What is the maximum transmission distance of 10GBase LR?
10GBase-LR can reach up to 10km over singlemode fiber. There is no minimum distance for LR, either, so it is suitable for short connections over singlemode fiber as well. 10GBase-ER can reach up to 40km over singlemode fiber. Due to the laser power, attenuation is required for links less than 20km long.
What is the distance of SFP LR?
Comparison: SFP-10G-SR vs SFP-10G-LR vs SFP-10G-LRM
| SFP-10G-SR | SFP-10G-LR | |
|---|---|---|
| Rate | 10 Gbps | 10 Gbps |
| Wavelength | 850nm | 1310nm |
| Max. Distance | 300m/400m | 10km |
| Interface | LC duplex | LC duplex |
Is there a minimum distance for single mode fiber?
The data sheet “Cisco SFP Modules for Gigabit Ethernet Applications Data Sheet” says “the minimum cable distance for all SFPs listed (multimode and single-mode fiber) is 6.5 feet (2 m).”
What is the maximum distance of 10GBase SR?
It has a data transmission rate of up to 10.3125 Gbit/s and can be used over multiple cabling options. An example is that when used over 62.5 micrometers OM1 the 10GBASE-SR has a maximum working distance of 33 meters, as opposed to 82 meters when applied over 50 micrometers OM2 cabling.
What is the difference between 10GBASE Sr and 10GBASE SW?
The 10GBASE-SR media type is designed for use over dark fiber, meaning a fiber optic cable that is not in use and that is not connected to any other equipment. The 10GBASE-SW media type is designed to connect to SONET equipment, which is typically used to provide long distance data communications.
What is the maximum distance for 1000Base SX Ethernet type?
Maximum transmission distances for fibre ethernet
| Ethernet Standards (IEEE) | Data Rate | Maximum Distance (IEEE) |
|---|---|---|
| Fast Ethernet (100Base-FX) | 100 Mbps | 2km |
| Fast Ethernet (100Base-SX) | 100 Mbps | 300m |
| Gigabit Ethernet (1000Base-SX) | 1000 Mbps | 550m |
| Gigabit Ethernet (1000Base-SX) | 1000 Mbps | 220m |
What is the difference between SR and LR?
SR stands for Short Reach, and LR stands for Long Reach. SR transceivers are almost always multi-mode, and optimized for high speeds over relatively short distances. Higher end cables and transceivers can support transmissions of several kilometers.
How far can single mode fiber go?
40 km
Single-mode fibre can go as far as 40 km or more without hurting the signal, making it ideal for long-haul applications.
How far can multi mode fiber go?
Applications. The equipment used for communications over multi-mode optical fiber is less expensive than that for single-mode optical fiber. Typical transmission speed and distance limits are 100 Mbit/s for distances up to 2 km (100BASE-FX), 1 Gbit/s up to 1000 m, and 10 Gbit/s up to 550 m.
What is the difference between 10GBASE-Sr and 10GBASE LR?
Based on the above statement, we analyzed and concluded that the main differences between 10GBASE-SR and 10GBASE-LR lie in the type of fiber mode, transmission distance, wavelength and optical power. 10GBASE-LR SFP sets for long distance transmission, and thus single-mode fiber is mainly covered in 10GBASE-LR SFP.
What wavelength is used on a 10GBASE network?
850 nm
The 10GBASE-SR and 10GBASE-SW media types are designed for use over short wavelength (850 nm) multimode fiber (MMF). The design goal of these media types is from 2 meters to 300 meters of fiber distance, depending on the type and quality of the multimode fiber.
