Each product has a warranty against defects in material and workmanship for a period of two years from the date of shipment. During the warranty period DEV Systemtechnik will, at its option, either repair or replace the product if it turns out to be defective. -
Page 4: Limitation Of Warranty
DEV Systemtechnik shall not be liable for the failure of users to comply with these requirements. Disconnect the chassis in which the optical modules are applied from any external power line before opening of the housing. -
Page 5: Product Description
Optribution® chassis user manual. Modules Description The DEV Optribution® family is a series of products for the processing of optical signals. There are available a number of Optribution® chassis which are to be equipped with optical modules. These optical modules are described in the following. -
Page 6: Optical Transmitter Modules Dev 72Xx
6 M o n ito r P o rt All optical transmitter modules are plug-in modules and cover different frequency ranges. The DEV 7231, DEV 7232, DEV 7233, DEV 7241, and the DEV 7251 are designed for the (extended) L-Band. The DEV 7238 is intended for UHF/VHF signals;... - Page 7 LNB power supply. Alternatively -or exclusively for the modules DEV 7231, DEV 7241, and DEV 7244 with Option 35 (see below)-, the LNB power supply can be switched in Local Mode via Web Interface, and in Remote Mode via SNMP, given that the Optribution®...

Page 10: Edfa Optical Amplifier Modules Dev 74X5
Selected Optribution® chassis can be equipped with EDFA optical amplifier modules DEV 74x5. The DEV 7415 is a pre-amplifier and the DEV 7425 is designed as a boost amplifier. The optical connector type is SC/APC by default, but can be ordered as FC/APC (Option 07) or as E2000 HRL (Option 08), instead. -
Page 11: Optical De-/Multiplexer Modules Dev 76Xx
In the receiver chassis this optical signal feeds a corresponding demultiplexer module -i.e. a second module-, consequently providing two (DEV 7612), four (DEV 7614), eight (DEV 7618), or nine (DEV 7618 with Option +Lambda0) optical signal outputs, which are used for the input to the optical receiver modules. -
Page 12: Redundancy Principles
User Manual DEV 7xxx Optribution® Modules Redundancy Principles Without optical link redundancy, the RF inputs of optical transmitter modules are made accessible in an Optribution® chassis via cabling options. Cabling options are used for the RF outputs of optical receiver modules as well;... - Page 13 User Manual DEV 7xxx Optribution® Modules There are four RF level monitoring [and light status indication] units per redundancy unit which can be used for the monitoring of the transmission paths. However, relevant for the autonomous switching between the main channel and the backup channel of a 1+1 redundancy is the RF level status and the light condition detection of the optical receiver channels.

"No Single Point of Failure" (NSPoF) Options To enhance the safety of 1+1 Rx redundancy configurations, the Optribution® chassis DEV 7113 equipped with single link Rx modules and 1+1 Rx redundancy options can be equipped with NSPoF options in addition. -
Page 15: N+1 Redundancy Options
Only each internal dual channel 1:2 NSPoF splitter module used inside the DEV 7113 chassis represents a passive component consisting of two locally separated 1:2 L-Band splitters on one PCB in a single mechanical housing. - Page 16 User Manual DEV 7xxx Optribution® Modules An n+1 redundancy consists of the n+1 redundancy unit in the transmitter (Tx) chassis and of the n+1 redundancy unit in the receiver (Rx) chassis. Both n+1 redundancy units comprise n main channels (optical transmitter channels or optical receiver channels) and a redundancy channel (an optical Tx or Rx channel, as well).

If gain control is available, the RGC (Redundancy path Gain Compensation) functionality becomes active in addition. Not transferred is the setting for surveillance enable.

User Manual DEV 7xxx Optribution® Modules For example, if the lower limit is -50 dBm, the factory setting for the RF threshold level is -30 dBm. The RF threshold level can be adjusted via the Web Interface or via SNMP –given that the Optribution® chassis provides these features- in a range that depends on the applied module. -
