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.
