General Specifications
CWDM Wavelengths
Defined by the ITU-T G.694.2, CWDM covers the wavelengths from 1270nm to 1610nm within 20nm channel spacing.
Color Coding for CWDM
For CWDM systems an industry standard color coding scheme is used. Color coded ports is designed to match the latches of CWDM transceivers for simplifying the installation.
Water Peak
For G.652 and G.694.2 optical fiber, the water peak occurs at 1383 ± 3nm within the telecommunication spectrum 1260 – 1625nm. Attenuation at and near the water peak can exceed 2 dB/km, so it is common practice to avoid 1390nm and 1410nm channels.

Dual Fiber Applications
Dual fiber CWDM OADM adds and drops optical signals of same wavelengths into two fibers, while letting the rest of the wavelengths bypass to the needed destination. The CWDM transceiver connected to CWDM OADM should have the same wavelength as the client port.
Take 1ch 1470-1490nm CWDM OADM as an example, the wavelength of the transceiver mainly based on the transmit wavelength of the client port on the CWDM OADM.

Single Fiber Applications
In single fiber applications, CWDM OADM adds and drops optical signals of different wavelengths into a fiber in the opposite direction. It utilizes a single fiber for both adding and droping, which reduces overall costs, and increases the capacity of the fiber.

II. Transmission Direction

For adding/dropping CWDM channels across sites, we categorize our CWDM OADM in two groups: single-sided (East or West) and dual-sided (East and West).
If CWDM OADM adds/drops the wavelengths in one side on fiber network, it is the East or West module; On contrary, it is the East and West module.
East or West
The single-sided OADM removes one channel from the network in one direction and sends it to a local interface. The remaining channels are passed straight through to other nodes along the network.
East and West
The dual-sided OADM removes one channel from the network in one direction and sends it to a local interface in one direction. It also allows a second local port to add the same channel back onto the network fiber in the opposite direction.

III. Special Service
Monitor Port
It is used to monitor or test the power signal, usually at a 1% ratio, 2%, 3%, 5%, etc, also available. By connecting with measurement or monitoring equipment, such as power meters, spectrum analyzer, or FMT AIU/OPD card, the signal can be inspected without interrupting the existing network.
1310nm and 1550nm Ports
The 1310nm and 1550nm are actually WDM wavelengths. Many optical transceivers, especially the CWDM and DWDM SFP/SFP+ transceiver, support long-haul transmission over these two wavelengths. By connecting with the same wavelength optical transceivers, these two ports can be used to add 1310nm or 1550nm wavelengths into existing WDM networks.
PS: If 1310nm port is added, the following CWDM wavelengths can't be added: 1270nm, 1290nm, 1310nm, 1330nm and 1350nm;If 1550nm port is added, the following CWDM wavelengths can't be added: 1510nm, 1530nm, 1550nm, 1570nm and 1590nm.
