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.
Is this an original Cisco part?
Yes, a Cisco-branded QSFP-100G-LR4-S, sold refurbished. It is also available new.
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.
