Overview

IEC 61753-041-2:2014 specifies minimum initial performance, test and measurement requirements for non-connectorized single-mode OTDR reflecting devices used to monitor point-to-point (PTP) and point-to-multipoint (PTMP) passive optical networks (PON) with an optical time-domain reflectometer (OTDR). It defines the criteria for categorization as Category C (controlled environment) per IEC 61753‑1:2007, covering functional definition, test methods and required severities to demonstrate compliance.

Key topics and technical requirements

• Scope and purpose: Requirements for non-connectorized OTDR reflecting devices intended for single-mode PON monitoring (PTP / PTMP).
• Device definition: An OTDR reflecting device is a wavelength-selective reflector with two ports that transmits signal wavelengths between ports while reflecting OTDR wavelengths back to the launch port.
• Device types:
  • Type A - low attenuation (examples include FBG, collimator-based thin-film filters, direct coupled TFF).
  • Type B - higher attenuation (examples include some NWBD and WDM-based implementations).
• Wavelength ranges:
  • Signal wavelength ranges: 1260–1360 nm, 1480–1500 nm, 1550–1560 nm.
  • OTDR wavelength ranges: 1620–1630 nm, 1645–1655 nm.
• Performance metrics: Includes insertion loss (Type A ≤ 0.5 dB; Type B ≤ 1.0 dB as referenced), dimensional compliance to manufacturer drawings, and sample-size rules (defined in Annex A).
• Test methods: All tests follow the IEC 61300 series (basic test and measurement procedures). Normative references list environmental and mechanical tests such as vibration, shock, cold, dry heat, damp heat, change of temperature, fiber/cable retention, high optical power, polarization and wavelength dependence assessments.
• Documentation: Fully documented test reports and evidence are required to demonstrate compliance.

Practical applications and users

• Applications: Remote fibre health monitoring, OTDR-based fault localization, live PON monitoring without disrupting customer services, integration into PTP or PTMP PON architectures using WDM, FBGs, thin-film filters or branching devices.
• Who uses this standard:
  • Fibre optic component manufacturers designing OTDR reflecting devices.
  • Network equipment vendors integrating passive OTDR monitoring elements.
  • Test laboratories and certification bodies performing compliance testing.
  • Network operators and system integrators specifying controlled‑environment PON monitoring components.

Related standards

• IEC 61753‑1:2007 (general guidance for performance categories)
• IEC 61300 series (basic test and measurement procedures)
• IEC 60793‑2‑50 (single-mode fibre product specs)
• IEC 62074‑1 (fibre optic WDM devices)

This standard is essential for ensuring reliable, repeatable OTDR monitoring in controlled-environment PON deployments and for specifying components that meet industry-recognized performance and test requirements.

with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.

1 Scope
This part of IEC 61753 contains the minimum initial performance, test and measurement
requirements and severities which a fibre optic non-connectorized OTDR reflecting device for
monitoring point to point (PTP) or point to multipoint (PTMP) passive optical networks (PON)

as meeting the requirements of category C (controlled environments), as defined in Annex A
of IEC 61753-1:2007.

(informative)
General information for OTDR reflecting device

OTDRs outside the PON’s working wavelength range are used for physical monitoring of the
network lines. Reflector devices with high reflectance may help to monitor the network lines.
Reflector devices are components with one input and one output port. Figure B.1 shows the
functional principle of such a device.
IEC  1567/14
* Transmission wavelengths shall be operable in both directions.
Figure B.1 – Functional principle of an OTDR reflecting device
The OTDR reflecting devices are used inside the optical network for reflecting the OTDR
signals back to the central office (CO) without disturbances to the traffic signals. The reflector
can be based on different technical solutions:
– Patch cord or pigtail with one optical connector with wavelength selective coating at the
front surface (Figure B.2). The connector is shown as it provides support for the
wavelength selective coating.
