A practical guide to selecting SMF or MMF for 100G interconnects, with a worked example and verification steps.
A practical guide to choosing between DWDM and CWDM for a fiber link. Covers capacity trade-offs, an 80 km metro worked example, and verification steps for wavelength alignment, BER and dispersion.
Explains how to replace thread pools with virtual threads for I/O‑bound Java services, covering pinning risks, ThreadLocal limits, and verification steps.
Learn how bend‑insensitive SMF reduces macrobend loss in dense rack‑to‑rack links, see a sample 10 GbE calculation, and verify performance with simple field tests.
In a Fiber application, I need to parse incoming ISO‑8601 timestamps from JSON payloads, interpret them as UTC, then convert to a user‑specified regional time zone (e.g., America/New_York) for storage or display. The standard library time package offers conversion, but I am unsure how to handle ambiguous or non‑existent times during DST transitions safely wi
