Frequently Asked Questions
What fiber does it use?
Single-mode OS2 (9/125 µm) fiber with duplex LC connectors. It will not work over multimode fiber.
LR4 or SR4: which do I need?
LR4 is for single-mode runs up to 10 km, such as between buildings or rooms. SR4 is the lower-cost choice for multimode runs up to 100 m inside a data center, using MPO cabling.
Can I connect it to an LR4 optic from another brand?
Yes. 100GBASE-LR4 is an IEEE standard, so it links with any LR4 optic on the far end, regardless of which switch brand it is coded for.
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.
