Frequently Asked Questions
Can I reuse my existing duplex LC multimode fiber?
Yes. That is the main reason to choose SR1.2: it runs 100G over the same two-fiber LC cabling used for 10G and 40G BiDi, so no MPO trunks are needed.
SR1.2 or SR4: which do I need?
SR4 needs an 8-fiber MPO trunk but the optics usually cost less. SR1.2 costs more per optic but reuses duplex LC fiber. Both ends of a link must use the same type.
Compatible module or genuine Cisco: what is the difference?
This is a new third-party module programmed (coded) to be recognized by Cisco equipment that calls for this part number, at a fraction of the Cisco-branded price. Choose the genuine Cisco part only if your support contract or internal policy requires Cisco-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.
