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. Other model designations map to the same Part Number in HCT; primary specifications remain from SFP-1G-LH-C only. Standard SMF reach is 70 km; the source treats an 80 km link as an engineered low-loss example, not unconditional reach.
HCT interoperability and reach qualifications: SFP-1G-LH-C is rated for 70 km SMF with a 24 dB optical budget. The 80 km engineering example requires fiber attenuation <0.25 dB/km, connector loss <2 dB and 2 dB TDP; it is not the unconditional rated reach.
Other designations for the same P/N — verify HCT profile: EX-SFP-1GE-LH
