What is 10GBASE-LR SFP module?
The Cisco 10GBase-LR SFP+ module offer customers a wide variety of 10 Gigabit Ethernet connectivity options for data center, enterprise wiring closet, and service provider transport applications. The Cisco 10GBase-LR Module supports a link length of 10 kilometers on standard single-mode fiber (SMF, G. 652).
What is the distance limitation 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 SFP 10G ZR?
The Cisco SFP-10G-ZR is a multi-rate 10GBASE-ZR, 10GBASE-ZW, and OTU2/OTU2e module. It supports link lengths of up to about 80 kilometers on standard Single-Mode Fiber (SMF, G.652). This interface is not specified as part of the 10 Gigabit Ethernet standard and is instead built according to Cisco specifications.
Is SFP-10G-SR multimode or singlemode?
SFP-10G-SR is a Cisco multimode 10G transceiver. It supports up to 400m link length when uses 4700Mhz KM OM4 multimode fiber (MMF ). Usually, it was used in a switch SFP slot and support on a wide range of Cisco switches and routers. In the market, the SFP-10G-SR price is various, from $ 10 to $ 800.
Is LR single mode?
LR transceivers are designed for long-range communications, such as wiring buildings together on a large campus or even setting up a Metro Area Network (MAN). They can be either multi-mode or single-mode, and are almost always intended for 100m+ applications.
What does SFP stand for?
small form-factor pluggable
SFP stands for “small form-factor pluggable.” SFP transceivers are compact and hot-pluggable devices that act as an interface between networking equipment (switch, router, network card) and interconnecting cabling (copper or fiber).
Which Ethernet standard is the fastest?
10 Gigabit Ethernet
10 Gigabit Ethernet is the fastest and most recent of the Ethernet standards. IEEE 802.3ae defines a version of Ethernet with a nominal rate of 10Gbits/s that makes it 10 times faster than Gigabit Ethernet. Unlike other Ethernet systems, 10 Gigabit Ethernet is based entirely on the use of optical fiber connections.
What is the maximum distance of 10GBaseSR?
The 10GBaseSR standard specifies a maximum transmission distance of 300 meters, whereas 10GBaseLR specifies a maximum transmission distance of 10,000 meters.
Can 10Gb SFP run at 1Gb?
Most SFP and SFP+ transceivers only run at its rated speed as they are manufactured, thus 10Gb SFP+ optics on 10Gb switch can not auto-negotiate down to 1Gb if the other end is gigabit switch. But when plugging a 1Gb SFP module in the 10G SFP+ port, the 10Gb switch will run at 1Gb.
What is difference between SR and LR SFP?
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. However, the much higher-powered OM3 and OM4 formats can push that into the hundreds of meters for a single cable.
Can 10G SFP+ run at 1g?
Will 10Gb SFP+ running at 1Gb? The answer is definitely “No”. SFP optics do work in SFP+ slots in most cases, but SFP+ optics on 10Gb switch can never work in SFP slots on gigabit switch. The reason is about a power availability thing.
What is single mode and multimode SFP?
The single mode SFP or multimode SFP means the SFP transceivers which work at different types of optical fibers, ie single mode SFP will work with single mode fiber, while multimode SFP will work with multimode fiber.
Which is Cisco sfp-10g-lr-X module?
The Cisco SFP-10G-LR-X is a multirate 10GBASE-LR, 10GBASE-LW, and OTU2/OTU2e module for extended operating temperature range. It supports a link length of 10 kilometers on standard Single-Mode Fiber (SMF, G.652). Cisco SFP-10G-ER-S module (S-Class) The Cisco 10GBASE-ER module supports a link length of up to 40 kilometers on SMF (G.652).
Which is Cisco 10GBASE module does SMF support?
Cisco SFP-10G-ER-S module (S-Class) The Cisco 10GBASE-ER module supports a link length of up to 40 kilometers on SMF (G.652). SFP-10G-ER-S does not support FCoE. Cisco SFP-10G-ER module The Cisco 10GBASE-ER Module supports a link length of up to 40 kilometers on standard Single-Mode Fiber (SMF, G.652).
How big is a Cisco 10Gbase SFP-SR-X?
The Cisco SFP-10G-SR-X is a multirate* 10GBASE-SR, 10GBASE-SW and OTU2/OTU2e module for extended operating temperature range. It supports a link length of 26m on standard Fiber Distributed Data Interface (FDDI)-grade Multimode Fiber (MMF). Using 2000MHz*km MMF (OM3), up to 300m link lengths are possible.
Which is Cisco transceiver module has a 10GBASE link length?
The Cisco SFP-10G-LR-X is a multirate 10GBASE-LR, 10GBASE-LW, and OTU2/OTU2e module for extended operating temperature range. It supports a link length of 10 kilometers on standard Single-Mode Fiber (SMF, G.652). The Cisco SFP-10G-LR10-I supports a link length of 10 kilometers on standard Single-Mode Fiber (SMF, G.652).
