Cisco sfp-10g-sr-s vs sfp-10g-sr

 
The Cisco SFP-10G-SR and SFP-10G-SR-S are both 10Gbps transceivers that operate over multimode fiber.
Today, let’s make a comparison to help you learn the difference. Please note all the below information is only for reference, you are recommended to buy original transceiver from Cisco or it’s distributor directly. First, we’d better get to know some basic information that helps us classify difference.  

1.SFP-10G-SR:

· It's a part of Cisco's mainstream SFP portfolio which is compatible with the IEEE 802.3ae 10GBASE-SR standard.
· It supports a link length of 26 meters on standard Fiber Distributed Data Interface (FDDI)-grade multimode fiber (MMF). Using 2000MHzkm MMF (OM3), up to 300 meters link lengths are possible. Using 4700MHzkm MMF (OM4), up to 400 meters link lengths are possible.
· It has a bit more flexibility in terms of operating temperature, typically from 0°C to 70°C.

2.SFP-10G-SR-S:

· It's a part of Cisco's S-Class optics, which is a more cost-effective option for lower budgets.
· The S-Class optics are only guaranteed to work with Cisco equipment.
· It supports a link length of 26 meters on standard FDDI-grade MMF. Using 2000MHzkm MMF (OM3), up to 300 meters link lengths are possible. Using 4700MHzkm MMF (OM4), up to 400 meters link lengths are possible.
· The operating temperature range is more limited, typically from 10°C to 60°C.
In summary, the main differences are in the operating temperature ranges and the compatibility of the transceivers with non-Cisco equipment. The SFP-10G-SR-S is a more cost-effective option and is part of Cisco's S-Class optics, while the SFP-10G-SR is part of Cisco's mainstream optics and has a wider operating temperature range.
 
Cisco S-Class Module VS Cisco Non-S-Class Module
Cisco only published four 10G S-class SFP+ modules and two 40G S-class QSFP+ modules. The following table listed Cisco S-class modules. Cisco S-class modules seem to have no differences from the non-S-class modules. However, if you read the specification of these modules and the suggestions from Cisco, you will find the differences.

Data Rate	S-Class Module	Non-S-Class Module	Media
10G	SFP-10G-SR-S	SFP-10G-SR	MMF (duplex)
10G	SFP-10G-LR-S	SFP-10G-LR	SMF (duplex)
10G	SFP-10G-ER-S	SFP-10G-ER	SMF (duplex)
10G	SFP-10G-ZR-S	SFP-10G-ZR	SMF (duplex)
40G	QSFP-40G-SR4-S	QSFP-40G-SR4	MMF (ribbon)
40G	QSFP-40G-LR4-S	QSFP-40G-LR4	SMF (duplex)

 

Protocol

The standard non-S-class Cisco modules like SFP-10G-SR and SFP-10G-LR can support three protocols including Ethernet, OTN (Optical Transport Network) and WAN-PHY (Wide Area Network Physics). However, the S-class modules can only support Ethernet protocol.

Temperature Range

Compared with Cisco C-class modules which can be operating with three different temperature ranges, the Cisco S-class modules can only support the commercial temperature ranges which is 0 to 70°C (32 to 158°F).
Commercial temperature range (COM): 0 to 70°C (32 to 158°F)
Extended temperature range (EXT): -5 to 85°C (23 to 185°F)
Industrial temperature range (IND): -40 to 85°C (-40 to 185°F)

Transmission Distance

Cisco has introduced that the S-class modules are suggested to be used in enterprise network. In addition, the operating temperature range is smaller, thus, S-class module is recommended for shorter transmission distance applications compared with other standard modules.

What is cisco sfp-10g-sr-s?

The Cisco SFP-10G-SR-S is a member of the Cisco S-Class optics, a more budget-friendly line of transceivers. Here are its key features:
1.Standard: Compatible with IEEE 802.3ae 10GBASE-SR standard.
2.Data Rate: Supports 10 Gbps data rate.
3.Fiber Type: Operates over multimode fiber (MMF).
4.Wavelength: Operates at 850nm wavelength.
5.Distance: Supports a link length of 26 meters on standard Fiber Distributed Data Interface (FDDI)-grade multimode fiber (MMF). Using 2000MHzkm MMF (OM3), up to 300 meters link lengths are possible. Using 4700MHzkm MMF (OM4), up to 400 meters link lengths are possible.
6.Operating Temperature: Has an operating temperature range from 10°C to 60°C.
7.Cisco Equipment Only: It is only guaranteed to work with Cisco equipment as opposed to the regular Cisco SFP-10G-SR which may have broader compatibility.
The SFP-10G-SR-S provides the same performance as the Cisco SFP-10G-SR but at a more cost-effective price point, albeit with a more restricted operating temperature and compatibility limited to Cisco devices.
