The single-fiber CWDM filter units can be mounted stand-alone in the TM-101/-102 chassis or in the larger TM-301 or TM-3000 chassis where it can be combined with other CWDM or DWDM Traffic Units.

The Transmode single-fiber configuration provides a higher degree of networking flexibility since each single-fiber within the fiber-pair can be used independently. This configuration is particularly effective when building bus and ring networks since the optical filters can be placed on either of the single-fibers to provide best transmission performance and/or to enable hitless future upgrades. One of the single-fibers can as an alternative be used for 10G connections using DWDM channels. The figure above shows an example where one single-fibre is used for a 4ch bus network, and the second single-fiber is used for an 8ch point-to-point connection.
A bi-directional connection on a single-fiber is created using two separate wavelengths, one for up-link and one for down-link. The following wavelength pairs are used to create a bi-directional connection;
Upper wavelength band: 1470/1490, 1510/1530, 1550/1570, 1590/1610nmLower wavelength band: 1270/1290, 1310/1330, 1350/1410, 1430/1450nm
The lower wavelength band does not use wavelengths 1370 and 1390nm. This is done to avoid the "water-peak" of standard G.652 fibres and thus open for using all 16 channels also on longer links. The intrinsic higher fiber attenuation in the lower wavelength band will however still limit the bridgeable distance and must be taken into account when designing thenetwork.

The figure shows the two MDU's that operate in the upper wavelength band. Note the direction of the wavelengths:

1ch Add/Drop units are provided in both upper and lower wavelength band; One unit type has a single 1ch AD-filter and another has two 1ch AD-filters connected back-to-back as shown in the figure.
The 2x 1chAD-filters provide a more compact solution for bus networks where an add/drop in both east and west direction is needed.
All AD-filters are half-sized units.

To MDUC4-TA/1470 To MDUC4-TB/1470
To enable up to 8 bidirectional channels on a single-fibre, a MDU-pair for the lower wavelength band can be used. The index "E" indicates that they have an extension port that can be connected to the MDU's in the upper wavelength band and thus giving a 4+4 channel system on a single-fibre.
MDUC4-EA/1270 Transmits 1270, 1310, 1350, 1430nmMDUC4-EB/1270 Transmits 1290, 1330, 1410, 1450nm
The MDUC4-EA/1270 can be combined with a MDUC4-TA/1470 and the MDUC4-EB/1270 can be combined with a MDUC4-TB/1470 to form a 8ch connection. All MDU's are half-sized units.

Misc Data
The two upper tables shows the end-to-end losses between different units. When designing links using the wavelength in the lower band, ensure to use the correct fibre attenuation values.
As can be seen in the tables, the wavelengths in the lower band have less attenuation through the MDU's compared to the wavelengths in the high band. This is to compensate for the higher fiber attenuation and thus give an overall lower loss.
The fiber attenuation in the low wavelangth band will be the limiting factor and will vary between different fibers. As a consequence, some of the 16 wavelengths cannot be used.
