Frequently Asked Questions
DAC or optics with fiber: which should I use?
For short in-rack runs, a passive DAC costs less, draws almost no power and adds less latency than two optics plus a fiber cable. Passive 100G DACs are made for runs of a few meters; for longer runs use optics with fiber or an active optical cable.
Does it need power or configuration?
No. It is passive copper with no optics; the port reads its coding and brings the link up as 100GBASE-CR4.
Compatible cable or genuine Juniper: what is the difference?
This is a new third-party cable programmed (coded) to be recognized by Juniper equipment that calls for this part number, at a fraction of the Juniper-branded price. Choose the genuine Juniper part only if your support contract or internal policy requires Juniper-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.
