible optics market, Cisco S-class optics are as popular as Cisco expected. For instance, you may prefer to buy a Cisco SFP-10G-SRcompatible optics with 18 dollars in Fiberstore rather than about 500 dollars of Cisco SFP-10G-SR-S optics. Because you can enjoy the same functions and performance the Cisco SFP-10G-SR have and just at an incredible price. Of cause, if you are a loyal Cisco user, S-class optics are an ideal choice for you on the most common reaches needed in enterprise and data center applications.
 

What Is the Price of SFP-10G-SR in the Market?

When comparing OEM vs compatible SFP-10G-SR price, you may notice a rather huge gap between them. OEM modules are first-party optics branded by original vendors like Cisco, Juniper, Intel, etc. Usually, equipment vendors subcontract production of these modules to OEM manufacturers, and attach their own logo on the modules, then selling these modules with 10 times and more markup. Compatible 10GBASE-SR modules made with the same spec and MSA standards perform equally as the branded ones, which has become a preferable choice for most users. The compatible SFP-10G-SR price may vary from vendors, but go with FS SFP-10G-SR as the cost-effective & wise choice won't let you down.
