E2000 Connector: Technical Specifications & Standards
E2000 Connector: Technical Specifications, Standards and Performance Values Overview
The E2000 specifications, E2000 standard, E2000 technical data define one of the most robust fibre optic connectors with 2.5mm ferrule, automatic dust shutter and push-pull mechanism to IEC 61754-15. The E2000 connector achieves insertion loss of < 0.25 dB and return loss of > 60 dB (APC), making it the preferred choice for demanding FTTH projects and data centres. With a guaranteed lifespan of at least 1,000 mating cycles and a temperature range of -40°C to +85°C, it meets the highest requirements in professional fibre optic deployment.
Core Technical Specifications of the E2000 Connector to IEC 61754-15
The E2000 standard is based on the international specification IEC 61754-15, which defines precise geometric dimensions and optical performance requirements. The connector uses a fully ceramic ferrule with 2.5mm diameter, which is significantly more robust than the 1.25mm LC ferrule. This larger form factor enables more stable fibre guidance and substantially reduces mechanical stress during field termination.
The push-pull coupling system operates spring-loaded along the optical axis and ensures constant contact force of 7.8 Newton. The automatic metal shutter opens only during mating and protects the ferrule from contamination — a decisive advantage over conventional connector systems.
- Ferrule diameter: 2.5mm (fully ceramic)
- Coupling force: 7.8 N (spring-loaded)
- Tensile relief: up to 100 N (depends on cable type)
- Housing material: PBT with UL94-V0 fire rating
- Colour coding: Green for APC, blue for PC version
Optical Performance Values and Attenuation Specifications
The E2000 technical data show impressive optical performance values specified to DIN EN 61755-3-2 Grade B. For singlemode applications with APC polish, the connector achieves typical insertion loss of only 0.12 dB on average.
| Parameter | PC Version | APC Version (8°) |
|---|---|---|
| Insertion Loss (typ.) | < 0.20 dB | < 0.12 dB |
| Insertion Loss (max.) | < 0.30 dB | < 0.25 dB |
| Return Loss | > 50 dB | > 60 dB |
| Repeatability | ± 0.1 dB | ± 0.1 dB |
These values position the E2000 connector in the top performance class for FTTH networks and data centre cabling. High return loss is particularly critical for WDM systems and PON architectures, where reflections can degrade signal quality.
Mechanical Durability and Environmental Specifications
The mechanical E2000 specifications guarantee at least 1,000 mating cycles without performance degradation exceeding 0.2 dB. This exceptional long-term stability makes the connector ideal for frequently re-patched distribution fields in data centres and public networks.
The operating temperature range of -40°C to +85°C enables use in extreme environments, from unheated outdoor distribution points to high-temperature industrial settings. Storage temperature extends to -40°C to +85°C, simplifying inventory management.
- Mating cycles: min. 1,000 without degradation
- Operating temperature: -40°C to +85°C
- Relative humidity: up to 95% non-condensing
- Vibration resistance: IEC 61300-2-1 compliant
- Salt spray test: 96 hours to IEC 61300-2-26

Fibre Compatibility and Cable Types to E2000 Standard
The E2000 technical data support all common fibre types to ITU-T standards. The connector is particularly optimised for modern G.657.A1/A2 bend-insensitive fibres, which enable a minimum bend radius of only 7.5mm (A2).
For cable termination, the E2000 connector supports diameters of 0.9mm to 3.0mm, providing maximum flexibility in cable selection. The tensile relief is optimised for aramid yarn and glass rovings, making the connector particularly suitable for robust outdoor cables.
| Fibre Type | Bend Radius | Application |
|---|---|---|
| G.652.D | 30mm | Standard Singlemode |
| G.657.A1 | 10mm | FTTH in-building |
| G.657.A2 | 7.5mm | Micro-duct deployment |
| OM3/OM4 | 30mm | Multimode data centres |
Installation Guidelines and Commissioning Requirements
Installation of E2000 connectors requires precise workmanship, but is significantly simpler than SC connectors thanks to the push-pull mechanism. The E2000 specifications require maximum end-face geometry of 50μm radius on the ferrule, easily achievable with modern splice equipment.
For field termination, pre-terminated pigtails with factory-polished connectors are recommended. These guarantee compliance with optical specifications and reduce installation time by up to 60 per cent compared to on-site polishing.
- Cleaning: Always with IPA 99% and lint-free cloths
- Inspection: Video microscope with min. 200x magnification
- Splice loss: Typically < 0.05 dB for fusion
- Heat shrink tubing: 45mm or 60mm length
- Working temperature: +5°C to +40°C for optimal results
Integration in Modular Splice Systems
E2000 connectors are optimally designed for high-density splice modules. In 1RU systems, up to 96 fibres can be terminated with E2000 connectors — twice as many as standard solutions. This packing density makes E2000 the first choice for space-critical installations.
Modular design enables replacement of individual adapter plates without service interruption. The automatic dust shutter also eliminates time-consuming cleaning of unused ports, reducing maintenance time by up to 40 per cent.
Standards Compliance and Certifications
The E2000 standard IEC 61754-15 defines not only mechanical dimensions but also test procedures to IEC 61300 series. All E2000 components must pass these tests to ensure interoperability between different manufacturers.
- IEC 61754-15: Base standard for LSH connectors
- IEC 61755-3-2: Optical interfaces Grade B
- IEC 61300-2-x: Environmental and mechanical tests
- IEC 61753-1: Performance standard for singlemode
- RoHS/REACH: Compliant for EU market
Cost-Effectiveness and Total Cost of Ownership
Although E2000 connectors cost about 15-25 per cent more than LC connectors, the total cost analysis over 15 years shows clear advantages. Through reduced failure rates and lower maintenance effort, the additional cost is recouped within 3-4 years.
A municipal network operator with 10,000 connectors saves approximately €8,500 annually in maintenance costs with E2000 connectors. The automatic dust shutter prevents costly cleaning calls and substantially reduces fault-related technician visits.
Practical Applications in German FTTH Deployment
With over 2.5 million new fibre optic connections annually in Germany, demands for robust connector systems continue to rise. E2000 connectors prove their value in public networks where different service providers access the same infrastructure.
