Description

The Arista QSFP-100G-ER1 is a 100GBASE-ER single-lambda QSFP28 transceiver from Arista's 100G QSFP optics range. It carries 100 Gigabit Ethernet over duplex single-mode fibre with a duplex LC connector at 1310nm, reaching up to 40km. That makes it suited to data centre interconnect (DCI), campus or metro links and inter-building connections.

On the numbers, the module uses the 100GBASE-ER PHY over standard G.652 single-mode fibre, with a transmit power of +1.7 to +7.1 dBm and a receive power range of -16 to -3.4 dBm. Maximum power consumption is 4.5 W, drawn from the host switch QSFP port. Operating case temperature is 0 to 70 C. Optical attenuation is required on shorter links to protect the receiver from permanent damage.

It is designed for 100G QSFP/QSFP28 ports on supported Arista switches and routers. Check Arista's Transceiver and Cable Guide for supported platforms and minimum EOS versions. For a different 40km 100G option in the same range, see the QSFP-100G-ERL4.

FAQs

Q: What fibre type and connector does this transceiver use?
A: It uses duplex single-mode fibre (G.652) with a duplex LC connector at 1310nm.

Q: Is optical attenuation needed on short links?
A: Yes. Attenuation is required on shorter links to protect the receiver from permanent damage, because the transmit power is high for a 40km optic.

Q: What power does it draw?
A: Maximum power consumption is 4.5 W, supplied by the host switch QSFP port, so no separate power supply is needed.

Q: Which ports and platforms is it designed for?
A: It fits 100G QSFP/QSFP28 ports on supported Arista switches and routers. Check Arista's Transceiver and Cable Guide for supported platforms and minimum EOS versions.

Q: How does it differ from the QSFP-100G-ERL4?
A: The QSFP-100G-ER1 is a single-lambda 100GBASE-ER optic with a duplex LC connector. The QSFP-100G-ERL4 is Arista's other 40km 100G option in the same range.
