The SFP-10G optical module is a small form-factor fiber module used for transmitting data at 10 gigabits per second (Gbps). It is a hot-swappable module commonly used to connect network devices such as switches, routers, server network cards, etc., enabling high-speed data transmission.

The SFP-10G optical module comes in various types, including SFP-10G-SR and SFP-10G-LR. These types represent different transmission distances and fiber types.

SFP-10G-SR is a type of optical module. Main Parameters:

        Rate: 10G

        Package Type: SFP+

        Transmission Wavelength: 850nm

        Transmission Distance: 300M

        Transmission Medium: Multimode

        Fiber Interface: LC

Explaining what SFP-10G-SR and SFP-10G-LR represent:

The 10G SFP+ 850nm 300M LC DDM module adheres to the 10GBase-SR standard, where "SR" stands for "short range". It operates on short-wavelength (850nm) multimode fiber (MMF) with a transmission distance of 300m. To support 300m transmission, optimized 50μm core OM3 fibers are required. This standard offers advantages such as low cost, compact size, and distance transmission. The SFP-10G-SR optical module complies with this specification.

What is SFP-10G-LR?

Main Parameters:

        Rate: 10G

        Package Type: SFP+

        Transmission Wavelength: 1310nm

        Transmission Distance: 10M

        Transmission Medium: Single mode

        Fiber Interface: LC

Explaining what SFP-10G-SR and SFP-10G-LR represent:

The 10GBase-LR standard uses "LR" to denote "long range". It operates on a wavelength of 1310nm single-mode fiber (SMF) with a transmission distance of 10km. The SFP-10G-LR optical module complies with this specification, offering compact size, low power consumption, and long-distance transmission capabilities.

When selecting optical modules, compatibility and cost must be considered. Many third-party manufacturers produce compatible Cisco SFP-10G-SR/LR optical modules, but not all have good compatibility. Therefore, it is essential to ensure compatibility between the optical module and the switch when purchasing. Additionally, cost is a significant consideration. Many users choose third-party compatible fiber optic modules to save costs while ensuring quality. Walsun's SFP-10G-SR and SFP-10G-LR compatible optical modules offer high cost-effectiveness, full compatibility, and are recommended!
