Why Choose 10GBASE-T SFP+ Transceiver for 10G Network Connection?

Over the years, 40G and 100G networks are developing rapidly, but nearly all new network building or network upgrading are based on 10G network. As an indispensable part in 10G network building, 10G optical transceiver has been designed and standardized by IEEE group as early as 2006. Compared with the prevalent 10GBASE-SR, 10GBASE-LR optical modules on the 10G transceiver market, 10GBASE-T SFP+ copper transceiver receives little attention. Different types have their own pros and cons, so why should we choose 10GBASE-T SFP+ transceiver for 10G network connection instead of others? This article would provide a satisfying answer for you.

Basic Information About 10GBASE-T SFP+ Transceiver

10GBASE-T meets all the bit-error rate (EDR) requirements of all the Ethernet and storage over Ethernet specifications, which is specifically designed for high speed communication links that require 10G Ethernet over cat6a or cat7 cable. It uses the familiar RJ45 connector and provides backward compatibility with legacy networks. 10GBASE-T SFP+ transceiver allows 10G bandwidth over existing infrastructrue and supports links up to 100 m using cat6a/7 cabling. It is compatible with a range of OEM’s including Cisco, Arista, Brocade, Juniper, Dell, Extreme, IBM. The 10GBASE-T SFP+ transceiver is available to many application equipment, including hubs, switches, routers, and switched interfaces on work area equipment.

The Benefits of 10GBASE-T SFP+ Transceiver

• Low cost solutions are market stimulus

—Cost effective at up to 100 m distance

—Addresses PHY costs concerns in Enterprise market

—Enhances reach and conforms to structured cabling environment

• Low cabling costs

—Ease and reuse of standard/structured cabling

—Ease of 1GBASE-T to 10GBASE-T migration

—Overall migration towards 10G Ethernet

• High flexibility

—Multi-speed flexibility: Platforms support dual speed (1000BASE-T/10GBASE-T) or triple speeds (100BASE-T/1000BASE-T/10GBASE-T)

—Architecture Flexibility: Supports Top of Rack, Middle of Row or End of Row architectures

Why Choose 10GBASE-T SFP+ for Connection?

On the current 10G optical transceiver market, Direct Attach (DA) copper, 10GBASE-SR, 10GBASE-LR are highly favored by many Ethernet users. The DA copper seems cost less than the other 10G transceivers, but it has two major limitations: DA’s range is limited to 7 m; And because of the SFP+ connector, it is not backward-compatible with existing 1HbE infrastructure using RJ-45 connectors and twisted-pair cabling. By using 10GBASE-T copper transceiver, these limitations can be addressed. 10GBASE-T delivers 10GbE over cat6a or cat7 cabling terminated with RJ-45 jacks. It is backward-compatible with 1GbE and even 100Mgb Ethernet. Cat6a and cat7 cables will support up to 100 m.

In an existing data center, using 10GBASE-T SFP+ transceiver is quite convenient and efficient. Cat6 or more better twisted pair cabling rating have already been deployed in most existing data centers.10GBASE-T can be added incrementally to these data centers, either in new servers or via NIC upgrades “without forklifts”. New 10GBASE-T ports will operate with all the existing Ethernet infrastructure in place. With the upgrading of switches to 10GbE BASE T at whatever pace, the only effect will be noticeably enhanced network bandwidth.

Conclusion

As we discussed in this passage, 10GBASE-T SFP+ copper transceiver provides a cost-effective solution for 10G Ethernet network. It is of high port density, relatively high power and great flexibility. Thus, using 10GBASE-T SFP+ transceiver for building a new network or network upgrading is really a good deal.
