1. Product Overview

The MPO/MTP to 8x LC/UPC OS2 Breakout Cable (also known as a Harness or Fan-out cable) is engineered to connect MPO-based infrastructure to LC-based hardware. Utilizing OS2 9/125μm Single-Mode fiber, it is ideal for high-speed data center links, telecommunications, and enterprise networks. This 8-core configuration is specifically optimized for transceivers that utilize 8 fibers for parallel transmission (e.g., QSFP+ to 4x SFP+).

Product Applications

The MPO-to-8xLC OS2 breakout cable is a strategic component for modern high-bandwidth architectures:

1. 40G/100G to 10G/25G Port Breakout

This is the most common application in data centers. It allows a single QSFP+ (40G) or QSFP28 (100G) switch port to be broken out into four separate 10G (SFP+) or 25G (SFP28) ports. The 8-fiber MPO carries 4 lanes of transmit and 4 lanes of receive, which are distributed to the LC duplex pairs on the servers or secondary switches.

2. High-Density Patch Panel Distribution

In structured cabling environments, these cables connect the rear MPO ports of a patch panel to the front-facing LC ports of active equipment. This "Plug-and-Play" approach significantly reduces installation time and eliminates the risk of field-termination errors.

3. Spine-Leaf Architecture

In a Spine-Leaf network topology, this cable serves as the link between the high-capacity Spine switches (often MPO-based) and the Leaf switches or Network Interface Cards (NICs) that utilize LC interfaces. This maximizes port utilization and allows for a scalable, modular network growth.

4. Storage Area Networks (SAN)

Used in enterprise storage environments to connect director-class switches to individual storage arrays. The OS2 Single-Mode fiber provides the low attenuation and high bandwidth necessary for long-distance storage replication and low-latency data access.

5. Efficient Airflow and Cable Management

By consolidating eight fibers into a single small-diameter trunk (typically 3.0mm) before the fan-out, this cable reduces physical obstruction in front of cooling fans. This is critical for maintaining thermal efficiency in high-performance computing (HPC) racks.

Professional Recommendation:

For Single-Mode applications, we recommend utilizing MPO APC (Angled) connectors on the trunk side to minimize back-reflection, even if the LC end-face is UPC (Flat). This ensures the best possible signal-to-noise ratio for high-bit-rate transmissions.
