Documented selection limits

Reach, rate, form factor and breakout support apply only to the listed standard/mode, fiber grade and platform/port configuration. Keep source qualifiers for FEC, attenuation, transmit/receive limits, temperature, active/passive operation and cable ends. Check Juniper HCT for the exact host, interface module, port mode, Junos release, required QSA adapter and qualifications before ordering. Do not infer universal interoperability or combine power/temperature/reach across model profiles. Optical link budgets are not calculated or inferred. Parallel fiber/core/modal-bandwidth/distance values retain the same source column order; correlate matching columns instead of applying the largest distance to every fiber.

Reading parallel values

Pipe-separated fiber, bandwidth and reach values correspond by position in the original manufacturer column order. The longest reach does not apply to every fiber type.
