Overview

IEC 61753-086-2:2009 is an International Electrotechnical Commission (IEC) performance standard for non-connectorized single‑mode, bidirectional WWDM devices used in passive optical networks (PON). It specifies the minimum initial performance, test and measurement requirements and severities that a fibre‑optic pigtailed device carrying 1 490 / 1 550 nm downstream and 1 310 nm upstream signals must satisfy to be classified as category C (controlled environments) under IEC 61753-1. Annex B provides functional information on these WWDM PON devices and Annex A defines sample sizes for testing.

Key topics and technical requirements

The standard concentrates on testable performance parameters and environmental conditions for WWDM PON components:

• Device type: non-connectorized, pigtailed, single‑mode, bidirectional WWDM for PON (1490/1550 nm downstream, 1310 nm upstream).
• Environmental category: Category C (controlled environments) - requirements apply where the device is used in controlled indoor settings.
• Test methods: referenced to the IEC 61300 series; fibres per IEC 60793‑2‑50.
• Measured parameters and example requirements:
  • Attenuation: ≤ 0.8 dB (measurement uncertainty ±0.1 dB).
  • Total channel isolation: ≥ 18 dB (between 1 480–1 500 nm and 1 550–1 560 nm); ≥ 30 dB (between 1 260–1 360 nm and 1 550–1 560 nm).
  • Directivity: ≥ 50 dB (Grade U).
  • Return loss: ≥ 50 dB (Grade U).
  • Polarization dependent loss (PDL): ≤ 0.2 dB (measurement uncertainty ±0.05 dB).
  • Optical power handling / damage threshold: specified test up to 300 mW total across wavelength bands, with staged increments and verification of attenuation/isolation/return-loss limits after exposure.
• Environmental tests include cold, dry heat, damp heat, change of temperature and mechanical tests per IEC 61300 parts. Test reports and supporting evidence are required.

Applications

IEC 61753-086-2:2009 is directly applicable to:

• Manufacturers and designers of WWDM PON passive components (splitters, filters, mux/demux elements) that are pigtailed and non‑connectorized.
• Test laboratories performing qualification, acceptance and factory tests for WWDM devices intended for controlled indoor installations.
• Telecommunication equipment vendors and PON system integrators specifying component performance for FTTH/FTTP networks that use bidirectional WWDM signaling (1490/1550 nm downstream, 1310 nm upstream).

Who should use this standard

• Component manufacturers for product design and quality control.
• R&D and compliance engineers validating PON WWDM modules.
• Procurement and specification writers in telecom operators and system integrators demanding category C performance.
• Test houses and certification bodies reporting compliance.

Related standards

• IEC 61753-1 (general guidance and category definitions)
• IEC 61300 series (basic test and measurement procedures)
• IEC 60793-2-50 (single‑mode fibre specifications)

Keywords: IEC 61753-086-2:2009, category C (controlled environments), WWDM, PON, 1490/1550 nm downstream, 1310 nm upstream, pigtailed WWDM devices.

3 Test
Unless otherwise specified, all test methods are in accordance with the relevant part of
IEC 61300 series.
Each test defines the number of samples to be evaluated. The samples used for each test are
intended to be previously unstressed new samples but may also be selected from previously
used samples if desired. The samples shall be terminated onto single-mode fibres as per
IEC 60793-2-50, Type B 1.1, in either coated fibres (primary and secondary) or reinforced
cable format. All measurements shall be carried out at normal room conditions, unless
otherwise stated.
All tests shall be carried out over the optical wavelength bands of 1 260 nm to 1 360 nm,
1 480 nm to 1 500 nm, and 1 550 nm to 1 560 nm, unless otherwise specified.
NOTE 1 310 nm, 1 490 nm and 1 550 nm are the peak or centre wavelengths, stated for the bands 1 260 nm to
1 360 nm, 1 480 nm to 1 500 nm and 1 550 nm to 1 560 nm.

(informative)
General information for 1 490 / 1 550 nm downstream
and 1 310 nm upstream PON WWDM devices
The 1 490 / 1 550 nm downstream and 1 310 nm upstream PON WWDM devices are used
inside the PON for facilitating the transport of downstream traffic and the separate analogue
radio frequency (RF) overlaid video (CATV) signal from the central office (CO) optical line
terminal (OLT) with the upstream one from the optical network unit (ONU) installed at the
premises. They also can be used to combine and separate the downstream and upstream
traffic at the customer ONU.
They multiplex and demultiplex the voice, data and CATV:
– 1 310 nm channel for Data/Voice upstream;
– 1 490 nm channel for Data/Voice downstream;
– 1 550 nm channel for CATV.
