Description
What the rose-red housing actually means
In modern optical cabling, color is no longer decoration — it is a working tool.
The rose-red body identifies this connector as being intended for high-bandwidth multimode fiber, typically OM4 or OM5, which are used for:
-
40G and 100G Ethernet
-
High-speed SAN and storage networks
-
Data-center backbone links
Technicians can immediately recognize these jumpers in mixed racks that also contain aqua (OM3) and yellow (single-mode) cables.
Optical behavior you can rely on
Even with the heavy 3.0mm jacket, the connector still uses a precision 1.25mm zirconia ceramic ferrule and a UPC polished end face.
This combination provides stable physical contact between fibers, which is critical for short-reach multimode links running at very high data rates.
| Performance item | Typical level |
|---|---|
| Fiber type | OM3 / OM4 / OM5 (50/125 µm) |
| Polish | UPC |
| Insertion loss | ≤ 0.30 dB |
| Return loss | ≥ 35 dB |
| Working wavelengths | 850 nm, 1300 nm |
| Plug-unplug life | ≥ 1000 cycles |
These values are well within the limits required for 10G, 25G, 40G and 100G SR optics.
Built like a field jumper, not a lab cord
Where a 2.0mm duplex cable focuses on flexibility, the 3.0mm version focuses on survival.
| Construction element | What it does |
|---|---|
| 3.0mm outer jacket | Resists crushing and pulling |
| Long duplex boots | Absorb stress before it reaches the fiber |
| LC push-pull latch | Keeps connectors secure in crowded panels |
| Ceramic ferrules | Maintain stable alignment over time |
This makes the connector especially suitable for core racks, aggregation cabinets, industrial enclosures and telecom rooms, where cables are frequently handled.
Professional Q&A
Can this be mixed with aqua OM3 jumpers?
Yes. The connector is fully compatible with OM3, OM4 and OM5 multimode fiber. The rose-red color simply indicates higher-grade multimode.
Is 3.0mm really necessary indoors?
In quiet racks, 2.0mm is fine. In busy data-center rows, industrial cabinets or telecom frames, 3.0mm dramatically reduces cable damage and signal instability.
Can LC UPC be used with MPO-LC breakout cables?
Yes. This connector is commonly used at the LC end of MPO-LC fan-out assemblies for high-speed multimode links.
