Cisco 10GBASE SFP+ Fiber Modules

The Cisco® 10GBASE SFP+ modules is one kind of fiber transceiver who offers customers a wide variety of 10 Gigabit Ethernet connectivity options for data center, enterprise wiring closet, and service provider transport applications.

Main features of Cisco 10GBASE SFP+ modules include: it has the smallest 10G form factor ,hot-swappable input/output device that plugs into an Ethernet SFP+ port of a Cisco switch and optical inter operability with 10GBASE XENPAK, 10GBASE X2, and 10GBASE XFP interfaces on the same link. What;s more, it supports not only 10GBASE Ethernet and OTU2/OTU2e, “pay-as-you-populate” model, digital optical monitoring capability, but also the Cisco quality identification (ID) feature that enables a Cisco switch to identify whether the module is certified and tested by Cisco.

Then, some introductions about different kinds of the Cisco 10GBASE SFP+ Modules.

>Cisco SFP-10G-SR

The Cisco SFP+ 10GBASE-SR Module 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.

The SFP-10G-SR price is favorable in Fiberyes. The following products price are favorable in Fiberyes.

>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-LR

The Cisco SFP+ 10GBASE-LR Module 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.

>Cisco SFP+ Twinax Copper Cables

Cisco SFP+ Copper Twinax direct-attach cables are suitable for very short distances and offer a cost-effective way to connect within racks and across adjacent racks. Cisco offers passive Twinax cables in lengths of 1, 1.5, 2, 2.5, 3 and 5 meters, and active Twinax cables in lengths of 7 and 10 meters.

>Cisco SFP-10G-LRM

The Cisco SFP+ 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. Note this product is not orderable individually.

How To Choose A Fiber Transceiver

How To Choose A Fiber Transceiver

Fiber transceiver used in the Ethernet cable cann't be overwritten, you must use the fiber to extend transmission distance of the actual network environment, help fiber last-km line to connect to the metro and the outer layer of the network playa huge role. With fiber optic transceivers, also need to upgrade from copper to fiber optic, but lack of funds, manpower or time the user provides an inexpensive program.

In order to ensure fully compatible with the NICs, repeaters, hubs and switches and other network equipment of other manufacturers, fiber optic transceiver products must strictly comply with 10Base-T, 100Base-TX, 100Base-FX, IEEE802.3 and IEEE802.3u Ethernet standard. In addition, EMC anti-electromagnetic radiation shall comply with FCC Part15. Nowadays, the major domestic carriers are great efforts to build the residential network, campus and enterprise networks, so the amount of fiber-optic transceiver products are constantly improved to better meet the access network construction needs.

How to choose a fiber transceiver? Due to fiber converter is one of the LAN connection device, it is necessary to consider the mutual compatibility with the surrounding environment, and product stability, reliability, and vice versa: the prices were lower, cann't get customer all like!

1. Whether to support full-duplex and half duplex?

Some chips on the market currently only use full-duplex environment, can not support half-duplex, such as the receipt of other brands of switches or HUB and it is using half-duplex mode, will cause serious conflict and loss.

2. Whether and other optical transceiver done connection test?

An increasing number of currently available fiber optic transceivers, transceivers, such as the mutual compatibility of different brands of transceivers in advance didn't make the test will produce loss, the transfer time is too long, suddenly fast and slow phenomena such as.

3. Whether there is a safety device to prevent packet loss?

Some vendors in the manufacture of fiber optic transceivers, transceiver, in order to reduce costs, often the data transfer mode register, this approach is the biggest drawback is instability in the transmission, packet loss, and the best is to use the buffer line. can be safe and to avoid data loss.

4. Temperature adaptability?

Fiber optic transceivers, when used, will produce high fever, high temperature (not greater than 85C), fiber optic transceiver is working properly? Is very worthy of the factors that customers consider!

5. Whether conforming to the IEEE802.3u standard?

Such as fiber optic transceivers comply with IEEE802.3 standard, that the delay time control in 46bit, it means that the transmission distance of fiber-optic transceiver will be shortened if more than 46bit!
