8CH MWDM Demux Module, 1271.5–1341.5 nm with FC/UPC Interfaces and ABS Box Package,gracyfiber

The 8CH MWDM Demux Module is a passive wavelength division component designed to separate eight optical channels from 1271.5 nm to 1341.5 nm in O-band systems. It supports a 10 nm channel spacing and is specified with insertion loss of ≤3.0 dB, ripple of ≤0.5 dB, return loss of ≥45 dB, directivity of ≥50 dB, and polarization dependent loss of ≤0.1 dB.

• Eight defined MWDM channels from 1271.5 nm to 1341.5 nm — supports wavelength separation in O-band transmission systems.
• 10 nm channel spacing — provides a structured channel plan for MWDM network design and subsystem integration.
• Insertion loss of ≤3.0 dB — helps manage optical loss from the common port to each demultiplexed channel.
• Ripple of ≤0.5 dB — helps maintain more consistent performance across the specified passband.
• Adjacent isolation >25 dB and non-adjacent isolation >35 dB — supports channel separation and reduces crosstalk between wavelengths.
• PDL of ≤0.1 dB and PMD <0.1 ps — limits polarization-related variation and dispersion effects.
• FC/UPC connectorized design with 0.9 mm white pigtails — supports installation into optical equipment and lab or field assemblies.
• 100% 3D connector end-face inspection for internal control — supports connector geometry verification before shipment.

• MWDM optical access networks
• Mobile fronthaul systems
• O-band wavelength demultiplexing
• Passive wavelength routing
• Fiber capacity expansion systems
• Optical transport equipment integration
• WDM subsystem development
• Optical test and monitoring setups

Optical performance can be tested according to the agreed specification. Key parameters are verified before shipment, including insertion loss, ripple, return loss, directivity, and channel isolation when defined in the approved inspection criteria. Test reports can be provided upon request. Customized inspection requirements can be discussed, including connector inspection, channel-by-channel verification, and reporting format.

• Defined O-band channel plan for systems using 1271.5–1341.5 nm MWDM wavelengths.
• Module-level integration format with ABS packaging, FC/UPC interfaces, and managed pigtail length.
• Configurable engineering review for channel allocation, fiber type, connector type, pigtail length, and package requirements.
• Test documentation support with agreed inspection items and available test reports upon request.
• Suitable for sample evaluation and volume planning for both pilot builds and larger project requirements.

It separates eight optical wavelengths from a common input path into individual channel outputs in an MWDM system.

The channel set is 1271.5 nm, 1281.5 nm, 1291.5 nm, 1301.5 nm, 1311.5 nm, 1321.5 nm, 1331.5 nm, and 1341.5 nm.

The current product information is for a Demux module. However, the supplied mechanical image shows a Mux label, so the final product drawing and label should be confirmed before publication or order release.

The supplied specification table indicates a channel passband of ±3 nm at -0.5 dB bandwidth. This should be confirmed against the original “PB±3dB" wording.

The current configuration uses FC/UPC connectors, 0.9 mm white loose-tube pigtails, and a note that G657A1 fiber is permitted for the current batch.

The module uses a 100 * 80 * 10 mm ABS box. The fiber length is 1.00 ±0.03 m including connectors.

Yes. Test reports can be provided upon request, based on the agreed specification and inspection items.

Please provide the operating wavelength, channel count, channel plan, fiber type, connector type, fiber length, package requirement, target optical specifications, and estimated quantity.

For a technical review or quotation, please provide the required operating wavelength, channel count, channel wavelengths, fiber type, connector type, fiber length, package requirement, target optical specifications, and estimated quantity. If port labeling, end-face inspection records, or channel-by-channel data are required, these items should also be included in the inquiry.
