The most popular pluggable form factor is now available as a 10GBASE-T SFP+ transceiver module giving data center architects a new upgrade option by utilizing unused server ports and existing copper cabling.
The SFP+ (enhanced small form factor pluggable) transceiver, featured prominently in data center networks at 10Gb/s, is used in “access” or “network edge” equipment including: fabric extenders, access cards, top-of-rack (ToR) switches and leaf switches. Today the availability of a 10GBASE-T SFP+ transceiver module enables another dimension of flexibility for the Network Equipment Designer and for the Data Center professional looking to take advantage of existing copper channels in performance switches and routers.
The all new GLC-T-10G uses the popular SFP+ form factor – gives data center architects new options for connectivity in formerly unused server space.
The last three years have seen the broad adoption of 10Gb/s connectivity at network edge equipment. Network access connectivity requires careful planning related to CAPEX and the subsequent implications for ongoing operating expense. While optical fiber is the current connectivity solution of choice in the core or spine due to high aggregated data bandwidth or where link lengths can be measured in hundreds of meter, Cat 6a unshielded twisted pair (UTP) cannot be beaten for cost, proven performance and ease of installation for network edge and 10Gb/s trunk lengths up to 100m. As reliable as the Cat 6a structured cabling ecosystem is, the relatively high power consumption of physical layer PHY silicon has motivated a variety of access connectivity solutions to proliferate in the marketplace that aren’t interested in capitalizing on the benefits of Cat 6a UTP.
Evolving Data Center
The evolving data center network function virtualization (NFV), and unified data and storage networking have been broadly adopted today to migrate traditional, logical-only IT infrastructure to an abstracted virtual data center. Virtualization enables asset consolidation. It also allows for increased machine utilization, 20% to 60% at a minimum, meaning less space is required with lower power and cooling costs. Virtualized resources can be rapidly scaled and provisioned to meet often unpredictable demands and allow enterprises to innovate and roll out new networking services to maintain a competitive edge. With improvements in utilization and virtualized assets, servers are now seeing increased I/O demands. To keep pace with the increased I/O demand, network access line rates have migrated from 1Gb/s to 10Gb/s. Several connectivity solutions exist to service these network access needs including direct-attach cables (DAC), optical transceiver modules and embedded 10GBASE-T RJ45 ports. Each come with its own set of distinct advantages and disadvantages but only one new solution offers the potential to deliver power saving connectivity utilizing Cat 6a cable infrastructure with pay-as-you-grow flexibility.
Data Centers are taking advantage of Network Function Virtualization (NFV) enabling asset consolidation.
Why Use a 10GBase-T SFP+ Transceiver Module?
There are many reasons to consider using a 10GBASE-T copper SFP+ transceiver module:
- Reach: Up to 30m over CAT6a UTP cable, sufficient for all network access use cases
- Cost: Pay-as-you-grow model that performs for today and scales for tomorrow
- Reliability: The RJ45 connector interface is rock solid. No surprises when deployed in your data center
- Innovation: Hot –pluggable with a managed soft-start
- Performance: Full PHY presentation, which means nothing is missing
- Smaller Footprint: Interoperable with any SFP+ cage and connector system
The new 10GBASE-T SFP+ transceiver module delivers compatibility with Cat 6a UTP structured cabling, up to 30m link distance, at a minimum of 0.5W power saving per port embedded over 10GBASE-T RJ45 ports. It also offers a pay-as-you-grow model representing a flexible and optimized solution for 10Gb/s network access connectivity.
