E2000 UPC Connector Mechanical and Optical Design Architecture

The E2000 connector (also referred to as the LSH connector in certain international specifications) is designed and manufactured in full compliance with IEC 61754-15 and TIA-604-16 international standards.Its mechanical locking mechanism utilizes a push-pull bayonet-style design, enabling smooth insertion and removal while effectively preventing accidental disconnection caused by lateral pulling forces or vibration in high-density cabling environments.

The core optical component of the E2000 connector is a high-precision 1.25 mm zirconia ceramic ferrule. FOCC employs advanced Active Core Alignment (ACA) technology, using titanium inserts to precisely align the fiber core with the mechanical axis of the ferrule. This process minimizes eccentricity-induced insertion loss and ensures highly consistent optical performance.

The multimode polishing process utilizes Ultra Physical Contact (UPC) polishing technology. By tightly controlling ferrule end-face geometry, including radius of curvature, apex offset, and fiber protrusion/recession, the connector achieves a typical insertion loss of ≤0.15 dB and a return loss of ≥35 dB.

One of the most distinctive features of the E2000 connector is its integrated automatic spring-loaded metal shutter system. When the connector is disconnected, the shutter automatically closes and provides dual protection:

• Laser Safety Protection:During active network operation, the shutter completely blocks potentially hazardous invisible laser emissions from the ferrule end face, helping protect installation and maintenance personnel from accidental retinal exposure.
• Dust and Contamination Protection:The closed metal shutter isolates the ferrule end face from airborne dust particles, moisture, and oil contaminants. This significantly reduces the risk of end-face contamination and high-power optical burning, improving long-term network reliability and connector lifespan.

Performance Characteristics of OM4 Multimode Fiber and 0.9 mm Semi-Tight Buffer

This product utilizes laser-optimized OM4 graded-index multimode fiber with a standard 50/125 μm core/cladding diameter, fully compliant with ITU-T G.651 and ISO/IEC 11801 standards.

OM4 fiber is specifically optimized for 850 nm Vertical-Cavity Surface-Emitting Laser (VCSEL) applications. At 850 nm, it provides an Effective Modal Bandwidth (EMB) of ≥4700 MHz·km, enabling transmission distances of up to:

• 550 meters at 10 Gb/s Ethernet
• 150 meters at 40 Gb/s and 100 Gb/s Ethernet backbone links

The fiber is protected by a 0.9 mm (900 μm) semi-tight buffer layer. For fusion-splicing pigtail applications, this semi-tight buffer construction offers several significant mechanical and installation advantages.

Micro-Bending Stress Isolation

The semi-tight buffer maintains a microscopic clearance between the buffer layer and the fiber coating. This design prevents external tensile, torsional, or thermal expansion stresses from being directly transferred to the optical fiber, reducing the risk of micro-bending loss.

As a result, the fiber maintains exceptionally low attenuation even when routed through tightly packed splice trays, distribution boxes, or termination enclosures.

Simplified Fiber Preparation

The semi-tight buffer material allows technicians to strip up to 100 mm of buffer coating smoothly using standard three-hole fiber stripping tools without damaging the primary coating layer.

This significantly improves splicing efficiency, reduces installation time, and minimizes the risk of fiber breakage during field termination.

Heather Violet (Magenta) Jacket Identification

According to the TIA-598-D fiber optic color-coding standard, Magenta (Heather Violet) is the designated identification color for OM4 multimode fiber systems.

This color coding enables network operators and technicians to quickly distinguish OM4 high-bandwidth infrastructure from OM3 aqua cabling and legacy OM1/OM2 orange systems, reducing the risk of incorrect patching and network performance degradation.

LSZH Jacket Material Science and Fire Safety Performance

In enclosed, high-density environments such as data centers, telecommunications rooms, and enterprise network facilities, cable fire performance is a critical safety consideration.

Traditional Polyvinyl Chloride (PVC) jackets release dense black smoke and toxic halogen-containing gases when exposed to fire or thermal decomposition. When these gases interact with moisture in the air, they form highly corrosive acids such as hydrochloric acid (HCl), which can severely damage electronic equipment, metallic connectors, and network infrastructure, resulting in secondary equipment failures and extended service interruptions.

This product utilizes a Low Smoke Zero Halogen (LSZH) thermoplastic flame-retardant jacket material throughout its construction.

Its fire-resistant and low-toxicity characteristics are achieved through the incorporation of approximately 50% inorganic metal hydroxide flame-retardant fillers, typically aluminum hydroxide (Al(OH)₃) or magnesium hydroxide (Mg(OH)₂).

During fire exposure, these compounds undergo an endothermic dehydration reaction:

2Al(OH)3→Al2O3+3H2O↑2Al(OH)_3 \rightarrow Al_2O_3 + 3H_2O \uparrow2Al(OH)3​→Al2​O3​+3H2​O↑

This reaction provides multiple fire-protection mechanisms:

• Absorbs substantial thermal energy from the combustion process.
• Lowers the local cable surface temperature.
• Releases water vapor that dilutes surrounding oxygen concentration.
• Forms a protective ceramic-like barrier layer on the cable surface.

Together, these mechanisms significantly slow flame propagation and help prevent fire spread along cable pathways, improving personnel safety, protecting critical infrastructure, and supporting compliance with modern data center fire-safety requirements.
