10G SFP+ Overview

The 10G SFP+ category contains three transceiver modules for 10G connections in data centers, enterprise wiring closets, service provider transport networks, and radio and baseband unit links. All models use the SFP+ form factor and support transmission distances from 30m to 10km. The series includes one copper transceiver with an RJ45 interface, one multimode optical transceiver, and one single-mode optical transceiver. The optical models use duplex LC/UPC connectors and support DOM monitoring. These modules also support campus and data center deployments involving 10G downlinks, 40G uplinks, and 40G-to-4×10G breakout connections.

SFP-10G-T-30 This 10GBASE-T SFP+ copper transceiver provides a 10G electrical connection through an RJ45 interface and supports transmission distances up to 30m. It is used for short-reach links in data centers, enterprise wiring closets, campus networks, and service provider environments where an SFP+ port must connect through copper cabling.

SFP-10G-SR This 10GBASE-SR SFP+ optical transceiver operates at 850nm over multimode fiber and uses a duplex LC/UPC connector. It supports transmission distances up to 400m and incorporates DOM monitoring. The module provides short-reach 10G links in data centers, enterprise wiring closets, campus networks, service provider transport applications, and connections involving radio and baseband units.

SFP-10G-LR This 10GBASE-LR SFP+ optical transceiver provides 1310nm transmission over single-mode fiber through a duplex LC/UPC connector. It supports optical links up to 10km and includes DOM monitoring. The module is designed for longer-reach 10G connections across data centers, campus networks, enterprise infrastructure, service provider transport systems, and radio and baseband unit applications.

FAQ

What are the practical interface, transmission media, and reach differences among SFP-10G-T-30, SFP-10G-SR, and SFP-10G-LR?

SFP-10G-T-30 provides an RJ45 copper link up to 30m. SFP-10G-SR uses 850nm multimode fiber with duplex LC/UPC connectors up to 400m. SFP-10G-LR uses 1310nm single-mode fiber with duplex LC/UPC connectors up to 10km. The two optical models support DOM.

Which copper cabling and connector should be used to achieve the specified 30m 10G link with SFP-10G-T-30?

Use an RJ45 connection with Cat6A, Cat7, or better twisted-pair cabling for a 10Gb/s link up to 30m. The SFP-10G-T-30 connects an SFP+ host port to a copper 10GBASE-T endpoint.

Which multimode fiber type is required for SFP-10G-SR to reach its maximum stated transmission distance of 400m?

OM4 multimode fiber supports the full 400m reach. OM3 supports links up to 300m. The SFP-10G-SR operates at 850nm and uses a duplex LC/UPC interface with two fiber strands.

What fiber, connector, and wavelength configuration does SFP-10G-LR use for a 10km 10G optical link?

It uses 1310nm transmission over standard single-mode fiber and a duplex LC/UPC connector. The SFP-10G-LR supports point-to-point 10G optical links up to 10km using separate transmit and receive fiber strands.

Which models in the 10G SFP+ category support DOM, and is this function specified for SFP-10G-T-30?

SFP-10G-SR and SFP-10G-LR support DOM, allowing compatible host equipment to read optical operating information. DOM is not specified for SFP-10G-T-30 in the provided product information, so this function should not be assumed for the copper model.

Can SFP-10G-SR and SFP-10G-LR serve as the 10G endpoints of 40G-to-4×10G optical breakout connections?

Yes. SFP-10G-SR can connect to a compatible 40GBASE-SR4 breakout over multimode fiber, while SFP-10G-LR requires a compatible 4×10G LR breakout solution over single-mode fiber. The 40G host port must support four independent 10G lanes and the corresponding breakout cabling.

Can the transceivers in the 10G SFP+ category be inserted or replaced without powering down compatible network equipment?

Yes. The SFP+ form factor is hot-swappable, allowing the modules to be inserted or removed without shutting down compatible host equipment. The individual network link will be interrupted while its transceiver is being replaced.
