MTP® Elite Female-Female Patch Cord | Base-8 | Single Mode G657.A2 | 3.0mm
$7.50
Extend high-speed single mode links with this Base-8 MTP® Female-to-Female Extension Cable. Designed with Type A (straight-through) polarity, it couples two Male MTP-8 cables to create longer 100G DR4/PSM4 channels using bend-insensitive G.657.A2 fiber.
Overview
This Base-8 MTP® Elite Female-to-Female Patch Cord serves as a high-performance trunk or extension cable for single mode parallel optic networks. Equipped with unpinned Female MTP® connectors on both ends, it is specifically designed to couple two Male (pinned) MTP®-8 cables together. This allows you to extend the reach of your existing infrastructure or create backbone links between patch panels with maximum efficiency.
Engineered with 8 strands of premium G.657.A2 bend-insensitive single mode fiber and featuring standard Type A (straight-through) polarity, this cable preserves the polarity of the channel. It ensures a seamless, low-loss connection for demanding applications like 100G-DR4, 400G-DR4, and PSM4, maintaining signal integrity over extended distances within the data center.
Key Features
- Terminated with two Female (unpinned) MTP® Elite connectors for superior low-loss performance.
- Functions as an extension or trunk cable to connect two Male MTP® cables.
- Utilizes a Base-8 fiber configuration for 100% fiber utilization with parallel optics.
- Constructed with high-performance G.657.A2 bend-insensitive single mode fiber.
- Standard Type A (straight-through) polarity for predictable link extension.
- Yellow OFNP/LSZH jacket for easy identification and compliance with safety codes.
- Robust 3.0mm diameter suitable for structured cabling pathways and data center racks.
Applications
The primary function of this cable is to create longer channels within a structured cabling environment. It is not used for direct transceiver connections but rather for linking segments together. Its main applications include:
- Extending the reach of Male-to-Male MTP®-8 patch cords.
- Creating backbone (trunk) links between MTP® patch panels or cassettes.
- Use in multi-segment MTP® channels for 40G/100G/400G single mode applications.
- Connecting distribution areas to equipment areas in large data centers.

Cross-Platform Compatibility
As a trunk or extension cable, this assembly uses Type A (straight-through) polarity. This means each fiber position is mapped directly to the same position on the other end (1-to-1, 2-to-2, etc.). This design is critical for maintaining the polarity scheme of the overall channel. It allows a Type B patch cord at one end to correctly align Tx/Rx signals with another patch cord at the far end, with this cable acting as a simple, transparent extension.

| Pin 2 | → | Pin 2 |

FAQ (Technical & Product Questions)
1. What is the main purpose of a Female-to-Female MTP® cable?
Its main purpose is to connect two Male (pinned) MTP® cables, acting as an extension cord or a permanent trunk link within a structured cabling system. It is used to extend the distance between two points, such as between equipment racks or patch panels.
2. Can this cable connect directly to a transceiver like a QSFP28-DR4?
No. Transceivers have Female (unpinned) MPO ports and require a Male (pinned) cable connector. This Female-to-Female cable is designed to join two Male cables together, not to plug into equipment directly.
3. Why is the polarity Type A for this cable?
Type A (straight-through) polarity is the standard for MTP® trunk and extension cables. It ensures that the polarity of the channel is preserved. The required transmit-to-receive “flip” is handled by the Type B patch cords used at the ends of the link, not by the trunk cable in the middle.
4. What is the benefit of a Base-8 trunk cable?
A Base-8 trunk cable perfectly matches the 8-fiber requirement (4 Tx, 4 Rx) of modern parallel optic transceivers like DR4 and PSM4. This leads to a simpler, more cost-effective network design with 100% fiber utilization, as no fibers in the cable are left unused.
5. When should I choose G.657.A2 fiber for a trunk cable?
You should choose G.657.A2 bend-insensitive fiber for trunk routes that may involve tight turns or high-density cable trays inside a data center. This fiber type minimizes signal loss when bent, ensuring reliable performance and protecting the integrity of your high-speed links.
