Description

The Arista SFP-25G-LR is a 25GBASE-LR SFP28 optical transceiver for duplex single-mode fibre links up to 10 km. It operates at 1310 nm over a standard LC connector, making it well suited to campus, metro and data centre interconnects where 25G reach beyond multimode distances is required.

Built to the IEEE 25GBASE-LR specification and the SFP MSA standards, this module delivers a transmit power range of -7 to 2.0 dBm and a receive power range of -13.3 to 2.0 dBm. It is a distinct part from the low-latency SFP-25G-LR-E and the dual rate SFP-25G-MR-LR, so choose it when you need a standard 25G-only long-reach optic.

Features

- IEEE 25GBASE-LR compliant optics for duplex single-mode fibre links up to 10 km
- 1310 nm wavelength with a standard LC connector
- SFF-8431, 8461 and 8472 SFP MSA compliance as listed in the datasheet
- Distinct from the SFP-25G-LR-E low-latency E-series and the SFP-25G-MR-LR dual rate 10G/25G module

FAQs

Q: What fibre type does the SFP-25G-LR require?
A: It is designed for duplex single-mode fibre (G.652) and uses an LC connector, with a maximum reach of 10 km.

Q: What wavelength does this transceiver use?
A: It operates at 1310 nm.

Q: How does the SFP-25G-LR differ from the SFP-25G-LR-E?
A: The SFP-25G-LR-E is the low-latency E-series optic, while the SFP-25G-LR is the standard 25GBASE-LR module.

Q: How does it differ from the SFP-25G-MR-LR?
A: The SFP-25G-MR-LR is a dual rate 10G/25G module, whereas the SFP-25G-LR is a 25G 25GBASE-LR optic.
