Description
Why 0.9mm is used for high-speed multimode pigtails
| Cable Size | Typical Role |
|---|---|
| 0.9mm | Splice-in pigtails & optical modules |
| 2.0mm | Multimode patch cords |
| 3.0mm | Heavy-duty multimode jumpers |
The slim 0.9mm jacket allows easy routing inside QSFP, SFP, patch panels and splice cassettes, without crowding or stress.
Multimode optical performance
| Parameter | Typical Value |
|---|---|
| Fiber Type | Multimode OM3 / OM4 / OM5 |
| Core / Cladding | 50 / 125 µm |
| Polish Type | UPC |
| Insertion Loss | ≤ 0.30 dB |
| Return Loss | ≥ 35 dB |
| Wavelengths | 850 nm / 1300 nm |
| Supported Speeds | 10G / 25G / 40G / 100G (short reach) |
These values meet the requirements of high-speed Ethernet, Fibre Channel and data-center interconnects.
Connector & color coding
| Feature | Description |
|---|---|
| Connector Type | LC Simplex |
| Cable Diameter | 0.9mm |
| Ferrule | 1.25mm zirconia ceramic |
| Housing Color | Rose-Red (OM4 / OM5 identification) |
| Latching System | LC push-pull |
| Operating Temperature | –40°C to +75°C |
| Durability | ≥ 1000 mating cycles |
The rose-red housing allows technicians to instantly identify high-bandwidth multimode links in mixed-fiber racks.
Typical applications
This connector is widely used in:
-
OM4 / OM5 multimode pigtails

Professional Q&A
Q1: What does rose-red color indicate?
Rose-red is commonly used for OM4 and OM5 multimode fiber, which supports higher bandwidth and faster data rates than standard OM2/OM3.
Q2: Can this be used for 100G Ethernet?
Yes. When used with OM4 or OM5 fiber, this connector supports 100G short-reach links in data centers.
Q3: Can rose-red multimode connect to lake-blue multimode?
Yes, as long as both are multimode LC UPC. The color only indicates fiber grade, not connector compatibility.
