The module-layout and drawing pages state “Channel optional,” indicating that channel selection may be configurable.
The GracyFiber 19CH O+C-Band DWDM Module is a hybrid wavelength-management device that combines two different optical wavelength regions within one passive module.
Its channel architecture consists of eight O-band channels and eleven C-band channels connected to a common optical port. The O-band section operates with 200 GHz channel spacing, while the C-band section uses 100 GHz channel spacing. This allows two distinct wavelength grids to be integrated into one 19-channel optical assembly.
The O-band portion covers channels O284 through O298, corresponding to wavelengths from 1312.58 nm down to 1304.58 nm. The C-band portion covers C20 through C30, corresponding to 1561.42 nm down to 1553.33 nm. The channel layout drawing on page 3 shows all nineteen wavelength ports connected to a single COM interface.
Optically, the module specifies maximum COM-to-channel insertion loss of 3.60 dB, with minimum adjacent-channel isolation of 25 dB and non-adjacent isolation of 35 dB. PDL and PMD are both limited to 0.2, while directivity and return loss are specified at ≥50 dB and ≥45 dB respectively.
Mechanically, the module uses a 120 × 80 × 14 mm black aluminum housing. The supplied drawing on page 4 shows nineteen individual channel fibers plus one COM fiber, all terminated with LC/PC connectors. The fiber length is 300 ±50 mm, using 0.9 mm loose-tube G657A1 fiber.
This architecture is suitable when a system requires simultaneous access to defined O-band and C-band wavelength channels through one compact passive wavelength-routing module.
An optical system may need to transport or access wavelength channels in both the O-band and C-band while sharing a common optical path.
The 19CH module provides eight defined O-band channels and eleven defined C-band channels through a common port, enabling the two wavelength regions to be handled in one passive module.
For test setups requiring fixed channel access across two wavelength bands, the individual O-band and C-band ports can provide discrete access to each documented center wavelength.
The specified LC/PC interfaces and individually labeled channel fibers support channel-by-channel optical connection.
The product layout is marked “Channel optional,” indicating that wavelength-channel selection may be adaptable for project requirements.
Specific custom channel combinations should be confirmed before quotation.
