Lenovo 100GBase-SR4 QSFP28 Transceiver

The 4TC7A86257 is Lenovo's 100GBase-SR4 transceiver, a QSFP28 module for 100Gb Ethernet over short-reach optics. SR4 uses four parallel lanes inside one pluggable body.

Besides the connector and feature code (BVA4), check the media type, distance and host compatibility before ordering. That is typical of a generic optic, and it means the check falls to you. Confirm the fiber and the connector style on your patch panels, and send us the models of the switch and adapter so that we can verify support.

Buyers usually need these in pairs. Ordering both ends from one batch keeps the link behavior predictable.

If your build sheet names BVA4 specifically, this is the one.

The 4TC7A86257 is available new, refurbished and used. New and refurbished units carry a choice of 1 year or 3 years of warranty, and used units carry 90 days.
