1-Channel Single Fiber CWDM OADM Overview
The SCAD-1 is a passive single fiber CWDM optical add/drop multiplexer (OADM) that adds and drops one CWDM wavelength pair on the East and West line sides of a single mode fiber strand. Configurable options include mini-LGX or LGX cassette housing, one of nine CWDM wavelength pairs spanning 1271 to 1611 nm, and an optional 1310 nm monitor port available on select wavelength pairs. LC/UPC connectors are used throughout.

1 Channel Single Fiber Passive CWDM OADM Unit Description
1 Channel Single Fiber Passive CWDM OADM Unit. SCAD-1 is a member of the EDGE Optics xWDM Series product line. We designed EDGE Optics xWDM Series products to allow easy, gradual, logical, and cost-efficient expansion of network bandwidth using passive WDM technology. The main advantage of xWDM is its passive nature, requiring no power supply or cooling, offering robustness with no special micro-climate requirements, and as a passive element, carrying an MTBF of 100+ years. xWDM is fully data rate and line protocol neutral, transparent to any protocol carried on the selected CWDM wavelengths. It is simple to install and requires no configuration or maintenance. SCAD-1 is a passive two-sided (East and West) Optical Add-Drop Multiplexer (OADM) package based on Thin-Film Filter (TFF) technology, allowing extraction and addition of 1 data stream (2 wavelengths) from an ITU-T G.694.2 compatible Coarse Wavelength Division Multiplex (CWDM) link. The unit features LC/UPC connectors. SCAD-1 ships in a choice of mini-LGX or LGX cassette housing.
Insertion loss is 1.2 dB standard, 1.5 dB with the 1310 nm monitor port enabled. Isolation is 30 dB from adjacent channels and 45 dB from non-adjacent channels, with a passband ripple of 0.3 dB. Polarization dependent loss is 0.1 dB, polarization mode dispersion is 0.1 ps, directivity is 50 dB, and return loss is 45 dB. Maximum power handling is 500 mW. The device is fully passive and needs no electrical power, configuration, or maintenance.
Each unit is built to order across three options: housing (mini-LGX or LGX), wavelength pair (one of nine CWDM pairs), and a 1310 nm monitor port (yes or no). The monitor port is available on 6 of the 9 wavelength pairs. It is not offered on the 1271/1291, 1311/1331, or 1351/1371 pairs.
Operating temperature range is -5°C to 70°C, storage range is -40°C to 85°C, and humidity tolerance is 5 to 95 percent. MTBF is 1,000,000 hours. The SCAD-1 is CE and ISO certified, meets ITU-T G.694.2, and complies with RoHS.

Frequently Asked Questions
Which wavelength pair should I choose?
The SCAD-1 passes exactly one of nine CWDM wavelength pairs across the ITU-T G.694.2 grid, spaced 20 nm apart from 1271 to 1611 nm, while the remaining wavelengths pass through undisturbed on both the East and West sides. The pair selected must match the CWDM channel already assigned to the transceivers at both ends of the link, per the network's documented channel plan.
Is the 1310 nm window port available on every wavelength pair?
No. The 1310 nm window port is available on 6 of the 9 wavelength pairs. It is not offered on the 1271/1291, 1311/1331, or 1351/1371 pairs.
Does the housing choice (mini-LGX vs LGX) affect the optical specification?
No. Insertion loss, isolation, and the rest of the optical specification are set by the underlying TFF filter and are identical between the mini-LGX and LGX cassette options. Housing choice changes only the physical footprint and mounting format, not the passband, insertion loss, or isolation figures.
