SCAD-2: Configurable 2-Channel Single Fiber CWDM OADM
SCAD-2 is EDGE's manufactured 2-channel single fiber CWDM OADM (optical add/drop multiplexer) module, built to ITU-T G.694.2 with 20 nm channel spacing. It adds and drops 2 duplex CWDM channels (4 wavelengths) on each of its East and West line directions, using TFF (thin film filter) technology, and needs no electrical power or active cooling. SCAD-2 ships as a configurable build. Buyers select one of five wavelength bands (1271-1331nm, 1311-1371nm, 1391-1451nm, 1471-1531nm or 1551-1611nm) and one of two housings (mini-LGX or LGX), and can add an optional 1310nm monitor port. As a passive device, SCAD-2 adds no signal processing and is transparent to the protocol carried on each stream, so it fits standard CWDM add/drop deployments regardless of the protocol used.

2 Channels Single Fiber Passive CWDM OADM Unit Description
SCAD-2-CFG is a passive optical add-drop multiplexer built on thin film filter (TFF) technology per ITU-T G.694.2. The unit adds and drops two duplex CWDM channel pairs, four wavelengths total, on both the East and West line directions from a single unit. Configurable LGX housing, in mini-LGX Type or LGX Type, ships with LC/UPC connectors for installation into CWDM links.
Channel spacing follows ITU-T G.694.2 at 20 nm intervals, with a passband of plus or minus 6.5 nm around each center wavelength. Five configurable CWDM bands are available: 1271 to 1331 nm, 1311 to 1371 nm, 1391 to 1451 nm, 1471 to 1531 nm, and 1551 to 1611 nm, each covering one duplex channel pair. Adjacent channel isolation is rated at 30 dB and non adjacent channel isolation at 45 dB, with passband ripple held to 0.3 dB.
Base insertion loss through the passband is 1.8 dB with no monitor port fitted. An optional 1310 nm monitor port adds its own 1.0 dB tap loss and raises the main passband insertion loss to 2.1 dB when selected. Polarization dependent loss is 0.1 dB and polarization mode dispersion is 0.1 ps. Directivity is rated at 50 dB and return loss at 45 dB, with maximum power handling of 500 mW.
SCAD-2-CFG is fully passive, requiring no electrical power or active cooling, and is protocol and data rate transparent on every channel it carries. Mean time between failures is rated at 1,000,000 hours. Operating temperature spans -5 to 70 C, with storage from minus 40 to 85 C. The unit carries CE and ISO marks, meets ITU-T G.694.2, and is RoHS compliant.
Unlike EDGE's SCMD mux and demux units, which ship in matched Side A and Side B pairs, SCAD-2-CFG is built as a single two-sided unit that handles the same add and drop channels on both the East and West line directions without a matching unit at the far end.
Housing type, wavelength band, and monitor port are configured at order time to match the specific CWDM link. For configuration guidance or volume quantities, contact our sales team.
Frequently Asked Questions
Does the SCAD-2-CFG need a matching OADM unit at the far end of the link?
No. SCAD-2-CFG is a two-sided unit that adds and drops the same channels on both the East and West line directions from a single unit. This differs from EDGE's SCMD mux and demux family, which ships in matched Side A and Side B pairs for the two ends of a link.
Is the 1310 nm window port required?
No, the window port is an optional configuration selected at order time. It adds 1.0 dB of insertion loss on its own tap and raises the main passband insertion loss from 1.8 dB to 2.1 dB when selected. Skip it if in-service monitoring is not needed for the link.
What wavelength bands are available for SCAD-2-CFG?
SCAD-2-CFG is configurable across five CWDM bands: 1271 to 1331 nm, 1311 to 1371 nm, 1391 to 1451 nm, 1471 to 1531 nm, and 1551 to 1611 nm. Each band covers one duplex CWDM channel pair, spaced at 20 nm per ITU-T G.694.2.
Does SCAD-2-CFG require electrical power?
No. SCAD-2-CFG is a fully passive thin film filter device with no electrical power or active cooling requirement. It carries a rated MTBF of 1,000,000 hours.
