Description

This Arista 100GBASE-LRL4 QSFP28 transceiver provides a 100G link over duplex single-mode fibre with a duplex LC connector. It suits data centre and campus links such as leaf-spine interconnects and inter-building runs, where the 10km reach of LR4 is not needed.

The module reaches up to 2km over G.652 single-mode fibre using four LAN-WDM lanes at 1295.56, 1300.05, 1304.58 and 1309.14 nm. Transmit power is -6.0 to +4.5 dBm per lane and receive power is -10.0 to +4.5 dBm per lane. Maximum power consumption is 4.0W, drawn from the host switch port, and the operating case temperature range is 0 to 70C.

It fits QSFP/QSFP28 100G ports on Arista switches and interoperates optically with 100GBASE-LR4 at up to 2km. An ADPT-O-Q-100G adapter allows 100G QSFP optics to be used in OSFP ports configured for 100G.

FAQs

Q: How far does the 100GBASE-LRL4 module reach?
A: It reaches up to 2km over duplex G.652 single-mode fibre with LC connectors.

Q: Can it link to a 100GBASE-LR4 optic at the other end?
A: Yes. It interoperates optically with 100GBASE-LR4 optics, with the link limited to 2km.

Q: Does it need external power?
A: No. It draws a maximum of 4.0W from the host switch QSFP port.

Q: Which ports does it fit?
A: It fits QSFP/QSFP28 100G ports on Arista switches. An ADPT-O-Q-100G adapter lets 100G QSFP optics be used in OSFP ports configured for 100G.

Q: Does it require a licence?
A: No licence is needed for the transceiver itself.
