The "SFP-10G-SR" and "SFP-10G-SR-S" are two different types of SFP+ transceivers made by Cisco.
1.SFP-10G-SR: This is a standard SFP+ transceiver that operates over multimode fiber with a wavelength of 850 nm. It supports data rates up to 10 Gbps and is designed for short-range applications, typically up to 300 meters.
2.SFP-10G-SR-S: This is part of Cisco's S-Class optics, which are a more cost-effective option compared to the standard transceivers. The "SFP-10G-SR-S" has similar specifications to the "SFP-10G-SR" (850 nm wavelength, 10 Gbps data rate, multimode fiber), but it may have a reduced feature set and is typically recommended for use within the same data center or campus.
The key difference between the two is that the "SFP-10G-SR-S" is part of Cisco's S-Class optics, which are designed to be a more cost-effective solution for short-range data center applications. It may not have all the features of the standard "SFP-10G-SR" transceiver and is not recommended for use in all the same applications.
 
 

What do sfp-10g-sr and sfp-10g-sr-s respectively represent?

 
 

What is sfp-10g-sr?

The SFP-10G-SR is a 10GBASE-SR SP+ module, which can reach up to 300 meters matched with OM3 Multimode Fiber (MMF), known as the lowest-cost, lowest-power modules implemented with a VCSEL.
 
The "SFP-10G-SR" is a type of SFP+ transceiver.
1.SFP: It stands for Small Form-factor Pluggable. It is a compact, hot-pluggable optical module transceiver used for both telecommunication and data communications applications.
2.10G: It represents the data rate, which is 10 Gbps (Gigabits per second).
3.SR: It stands for Short Range. This indicates that this transceiver is designed for short-range applications.
So, the "SFP-10G-SR" is an SFP+ transceiver that operates over multimode fiber with a wavelength of 850 nm, and supports data rates up to 10 Gbps. It is designed for short-range applications, typically up to 300 meters.
 
 
 
 

What is sfp-10g-sr-s?

Like as SFP-10G-SR, SFP-10G-SR-S is 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.
 
"SFP-10G-SR-S" is a Cisco S-class transceiver module.
1.SFP: Stands for Small Form-factor Pluggable. It is a compact, hot-pluggable optical module transceiver used for both telecommunication and data communications applications.
2.10G: It represents the data rate, which is 10 Gbps (Gigabits per second).
3.SR: Stands for Short Range. This indicates that this transceiver is designed for short-range applications.
4.S: The "S" in "SR-S" indicates that this is an "S-Class" or "Standard" Cisco transceiver, which is a more cost-effective solution compared to the enterprise-class or "non-S" version.
The "SFP-10G-SR-S" is a Cisco S-class transceiver that operates over multimode fiber with a wavelength of 850 nm and supports data rates up to 10 Gbps. It is designed for short-range applications, typically up to 300 meters. The "S" class or "Standard" version offers the same functionality as the regular "SFP-10G-SR" but is generally more cost-effective and may have a shorter warranty period.
