MTP® Elite Male-Male Patch Cord | Base-8 | Single Mode G657.A2 | 3.0mm
$8.10
Establish a direct, high-performance link between 40G/100G/400G parallel single mode transceivers with this Base-8 MTP® Male-to-Male Patch Cord. It features 8 G.657.A2 fibers and Type B polarity for a plug-and-play solution in DR4 and PSM4 applications.
Overview
This Base-8 MTP® Elite Male-to-Male Patch Cord is engineered for high-speed direct connections in advanced data centers. It uses an 8-fiber (Base-8) configuration with pinned Male MTP® connectors on both ends. This design is optimized for linking two parallel single mode transceivers, such as 100GBASE-DR4 or 40GBASE-PSM4, ensuring 100% fiber utilization for maximum efficiency and cost-effectiveness.
Constructed with 8 strands of premium G.657.A2 bend-insensitive single mode fiber, this cable delivers exceptional performance even in tight-spaced, high-density environments. The standard Type B (Reversed) polarity automatically maps the transmit (Tx) fibers to the receive (Rx) fibers, creating a seamless plug-and-play channel between two active devices without the need for additional polarity-flipping components.
Key Features
- Terminated with two Male (pinned) MTP® Elite connectors for superior low-loss performance.
- Features a Base-8 fiber configuration optimized for parallel single mode optics.
- Constructed with high-performance G.657.A2 bend-insensitive single mode fiber.
- Yellow OFNP/LSZH jacket provides clear identification and meets safety standards.
- Engineered with Type B polarity for direct transceiver-to-transceiver connections.
- Durable 3.0mm cable diameter is ideal for structured cabling pathways.
- 100% factory-terminated and tested to ensure reliable, high-speed performance.
Applications
This cable is purpose-built for creating a direct link between two parallel optic transceivers operating over single mode fiber. The Male MTP® connectors plug directly into the Female MPO/MTP® ports on modules like QSFP28-DR4 or QSFP-DD-DR4. It is the go-to solution for connecting switches, routers, and servers at speeds of 40G, 100G, and even 400G (e.g., 400G-DR4) within the data center.

Cross-Platform Compatibility
This cable enables a direct link between two 4-lane single mode transceivers. Its Male connectors fit into the transceivers’ Female ports, while the Type B polarity performs a “crossover.” This flips the fiber positions end-to-end, correctly aligning the four transmit (Tx) lanes from the first transceiver to the four receive (Rx) lanes on the second, establishing a functional data link instantly.
| Transceiver 1 (Tx Lanes) | Cable Pin Mapping | Transceiver 2 (Rx Lanes) |
|---|---|---|
| Pin 1 (Tx1) | ↔ | Pin 12 (Rx1) |
| Pin 2 (Tx2) | ↔ | Pin 11 (Rx2) |
| Pin 3 (Tx3) | ↔ | Pin 10 (Rx3) |
| Pin 4 (Tx4) | ↔ | Pin 9 (Rx4) |
FAQ (Technical & Product Questions)
1. What is the primary use case for this Male-to-Male Base-8 SMF cable?
This cable is designed for a direct equipment-to-equipment connection between two parallel single mode transceivers, such as QSFP28-DR4 (100G) or QSFP-DD-DR4 (400G). The Male connectors plug straight into the transceiver MPO ports to form a complete link.
2. Why use Base-8 for single mode applications?
Modern transceivers like DR4 and PSM4 use 8 fibers (4 transmit, 4 receive) for parallel transmission. A Base-8 cable perfectly matches this requirement, providing the most efficient cabling solution by ensuring all fibers are used and eliminating the need for more complex 12-fiber conversions.
3. What are the benefits of G.657.A2 fiber?
G.657.A2 is a bend-insensitive single mode fiber. It can handle a much tighter bend radius than standard G.652.D fiber without significant signal loss. This makes it ideal for high-density patching inside racks and cabinets where cables may be tightly managed.
4. Why is Type B polarity required for this connection?
Type B polarity creates a fiber “crossover” (e.g., pin 1 to pin 12). This is essential for a direct connection between two identical transceivers, as it ensures the transmitter on one end correctly sends data to the receiver on the opposite end, and vice-versa, for all four data lanes.
5. Can I use this for a 400G-DR4 connection?
Yes. A 400G-DR4 transceiver also uses a Base-8 MPO interface with 4 parallel lanes over single mode fiber. This cable is fully compatible and provides the necessary physical connection for establishing a 400G link between two DR4 transceivers.
