10 Gigabit Transceivers And Cables

In computer networks, 10 Gigabit Ethernet refers to various technologies for transmitting Ethernet frames at a rate of 10 gigabits per second (10×109 or 10 billion bits per second), first defined by the IEEE 802.3ae-2002 standard. 10-Gigabit Connections For 10-Gigabit Ethernet cabling the fiber options are very similar. The transceivers are somewhat different, as is some nomenclature. New possibilities have evolved for copper connections.

Transceivers
Standards bodies initially offered several options for the 10-Gigabit transceiver. 10G transceivers series include QSFP+ Transceiver, XFP Transceiver, SFP+ Transceiver, XENPAK module Transceiver and X2 Transceiver. The one that ultimately evolved as most popular in commercial data center usage was the SFP+ transceiver. The Cisco 10GBASE SFP+ modules offer customers a wide variety of 10 Gigabit Ethernet connectivity options for data center, enterprise wiring closet, and service provider transport applications.

Cisco SFP-10G-SR
The Cisco 10GBASE-SR Module supports a link length of 26m on standard Fiber Distributed Data Interface (FDDI)-grade multimode fiber (MMF). It is 10GBase SR compliant and work at 850nm, this transceiver is in standards SFP+ package to plug into the ports or slots on Cisco equipment, optical interface is duplex LC connector. Using 2000MHz*km MMF (OM3), up to 300m link lengths are possible. Using 4700MHz*km MMF (OM4), up to 400m link lengths are possible.

Cisco SFP-10G-SR-X
The Cisco SFP-10G-SR-X is a 10GBASE-SR 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. Using 4700MHz*km MMF (OM4), up to 400m link lengths are possible.

Cisco SFP-10G-LRM
The Cisco 10GBASE-LRM Module supports link lengths of 220m on standard Fiber Distributed Data Interface (FDDI) grade multimode fiber (MMF). To ensure that specifications are met over FDDI-grade, OM1 and OM2 fibers, the transmitter should be coupled through a mode conditioning patch cord. No mode conditioning patch cord is required for applications over OM3 or OM4. The Cisco 10GBASE-LRM Module also supports link lengths of 300m on standard single-mode fiber (SMF, G.652).

Cisco FET-10G
The Cisco FET-10G Fabric Extender Transceiver support link lengths up to 100m on laser-optimized OM3 or OM4 multimode fiber. It is supported on fabric links only from a Nexus 2000 to a Cisco parent switch.

Cisco SFP-10G-LR
The Cisco 10GBASE-LR Module is single mode, supports a link length of 10 kilometers on standard single-mode fiber (SMF, G.652).

Cisco SFP-10G-LR-X
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
The Cisco 10GBASE-ER Module supports a link length of up to 40 kilometers on standard single-mode fiber (SMF, G.652).

Cisco SFP-10G-ZR
The Cisco SFP-10G-ZR is a multirate 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.

10GbE supports both copper and fiber cabling. However, due to its higher bandwidth requirements, higher-grade copper cables are required: category 6A or Class F/Cat 7 Ethernet cable price for links up to 100m. Unlike previous Ethernet standards, 10 gigabit Ethernet defines only full duplex point-to-point links which are generally connected by network switches. Half duplex operation and hubs do not exist in 10GbE.

Serval Cisco Fiber Optic Transceivers

Within the optical communication marketplace, there are several sorts of fiber optic transceivers which are SFP, GBIC, X2 and so on. Cisco is really a brand that has great overall performance on fiber optic products.

As among the fundamental fiber optic transceivers, Cisco SFP is generally utilized in many locations. The inexpensive price and the higher performance, would be the benefits of Cisco SFP. As all recognized, the little form-factor pluggable (SFP) is really a compact, hot-pluggable transceiver utilized for each telecommunication and data communications applications. The type aspect and electrical interface are specified by a multi-source agreement (MSA). It interfaces a network device motherboard (for a switch, router, media converter or similar device) to a fiber optic or copper networking cable. It’s a popular industry format jointly created and supported by many network component vendors. Cisco SFP transceivers are designed to assistance SONET, Gigabit Ethernet, Fibre Channel, and other communications standards. Because of its smaller sized size, Cisco SFP obsoletes the formerly ubiquitous gigabit interface converter (GBIC); the SFP is sometimes referred to as a Mini-GBIC although no device with this name has ever been defined within the MSAs.

So what’s GBIC? From the above paragraph we have known that GBIC is short for gigabit interface converter, which is a standard for transceivers, generally used with Gigabit Ethernet and fibre channel within the 1990s. By providing a regular, hot swappable electrical interface, 1 gigabit port can assistance a wide range of physical media, from copper to long-wave single-mode optical fiber, at lengths of a huge selection of kilometers. Cisco GBIC is really a transceiver that converts serial electric signals to serial optical signals and vice versa. In networking, a GBIC is utilized to interface a fiber optic system with an Ethernet method, such as Fibre Channel and Gigabit Ethernet. Cisco GBIC enables designers to design one kind of device that can be adapted for either optical or copper applications. Cisco GBICs also are hot-swappable, which adds towards the ease of upgrading electro-optical communication networks.

To supply larger capacity, we require a Cisco X2 transceiver. Cisco X2 transceiver will be the 10G fiber optic transceiver, whose improvement was primarily based on former XENPAK standards. Cisco X2 10GB transceiver inner function is almost similar with XENPAK, and X2 also can use one transceiver to fulfill all 10G Ethernet optical port function. Cisco X2 transceiver is about half size of Xenpak, this enable it suit for density installations. Cisco X2-10GB-SR is one of the most well-liked Cisco X2 transceivers. Cisco X2-10GB-SR module is really a multimode transceiver target in the 10G applications. It works with 850nm multimode fiber and also the optical interface is duplex SC. Cisco X2-10GB-SR modules can hyperlink the equipment to fiber optic networks, max transmission distance is 300 meters and support a hyperlink of max 300 meters via multimode fiber. It is utilized in 10Gigabit applications including Ethernet and Fibre channel.

Except SFP, GBIC, X2, there are aslo other Cisco fiber optic transceivers with various use. Such as XENPAK transceiver which we’ve refered within the introduction of Cisco X2. For more information, you are able to go to FiberStore, who’s the very best fiber optic products supplier from China.
