A data center needs to upgrade a 100-meter server-to-switch link to 40GBASE-SR4. What type of fiber and wavelength should they select for the most cost-effective solution?
Answers
AOM1 multimode fiber operating at 1550nm
BOS2 single-mode fiber operating at 1310nm
COM4 multimode fiber operating at 850nm
DOS1 single-mode fiber operating at 1625nm
Correct answer: C — OM4 multimode fiber operating at 850nm
For short data center runs (up to 150m) at 40Gbps or 100Gbps, OM4 multimode fiber using VCSEL lasers at 850nm is the standard, cost-effective choice (SR4).
