Description

The SFP-10G-RA-1G-SX is a rate adapting SFP transceiver with a 1000BASE-SX optical interface on the media side and a 10G host interface. It lets a 10G SFP+ port link to a 1G SX fibre connection over multimode fibre, with reach up to 550m on 50/125um MMF with 500 MHzkm modal bandwidth (OM2). It uses an LC connector and an 850 nm wavelength.

This module is suited to migrations and mixed-speed environments where a 10G SFP+ switch port needs to connect to existing 1G 1000BASE-SX optics. Rate adapting transceivers are supported only on specific Arista platforms, so check the Arista Transceiver and Cable Guide before deployment. On shorter links, proper optical attenuation is needed to protect the receiver.

Features

- Rate adapting: a 10G SFP+ host port connects to a 1G 1000BASE-SX link
- Supports 1000BASE-SX reach up to 550m on OM2 multimode fibre
- LC connector with 850 nm optics for standard multimode cabling
- Low power consumption of 2 W maximum
- Supported on specific Arista platforms only

FAQs

Q: What does rate adapting mean for this transceiver?
A: The module presents a 10G host interface to the switch port while running a 1000BASE-SX optical link on the media side. This lets a 10G SFP+ port connect to a 1G SX fibre link.

Q: What fibre type and maximum distance does it support?
A: It runs over multimode fibre with LC connectors at 850 nm. Reach is up to 550m on 50/125um MMF with 500 MHzkm modal bandwidth (OM2), 500m at 400 MHzkm, 275m on 62.5um at 200 MHzkm and 220m on 62.5um at 160 MHzkm.

Q: Will it work in any 10G SFP+ port?
A: No. Rate adapting transceivers are supported only on specific platforms. Check Arista's Transceiver and Cable Guide to confirm your switch model supports this module.

Q: Do I need attenuation on short links?
A: Proper optical attenuation is needed on shorter links to protect the receiver. Rx power range is -17 to 0.0 dBm.

Q: What is the power consumption?
A: Maximum power consumption is 2 W.

Q: What is the operating temperature range?
A: The operating case temperature range is 0 to 70 C, with a storage range of -40 to 70 C.
