$8.25
Directly connect 100G transceivers with this Base-12 G.657.A2 MPO/MTP® patch cord. Featuring Male-to-Male MTP® Elite connectors and highly flexible bend-insensitive single mode fiber, it is optimized for high-speed PSM4 applications in dense data center environments.
Overview
This Base-12 Male-to-Male MPO/MTP® Single Mode Patch Cord provides a direct connection between parallel optic transceivers. It features Male (pinned) MTP® Elite connectors on both ends, designed to plug directly into the Female ports on modules like QSFP+ and QSFP28. This cable is the ideal solution for establishing high-speed parallel single mode links such as 100G-PSM4 within the data center.
Built with G.657.A2 bend-insensitive single mode fiber, this cable offers exceptional resilience in tight spaces and high-density racks. This advanced fiber minimizes signal loss even with sharp bends, ensuring reliable data transmission. The 12-fiber Base-12 configuration and low-loss MTP® Elite connectors deliver the high performance and density required for next-generation network infrastructures.
Key Features
- Terminated with two Male (pinned) MTP® Elite connectors for direct transceiver-to-transceiver connections.
- Engineered with high-performance G.657.A2 bend-insensitive single mode fiber (9/125µm).
- Optimized for 100GBASE-PSM4 and other parallel single mode applications.
- Features a Base-12 fiber configuration in a single MTP® connector.
- A yellow jacket (OFNP/LSZH) clearly identifies the cable as single mode.
- Low-loss MTP® Elite connectors ensure minimal signal degradation.
- 100% factory-terminated and tested to guarantee performance upon installation.
Applications
This Male-to-Male MTP® cable is specifically designed for direct connections between two pieces of active equipment. Its primary application is connecting two parallel optics transceivers together, such as linking two 100G QSFP28-PSM4 modules in a top-of-rack or middle-of-row configuration. It is also used for connections between aggregation switches and servers equipped with MPO/MTP® interface cards.
Pinout for 100G-PSM4 (Type B Polarity)
For a direct 100G-PSM4 transceiver connection, a Type B (crossover) polarity cable is standard. This maps the transmit (Tx) channels from one transceiver to the receive (Rx) channels of the other. Although the cable has 12 fibers, PSM4 uses 8 fibers (4 for transmit, 4 for receive), leaving 4 fibers dark (unused).

Cross-Platform Compatibility
The Male (pinned) connectors on this patch cord are designed to mate directly with Female (unpinned) ports. These ports are found on parallel optics transceivers (QSFP+, QSFP28, QSFP-DD) and MPO/MTP® cassettes. Never attempt to connect this cable to another Male-pinned cable or port, as this will damage the connectors. This cable is compatible with all standard MPO interfaces and can be used with any G.652.D fiber system, as G.657.A2 is fully backward compatible.
FAQ (Technical & Product Questions)
1. What is G.657.A2 fiber and why is it important?
G.657.A2 is a class of bend-insensitive single mode fiber. It is designed to minimize signal loss when the cable is bent sharply, making it ideal for high-density environments like data center racks and enclosures where cable routing can be challenging.
2. What is the main application for this Male-to-Male MTP® cable?
Its primary application is for direct connection between two single mode parallel optic transceivers, such as linking two 100G QSFP28-PSM4 modules. The Male connectors plug directly into the Female ports on the transceivers.
3. Why is this cable listed with Type B polarity?
Type B polarity creates a “crossover” by swapping the fibers (e.g., fiber 1 connects to fiber 12). This is necessary for a direct transceiver-to-transceiver link to ensure that the transmit (Tx) pins on one side align with the receive (Rx) pins on the opposite side.
4. Can I use this single mode cable for 40GBASE-SR4 applications?
No. 40GBASE-SR4 is a multimode standard that requires OM3 or OM4 fiber (aqua or magenta jacket). This cable uses single mode fiber (yellow jacket) and is designed for single mode standards like 100G-PSM4.
5. Can I use this G.657.A2 cable with standard G.652.D single mode fiber?
Yes. G.657.A2 fiber is fully backward compatible with the standard G.652.D single mode fiber commonly used in telecommunications networks. You can connect them without issue, and the link will benefit from the G.657.A2’s superior bend performance.
