O-Band WDM Multiplexer – LWDM, MWDM & DWDM, 2–16CH
GracyFiber O-Band WDM Multiplexer is a multi-band wavelength-division multiplexing solution covering the 1260–1360 nm optical window. The product family supports LWDM, MWDM, and DWDM wavelength configurations and incorporates a 1550 nm monitor port covering 1525–1565 nm.
The supplied documentation specifically identifies low insertion loss, high isolation, high optical performance, and up to 16-channel MWDM design as product characteristics.
These applications are explicitly listed in the supplied product documentation.
An O-Band WDM Multiplexer combines or separates multiple optical wavelengths within the O-band transmission window. The supplied GracyFiber product family operates across 1260–1360 nm and supports LWDM, MWDM, and DWDM wavelength configurations.
The main difference in the supplied product family is the wavelength grid and channel passband.
LWDM uses a specific set of O-band center wavelengths with a listed passband of ±1.15 nm. MWDM uses another wavelength grid with a listed passband of ±2.5 nm. The O-band DWDM version uses much closer wavelength spacing and provides passbands of ±0.2 nm for 200 GHz and ±0.52 nm for 400 GHz.
The specification table lists:
2CH / 4CH / 8CH / 12CH / 16CH
However, exact availability for each LWDM, MWDM, and DWDM wavelength grid should be confirmed when ordering.
Yes. The supplied specification lists a 1550 nm monitor port covering 1525–1565 nm.
The relationship between this monitor port and the separate “1310 Port” parameter in the spreadsheet requires confirmation before publication.
The supplied specification lists LC/UPC or customized connectors, 250 μm / 900 μm fiber configurations, and several mechanical package dimensions.
For other configurations, please provide GracyFiber with your required wavelength plan, channel count, fiber, connector, package, and target optical specifications.

The GracyFiber O-Band WDM Multiplexer is designed for optical systems that require several wavelength channels to operate across the 1260–1360 nm window while sharing common fiber infrastructure.
The product family combines three wavelength-management approaches within the same general platform: LWDM, MWDM, and O-band DWDM. Each version uses a different wavelength grid and passband, enabling optical engineers to select a configuration according to required channel density, wavelength plan, and system architecture.
For LWDM, the supplied specification defines twelve center wavelengths from 1269.23 nm to 1318.35 nm with a ±1.15 nm passband. The MWDM specification lists wavelengths from 1271.5 nm to 1341.5 nm with ±2.5 nm passband. The DWDM configuration provides a denser set of wavelengths from 1295.56 nm to 1312.58 nm, with passband options associated with 200 GHz and 400 GHz configurations.
The system also includes a listed 1550 nm monitoring port covering 1525–1565 nm, allowing an additional wavelength region to be incorporated into the module architecture.
Optical insertion loss varies with channel count, from a listed maximum of 1.3 dB for 2CH to 4.5 dB for 16CH, while adjacent and non-adjacent isolation are specified at ≥30 dB and ≥40 dB respectively.
The supplied documentation positions the series for 5G, data-center, access-network, transceiver-test, reliability-monitoring, and debugging applications.
In 800G optical transceiver development and production testing, individual optical lanes may need to be separated for Tx/Rx measurement, characterization, or fault analysis.
The O-Band WDM Multiplexer provides wavelength-selective separation or combination for multi-wavelength optical interfaces. The supplied documentation specifically identifies Per-Lane 800G Tx/Rx Testing as an application.
5G fronthaul links can use multiple optical wavelengths to increase fiber utilization between network elements.
The available LWDM / MWDM / DWDM wavelength configurations allow multiple O-band channels to share existing fiber infrastructure, while the documentation explicitly identifies 5G Fronthaul Networks as a target application.
Optical modules undergoing burn-in, HTOL, or reliability validation may require multiple wavelength channels to be monitored and separated during testing.
The supplied documentation lists Burn-in, HTOL & Reliability Monitoring and Rapid Failure Analysis & Debug as intended applications.
GracyFiber supplies passive wavelength-management and fiber-optic components for optical communication, data-center interconnect, access networks, photonics, and optical testing.
