Description

The QSFP-100G-SWDM4 is a 100GBASE-SWDM4 QSFP28 optical transceiver from the Arista optics range. It carries 100GbE over duplex LC multi-mode fibre, so data centre and campus teams can move from 10G or 40G duplex links to 100G without re-cabling to parallel MPO fibre.

It uses four short-wavelength lanes at 850, 880, 910 and 940 nm over 50.0 um multi-mode fibre. Reach is up to 70m on OM3 and up to 100m on OM4. Each lane transmits between -7.5 and +3.4 dBm and receives between -9.3 and +3.4 dBm. Maximum power draw is 3.5 W per module, supplied by the host QSFP28 port. Digital Optical Monitoring is supported for link quality visibility. No licence or subscription is required.

The module works in Arista switches with QSFP100 or QSFP28 ports and interoperates with other 100GBASE-SWDM4 optics. Check the Arista Transceiver and Cable Guide for platform and EOS support. The QSFP-100G-SR1.2 and QSFP-100G-SRBD are different 100G duplex multi-mode optics and are not the same module.

FAQs

Q: Does this transceiver need a licence or subscription?
A: No. It is a passive optical module and needs no licence or subscription.

Q: What fibre and distance does it support?
A: It uses duplex LC multi-mode fibre, reaching 70m on OM3 and 100m on OM4.

Q: Which switches does it work in?
A: It works in Arista switches with QSFP100 or QSFP28 ports. Check the Arista Transceiver and Cable Guide for platform and EOS support.

Q: How is it different from the QSFP-100G-SR1.2 or QSFP-100G-SRBD?
A: Those are separate 100G duplex multi-mode optics. This module is a 100GBASE-SWDM4 optic using four wavelengths from 850 to 940 nm.

Q: Can it link to other vendors' 100GBASE-SWDM4 optics?
A: Yes. It follows the 100G SWDM4 Alliance specification and interoperates with other 100GBASE-SWDM4 optics.
