JNP-100G-AOC-xM-BCC | Juniper Compatible QSFP to QSFP Active Optical Cable, 100GBASE-AOC | 1 to 30M

Q: Will this work in place of the Juniper JNP-100G-AOC-1M?
A: Yes. The JNP-100G-AOC-xM-BCC is a plug-and-play replacement delivering 100 Gigabit per second over the same QSFP28 form factor, 850nm wavelength, and multi-mode fibre as the Juniper original. It complies with 100GBASE-AOC and QSFP28 MSA standards, ensuring compatibility with any Juniper switch or router that lists the JNP-100G-AOC-1M as supported.

Q: Which Juniper platforms support this active optical cable?
A: This cable works with any Juniper platform that has QSFP28 ports and supports 100GBASE-AOC or 100 Gigabit Ethernet over active optical cables. Compatible platforms include QFX, EX, and PTX series switches and routers. Verify your specific model lists QSFP28 AOC support in the hardware compatibility tool or data sheet.

Q: What is the maximum transmission distance and does it depend on fibre type?
A: The cable supports up to 100 metres over OM4 multi-mode fibre and 70 metres over OM3 multi-mode fibre per the 100GBASE-SR4 standard embedded in the AOC design. The fibre is integrated into the cable assembly, so no external fibre selection is required. The physical cable length you order (1M to 30M) determines the span.

Q: Can I mix different cable lengths in the same switch or between switches?
A: Yes. Each cable operates independently, so you can deploy 1M, 10M, and 30M cables in the same chassis without signal integrity issues. The VCSEL transmitters and PIN receivers at each end are tuned for the specific cable length, so mixing lengths does not affect bit error rate or timing as long as each cable stays within its rated distance.

Q: Does this cable require forward error correction (FEC) to be enabled on the host ports?
A: FEC is not required for this active optical cable to operate. The 100GBASE-AOC standard does not mandate FEC for links under 100 metres over multi-mode fibre. However, if your switch or router enables FEC by default (common on 100 Gigabit Ethernet ports), the cable will interoperate transparently. FEC can improve margin on longer cables or in electrically noisy environments.
