Custom OM4 MTP®-8 to 4x LC UPC Harness Cable, Staggered Breakout Legs
-
Smart Staggered Design: Specifically engineered with staggered LC breakout lengths to perfectly match your switch port pitch, eliminating cable slack and rack clutter.
-
High-Density Migration: 8-Fiber OM4 multimode cable designed to flawlessly aggregate four 10G/25G LC duplex ports into a single 40G/100G MTP®-8 interface.
-
Premium Connectors: Utilizes US Conec MTP® connectors with an optimal 0.35dB Low Insertion Loss (IL) for maximum network performance.
-
Factory Customization: As a direct manufacturer, we offer full customization on total cable length, stagger intervals (e.g., 2cm, 5cm drops), and outer jacket ratings (LSZH, OFNP, OFNR).
Product Overview
The Custom OM4 MTP-8 to 4x LC UPC Harness with Staggered Breakout Legs is the ultimate solution for high-density data center environments. Unlike standard breakout cables with equal-length legs that create messy, hard-to-manage cable loops in front of equipment, our staggered harness is precision-manufactured to cascade perfectly across your specific switch port layout.
This 8-fiber MTP® to LC breakout cable is designed for seamless migration from duplex-based applications (10G/25G Ethernet) to parallel optics-based networks (40G/100G Ethernet). By connecting an MTP-8 transceiver (such as a 40GBASE-SR4 or 100GBASE-SR4) to four discrete LC duplex transceivers, it maximizes space efficiency while ensuring verified optical performance and reliability.
Key Features
-
Custom Staggered Geometry: Tell us your switch model or port spacing, and we will manufacture the LC legs with exact staggered drops for a flawless, "waterfall-free" routing experience.
-
Bend-Insensitive Fiber: Constructed with advanced bend-insensitive multimode fiber (BIMF) featuring a 7.5mm minimum bend radius, preventing signal loss in tight routing spaces.
-
Base-8 Connectivity: Utilizes only 8 fibers, ensuring 100% fiber utilization for SR4 transceivers (eliminating the 33% dark fiber waste found in legacy Base-12 cables).
-
Rigorous Factory Testing: Every harness assembly is factory terminated and 100% optically tested for insertion loss and return loss to deliver improved network integrity.

Application Scenarios
Our staggered MTP-8 to LC harnesses are highly recommended for the following environments:
-
Top-of-Rack (ToR) to Server Patching: Cleanly connecting a Top-of-Rack QSFP+ switch to multiple SFP+ server adapters directly below it.
-
High-Density SAN & Data Centers: Simplifying the physical layer topology and significantly reducing the time required for MACs (Moves, Adds, and Changes).
-
40G to 10G Breakout: Splitting a single 40G QSFP+ port into four 10G SFP+ links.
-
100G to 25G Breakout: Splitting a single 100G QSFP28 port into four 25G SFP28 links.
