JNP-QSFP28-100G-SR4 Optical Transceiver
The Juniper JNP-QSFP28-100G-SR4 is a 100GBASE-SR4 QSFP28 optical transceiver designed for short-reach 100 Gbps links over multimode fiber, making it a standard choice for data center spine-leaf and top-of-rack cabling within racks and adjacent rows. It suits network integrators and enterprise data center buyers provisioning Juniper switch platforms with MPO/MTP-terminated OM4 infrastructure. As with any branded optic, confirm switch-side compatibility and firmware support before deploying third-party or matched inventory.
Key specifications (table)
| Model | JNP-QSFP28-100G-SR4 |
| Type | QSFP28 Optical Transceiver |
| Data Rate | 100 Gbps |
| Channels / Baud Rate | 4 × 25 Gbps (parallel SR4 lane architecture) |
| Transmission Distance | Up to 100 meters (using OM4 multimode fiber) |
| Wavelength | 850 nm (VCSEL-based, typical for MMF short reach) |
| Interface | MPO/MTP multi-fiber connector |
| Fiber Type | Multimode fiber (MMF) |
| Form Factor | QSFP28 (hot-pluggable) |
| Standards Compliance | IEEE 802.3bm 100GBASE-SR4 |
| Modulation | NRZ (Non-Return-to-Zero) |
| Power Consumption | ≤ 3.5 W |
| Operating Temperature | 0°C ~ 70°C |
| Storage Temperature | -40°C ~ 85°C |
Good to know
- The 4×25 Gbps parallel-lane design requires an MPO/MTP-12 patch infrastructure on the OM4 side — verify polarity (Method B/C) and connector quality, as MPO contamination is the most common cause of SR4 link errors.
- Within the 100G transceiver family, SR4 occupies the lowest-cost, shortest-reach tier; for runs beyond 100 m, LR4 (single-mode, 10 km class) optics are the usual next step, trading higher optic and fiber cost for reach.
- Order matched quantities per link (two modules plus MPO trunk or cassette cabling) and confirm whether your deployment requires original, Juniper-coded, or compatible-coded units based on your switch vendor’s coding policy.
