INTRODUCTION

2 Functional DescriptionThe MDU 8ch units are all-optical devices with both an 8ch Mux and an 8ch DeMux on thesame board. All units have an extension port enabling the units to be cascaded.

Fig. 1 Generic block diagram of the MDU units

The MDU’s are divided into two groups:• 5 units operating at the even 50GHz channels (MDU8EExxx-yyy). These units match the

wavelengths covered by the MDU40/50G-EVEN.• 5 units operating at the odd 50GHz channels (MDU8EOzzzz-wwww). These units match

the wavelengths covered by the MDU40/50G-ODD.MDU units within the same group can be combined in any order up to a 40ch configuration.Both groups can be combined via an optical interleaver (OIU-C-50/100) to form an 80chconfiguration.

One important feature is that the MDUs operate at 100GHz spacing which enables pluggableoptics to be used on the MDU8EE units, i.e. SFPs and XFPs. The odd 50GHz channels canbe covered via Traffic units having a fixed/tunable line interface, or XFP-based units support-ing the tunable XFP TRX100090/TC.

The MDU units are passive units, i.e. contains no microprocessors or other electrical compo-nents apart from a small memory circuit to provide remote inventory data.

All MDU8-versions are for fiber-pair configurations and can be combined with optical ampli-fiers to extend the transmission distances without electrical regeneration.

The MDU8EExxx-yyy units can be used in 40ch configurations together with other passiveunits. The figure below shows all available units that can be used in 40ch configurations.

FUNCTIONAL DESCRIPTION

TD-MDU8-50G Rev C | 2014-11-02 3 (14)


Fig. 2 40ch configuration units

A 40ch setup can be established using a 40ch MDU (MDU40/50G-EVEN) or by combining five8ch MDU units (MDU8EExxx-yyy). These 8ch MDU units match the wavelengths covered bythe MDU40/50G-EVEN and BSU1x5/EVEN50G.

The choice between a 40ch MDU and multiple 8ch MDU units in a terminal node is a balancebetween initial cost, end cost and needed physical space in the card cages.

The MDU8EOzzzz-wwww units are typically used in combination with the 40ch configurationcomponents to provide a 50GHz-spaced 80ch configuration. The optical interleaver (OUI-C-50/100) is required to combine the Even and Odd 50GHz channels.

Fig. 3 Components to create 80ch configurations

2.1 Placement in Card CageThe MDU Units are full-sized units. See Dimensioning Guidelines or the respective TechnicalDescriptions for the chassis for information on what slots that support these units.


TD-MDU8-50G Rev C | 2014-11-02 5 (14)


3 ApplicationsSee also Dimensioning Guidelines within the System Manual for more application examples.

3.1 40ch end node using 8ch MDU unitsAll MDU8 units have an extension port enabling them to be combined in any order. Adding aMDU via the extension port will not affect active traffic.

Fig. 4 40ch configuration using MDU8EExxx-yyy units

In Fig. 4 40ch configuration using MDU8EExxx-yyy units each MDU unit is combined with an8ch VOA (VOA-8CH/II) to enable power balancing. See Technical Description “2-port OpticalChannel Monitor unit (OCM/2P R1)” in the System Manual for more details on the automaticpower balancing feature.

APPLICATIONS

TD-MDU8-50G Rev C | 2014-11-02 6 (14)


3.2 40ch BSU and MDU configuration

Fig. 5 40ch example configuration

Fig. 5 40ch example configuration shows an example of how the Band splitter unit (BSU1x5/EVEN50G), MDU and AD units (AD4/50G-Exxx) can be combined in a network.

In Node A all eight channels are add/dropped by connecting MDU8EExxx-yyy units to the cor-responding ports of the BSU1X5/EVEN50G unit.

In Node B the AD4/50G-E/xxx units are used to add/drop 4 channels of the same band.

In both Node A and B all other channels are glassed through.

In Node C a stand-alone BSU splits up the band into five different directions where the corre-sponding MDU8EExxx-yyy units are used to terminate each optical path.

As shown, all 40 channels are easily available in Node A and B. To provide similar full accessusing MDU units, two MDU40/50G-EVEN units would be required in both Node A and B.

APPLICATIONS

TD-MDU8-50G Rev C | 2014-11-02 7 (14)


3.3 40ch and 8ch MDU ConfigurationFig. 6 8ch banded network example shows another alternative network solution where the 8chMDU units are connected to provide 8ch add/drop per site. Note how the extension ports areconnected so that all other channels are glassed through.

4 Wavelength SetupThe tables below show the covered wavelengths for all passive components operating at theeven 50GHz (i.e. 100GHz) grid. Note that pass-band is 100GHz for both Odd and Even MDUunits. They are just shifted 50GHz (see Fig. 7 Channel spacing). None of the MDU-units canthus be used directly on an 80ch setup. In an 80ch configuration, an OIU is needed to sepa-rate the odd and even bands before any of the MDU units can be inserted.

The MDU’s are used in the traditional way i.e. utilizing both fibers in the fiber-pair. One fortransmit and one for receive.

5 Management

5.1 Board dataAll boards/units within a XTM Series Network Element have unit related information stored innon-volatile memory banks. This information is stored at production and is required for admin-istration and start-up of the boards.

The information is divided into three main groups:• Environmental data - Contains data, which is read and used without knowledge of produc-

tion data version.• Generic board data - Contains administrative data, which is included on all boards, both ac-

tive and passive.• Specific board data - Data needed for proper board operation.

5.2 AlarmsEven though the MDU-units are passive devices, alarms can be generated from the units. Allpassive units (e.g. Add/drop units, Mux/DeMux units) contain no electrical functionality andthe alarms generated are few:• Vital information missing: Information in the board data memory bank that is vital to manage

the unit is missing. This alarm may require board replacement.• Non-vital information missing: Information in the board data memory bank that is not vital to

manage the unit is missing.• Board missing: The Control Unit can no longer detect the presence of the unit.See System Manual Volume C, Operation & Maintenance for further details.

5.3 Remote InventoryAn on-board EE-PROM enables remote extraction of inventory data and board data. This cir-cuit is the only active component on the unit.

The inventory information provided is:• Unit name.• Unit HW Product number.• HW revision.• Unit serial number.
