Key Technical Features
The ELF-5800 is designed to offer an optimal balance between functionality, portability, and accuracy:
Wavelengths: 1310 nm / 1550 nm for single-mode mode.
Dynamic range: 24 dB at 1310 nm / 22 dB at 1550 nm.
Maximum test range: up to 60 km.
Dead zone: approximately 1.2 m.
Integrated Multifunction:
• OTDR (Optical Domain Reflectometer)
• VFL (Visual Fault Locator) with 650 nm emission
• OPM (Optical Power Meter)
• OLS (Optical Light Source)
Display/User Interface: 3.5″ color display with an intuitive interface in languages such as English and French.
Battery and Autonomy: Powered by a 4000 mAh rechargeable battery (approximately 8 hours of continuous use).
Weight and Dimensions: Lightweight (around 350 g) for easy field use.
Optical Connectors: Compatible with SC/APC connectors (or other variants) depending on the version/customer.
Key Features
: OTDR Measurement: The ELF-5800 allows for the characterization of fiber optic links, locating events (splices, connectors, faults, losses) and measuring partial attenuation.
VFL (Visual Fault Locator): With visible light emission at 650 nm, it allows for the detection of breaks, cracks, or micro-bends in the fiber optic cable.
Optical Power Measurement (OPM): Typical range from -70 dBm to +10 dBm, ideal for verifying optical levels in active links.
Optical Light Source (OLS): For performing attenuation (insertion/loss) tests with a stable optical reference signal.
Memory and Storage: Internal storage for saving traces and results in the field (standard capacity, typically in gigabytes).
Use in networks with PON splitters: Although the device does not reach extreme ranges, it is viable for FTTH access links with PLC-type splitters up to 1:64 (depending on link conditions) — with the usual limitations of cascade losses.
Robustness: Rugged design for field use, with protection against vibration, dust, and environmental conditions.
Competitive Advantages and Target Markets
The ELF-5800 offers a highly competitive solution for installers, telecommunications companies, network integrators, and maintenance technicians who need to:
reduce the number of instruments they carry into the field (by integrating four functions into one),
accelerate testing and diagnostics,
have a lightweight and portable device with sufficient battery life for a full workday,
and obtain reliable measurements on links up to tens of kilometers long.
This device complements Elfcam's range of test equipment, offering an alternative for FTTH scenarios or optical access networks where ultra-long ranges are not required.
