Juniper JNP-100G-DAC Compatible 100G QSFP28 Passive DAC Cable — 2m, JNP-100G-DAC-2M-C
Warranty: Lifetime
Juniper-to-Juniper 100G at 2 meters — between the 1 m and 3 m stock lengths
JNP-100G-DAC-2M-C — Juniper compatible 100G QSFP28 to QSFP28 passive DAC, 2m
→ Juniper coding on both ends. For switch-to-switch links between Juniper platforms, for example a PTX10002-60C to a QFX5200-32C as our customers use it.
SKU: JNP-100G-DAC-2M-C
Description: 100G QSFP28 passive direct-attach copper cable, 4x 25G NRZ, Juniper coding on both ends, 2 m
A 100G QSFP28 passive DAC is the lowest-latency, lowest-power way to link two Juniper ports in the same or adjacent rack. Juniper lists its own passive 100G DACs as 26 AWG twinax rated 0 to 70°C.
Choose 2 m when 1 m is too short and 3 m would leave a loop of slack in the rack.

Good to Know
- FEC must match. At 100G both ports need the same FEC setting.
- Breakout is a different cable. For 100G to 4x 25G use a breakout DAC, not this cable.
Quick Checklist — Is This the Right Cable?
You are linking two Juniper 100G QSFP28 ports within 2 m.
