Frequently Asked Questions
What cable does it need?
A 12-fiber MPO trunk with flat (UPC) endfaces on OM3 or OM4 multimode fiber, female on both ends. Angle-polished (APC) MPO cables, such as those built for NVIDIA NDR optics, will not mate with it.
Can it break out to 4 x 25G?
Yes, on switches that support breakout: an MPO to 4 x duplex LC breakout cable connects one SR4 port to four 25GBASE-SR SFP28 ports. The QSFP28 port must be set to 4 x 25G breakout mode.
SR4 or LR4: which do I need?
SR4 is for short multimode runs inside a data center (up to 100 m on OM4). LR4 runs up to 10 km over single-mode fiber with duplex LC connectors.
Compatible module or genuine Dell: what is the difference?
This is a new third-party module programmed (coded) to be recognized by Dell equipment that calls for this part number, at a fraction of the Dell-branded price. Choose the genuine Dell part only if your support contract or internal policy requires Dell-branded parts.
What warranty and shipping come with it?
Resilient Tec's lifetime warranty. US standard shipping is free with no minimum, and orders typically arrive in 3 to 5 days.
