Description

The SFP-10G-RA-1G-LX is a rate-adapting SFP+ transceiver from the Arista optics range. It presents a 10G host interface to the switch while running a 1000BASE-LX link over duplex single-mode fibre, so a 10G SFP+ port can connect directly to legacy 1G-LX infrastructure. It suits migrations from 1G to 10G or 25G access and aggregation layers in data centre and campus networks.

The optic uses a 1310 nm wavelength and an LC duplex connector, with a reach of up to 10 km over G.652 single-mode fibre. Transmit power is -9.5 to -3.0 dBm and receive power is -19 to -3.0 dBm. Maximum module power is 2 W, drawn from the host switch port, and the operating case temperature range is 0 to 70 C. It is a different module from the non-rate-adapting SFP-1G-LX and from the multimode SFP-10G-RA-1G-SX. No licence is required for the transceiver itself.

It works on SFP+ ports and SFP25 ports, and on certain platforms in QSFP ports with a QSFP-to-SFP+ adapter. A minimum EOS release of 4.29.1 is required on the host switch, and support is limited to specific Arista platforms, so check the Arista Transceiver and Cable Guide platform table before ordering.

Enquire with XS Network Tech for new or used pricing and availability.

Features

- Rate adapting: the switch port runs at 10G while the optical link runs at 1G
- Connects a 10G SFP+ port to existing 1000BASE-LX single-mode links up to 10 km
- Hot-swappable pluggable optic
- Usable on SFP+ and SFP25 ports on supported platforms
- QSFP and QSFP-DD ports supported with a QSFP-to-SFP+ adapter on certain platforms
- Powered from the host switch port, so no separate power supply is needed

FAQs

Q: Does this transceiver need a licence or subscription?
A: No licence or subscription is needed for the transceiver itself. The host switch must run EOS 4.29.1 or later, and some platforms require a later release.

Q: How does it differ from the SFP-1G-LX and the SFP-10G-RA-1G-SX?
A: Unlike the SFP-1G-LX, this module is rate adapting, so it works in a 10G host port while the optical link runs at 1G. Unlike the SFP-10G-RA-1G-SX, it uses 1310 nm single-mode fibre for up to 10 km rather than multimode fibre.

Q: Which switches support it?
A: It is supported on specific Arista platforms only, including the 7050SX3-48YC8 and 7050SX3-48C8, 7280SR3 and 7280CR3 series, 720XP and 720DP series, and 7800R3 series. Check the Arista Transceiver and Cable Guide platform table before ordering.

Q: Can it be used in QSFP ports?
A: On some platforms it can be used in QSFP and QSFP-DD ports with a QSFP-to-SFP+ adapter. Support depends on the switch model.

Q: What fibre and connector does it use?
A: It uses duplex single-mode fibre (G.652) with an LC connector at 1310 nm, for links up to 10 km.
