Seamlessly bridge the gap between high-density backbone infrastructures and active network ports. From our advanced Wuhan Optical Valley facility, we engineer premium custom MTP/MPO to LC, SC, or MDC fanout and breakout assemblies. Designed for 40G-to-10G, 100G-to-25G, and advanced 400G/800G transceiver port-splitting layouts, we turn complex multi-fiber routing into flawless, low-loss physical connectivity.
Advanced Quality Control
100% 3D interferometer verification on the MTP/MPO base connector paired with meticulous ferrule concentricity tracking on every split LC/SC connector channel. We provide complete batch IL/RL metrics to eliminate signal distortion during multi-port transceiver migration.

Contact Us TodayBuying Guide: Choosing the Right MTP®/MPO Breakout Solution
Scaling your enterprise data center to 100G, 400G, or 800G compute architectures requires absolute port precision. Whether you are splitting a high-speed spine switch breakout port down to multiple distributed leaf line cards, or feeding high-density signals directly into server NICs, selecting the right pre-terminated fiber breakout cable matrix is critical for protecting your link loss budget.
1. MTP® vs. MPO: The Difference
While often used interchangeably across deployment orders, MTP® is a registered trademark of US Conec representing mechanical enhancements. A custom MTP breakout cable features redesigned floating ferrules and elliptical guide pins to ensure superior physical fiber face contact and lower channel insertion loss compared to a standard unbranded MPO breakout cable.
2. MTP to LC Fanout Cables
The quintessential hardware migration link. An MTP to LC breakout cable splits a single aggregated QSFP/OSFP multi-fiber port into multiple independent 10G/25G/100G LC duplex connections for server NIC arrays, substantially optimizing 1U panel rack packing density and clean fiber tracing.
3. MTP to MTP Conversion
Not all high-density breakout tails terminate in LC single fiber ends. An MTP to MTP fiber breakout array (such as 1x 24-fiber converting to 3x 8-fiber tails) allows operators to aggregate three separate 40G QSFP+ channels back into a single 120G CXP active cluster port, achieving 100% full core utilization across modern Base-8 infrastructure.
4. Base-8 vs. Base-12 Architecture
Modern high-speed 400G transceivers (such as QSFP-DD DR4) operate strictly on 8-fiber lanes. Utilizing a native Base-8 MPO to LC breakout cable ensures zero dark or wasted internal fibers, unlike legacy Base-12 links where 4 cores remain unused. WolonFiber factory specializes in exact engineering across Base-8, 12, and 24 configurations.
5. Jacket Ratings: LSZH vs OFNP
Building fire safety compliance is an absolute mandate. We extrude our custom fiber breakout cables with distinct flame-retardant composites. Specify premium OFNP (Plenum) for standard forced-airflow pathways across North America, or low-smoke halogen-free LSZH configurations for corporate European facilities.
6. Polarity & Elite Grade Loss
Standard parallel splitting configurations typically run on Type B (Reversed) polarity standards. As a direct-source OEM manufacturing factory, WolonFiber guarantees 100% multi-stage geometric interferometer screening. We strongly suggest specifying our Elite Grade (0.35dB max MTP, 0.1dB LC IL) MTP patch cables to prevent bit-error rates across compute nodes.
Frequently Asked Questions
Find quick, technical answers about our high-density MTP/MPO breakout and fanout cabling solutions.
Yes. As a direct OEM manufacturer, our MPO and breakout cables are rigorously tested to meet MSA standards. We guarantee 100% compatibility with all mainstream equipment providers, including Cisco, Arista, Juniper, Mellanox (NVIDIA), HPE, Dell EMC, Brocade, Huawei, and Fortinet.
Most 40G to 10G or 100G to 25G applications require Type B (Reversed) polarity to ensure the Tx-to-Rx link is correctly mapped. If you are unsure about your network architecture, our engineers can provide a free wiring diagram verification to secure your routing layout.
Elite Grade connectors utilize superior ferrules to achieve a maximum insertion loss of 0.35dB (typical 0.10dB). This is absolutely critical for tight-budgeted 400G and 800G networks where the optical loss headroom is extremely small.
Yes. As a direct factory, WolonFiber offers custom staggered fanouts for neat, effortless patching in high-density panels, or equal-length legs for general routing. We can fully customize the breakout length from 0.3m to 2m+ based on your specific cabinet and chassis layout.
Absolutely. Every batch of our MPO/MTP breakout assemblies undergoes 100% 3D geometry testing to strictly monitor apex offset, fiber height, and radius of curvature. Individual test reports can be supplied along with your delivery to guarantee zero-defect performance.
Because we control the entire OEM manufacturing process inside our Hubei factories, our turnaround is exceptionally rapid. Standard custom fanout configurations typically ship within 3 to 7 business days, bypassing the multi-week delays common with trading distributors.
