Lenovo Dual Rate 10G/25G SR SFP28 85C Transceiver

One module, two speeds: the 4TC7A69045 runs at 10G or 25G, so the same optic works while a network is moving from one speed to the other. It is an SFP28 SR module for multimode fiber, and the 85C in the title refers to its temperature rating.

That rating matters in warm racks and dense chassis, where airflow around the ports is limited and a standard optic could run near its limit. If your equipment runs hot, an 85C module gives more margin.

Send us the model of the switch or adapter at each end. Lenovo's feature code is BF10.

The 4TC7A69045 is offered refurbished and used only; no new offer is listed. Refurbished units carry a choice of 1 year or 3 years of warranty, and used units carry 90 days. Request pricing with your quantity.
