What Is an MPO Cable? Intro to MTP/MPO Fiber Patch Cords
What Is an MPO Cable? A Technical Introduction to MTP/MPO Fiber Patch Cords
An MPO (Multi-Fiber Push-On) cable is a high-density fiber optic interconnect designed to aggregate multiple optical fibers into a single connector, enabling rapid deployment and space savings in modern network environments. The MTP (Multi-Fiber Termination Push-on) connector is a enhanced, fully compliant variant of the MPO standard, often used interchangeably in industry discussions. This guide explains the fundamentals, key specifications, and practical selection criteria for MPO/MTP patch cords, with a focus on solutions from FOCC Fiber Co.,Ltd., a manufacturer established in 2014 with over a decade of experience.

As data centers scale to 400G and 800G speeds, and 5G networks require fiber-to-the-antenna (FTTA) architectures, traditional LC/SC duplex connectors become a bottleneck due to physical space and installation time. A single MPO connector can house 12, 16, 24, or even 48 fibers in one ferrule, reducing cable volume by up to 80% and cutting deployment labor significantly. The challenge is selecting the right MPO patch cord that meets optical performance, environmental, and compliance criteria.
FOCC Fiber’s MPO/MTP Patch Cord Overview
FOCC Fiber Co.,Ltd., headquartered in Shenzhen, China, specializes in high-performance, high-density, and high-reliability fiber optic interconnects. The company’s MPO/MTP Fiber Optic Patch Cord product line includes models such as MPO-12-OS2-APC, MTP-24-OM4-UPC, and MTP-48-OM3-UPC. These patch cords are designed for data center cabling and telecommunication applications, offering core counts of 12, 16, 24, or 48 fibers. Available fiber types include single-mode OS2 and multi-mode OM3, OM4, OM5.

- Insertion Loss: Elite grade ≤0.35 dB; Standard grade ≤0.5 dB (Telcordia GR-326 compliant)
- Return Loss: ≥60 dB (APC polish) / ≥50 dB (UPC polish)
- Operating Temperature: -20°C to +70°C
- Cable Length: Customizable from 1 m to 100 m
- Jacket Material: LSZH (Low Smoke Zero Halogen) for indoor compliance, also available in PVC
- Construction: Zirconia ceramic ferrule, PBT/PEI housing, Kevlar aramid yarn strength member
Step-by-Step Guide to Selecting an MPO Patch Cord
- Determine Fiber Count: For typical 40G/100G links, 12-fiber (12F) MPO is common. For 400G SR8, 16F or 24F may be needed. FOCC offers 12/16/24/48 cores.
- Choose Fiber Type: Single-mode OS2 for long-reach (>300m) and high-speed coherent optics; multi-mode OM3/OM4 for short-reach 100G/400G within data centers; OM5 for SWDM applications.
- Select Polish: APC (Angled Physical Contact) yields higher return loss (≥60 dB) and is preferred for single-mode and high-precision links; UPC (Ultra Physical Contact) is typical for multi-mode and some single-mode applications.
- Specify Length: Standard lengths from 1 m to 100 m; FOCC Fiber offers customization.
- Evaluate Jacket Rating: For data center environments, LSZH is recommended to reduce toxic smoke. For outdoor or harsh indoor conditions, armored or waterproof variants may be required.
Use Cases for MPO/MTP Patch Cords
High-Density Data Centers
In modern hyperscale data centers, MPO patch cords connect switches to servers, storage, and optical transceivers at 400G/800G rates. The high fiber count reduces patch panel space and airflow obstruction. FOCC Fiber’s MPO/MTP patch cords are used in clean-room environments with low insertion loss and LSZH jackets.

While this article focuses on MPO/MTP cables, FOCC Fiber also offers outdoor waterproof FTTA patch cords (not the subject here) which use ODC connectors. However, MPO trunk cables can be used in indoor/backhaul portions of 5G networks where high-density pre-terminated cabling is beneficial.
Comparison: MPO vs. MTP Connector Types
| Feature | Standard MPO Connector | MTP Connector (US Conec) |
|---|---|---|
| Ferrule Technology | Standard MT ferrule | Enhanced MT ferrule with floating guide pins |
| Insertion Loss Typical | ≤0.5 dB (standard grade) | ≤0.35 dB (low-loss grade) |
| Interchangeability | Fully interoperable with MTP | Fully interoperable with MPO |
| Applications | General data center, telecom | High-performance 400G/800G, military |
Note: FOCC Fiber’s MPO/MTP patch cords are designed to be fully compatible with both MPO and MTP interfaces, meeting Telcordia GR-326 standards.
Frequently Asked Questions
What is the difference between MPO and MTP connectors?
MPO (Multi-Fiber Push-On) is the industry standard defined by IEC 61754-7 and TIA-604-5. MTP is a registered trademark of US Conec and represents a high-performance version of the MPO with tighter tolerances, floating ferrule, and improved optical performance. Both are intermateable, but MTP typically offers lower insertion loss and better durability.
What is the typical insertion loss for an MPO patch cord?
For standard grade MPO patch cords, insertion loss is ≤0.5 dB, while elite grade (low loss) achieves ≤0.35 dB, as specified by FOCC Fiber’s MPO/MTP product. These values comply with Telcordia GR-326 requirements.
Can MPO cables be used outdoors?
Standard indoor MPO cables with LSZH jackets are not rated for outdoor exposure. For outdoor installations, FOCC Fiber provides IP67/IP68-rated outdoor waterproof FTTA patch cords with ODC connectors, which are designed for -40°C to +75°C and high tensile strength.
What fiber counts are available for MPO patch cords?
FOCC Fiber offers MPO/MTP patch cords in 12, 16, 24, and 48 fiber configurations. Models include MPO-12-OS2-APC, MTP-24-OM4-UPC, and MTP-48-OM3-UPC.
