ANT-20SE Optical InterfacesMaintenance M-53.4 Installation instructions STM-16/OC-48Preparation1. Disconnect the ANT-20SE from the AC line and all test circuits.2. Heed the measures for preventing electrostatic damage.Do not remove the STM-16/OC-48 optical interface from its package until you are ready toinstall it.3. Place the ANT-20SE with its screen upwards. The side with the connectors should be facingyou.InstallationTo install the STM16/OC-48 optical interface, proceed as follows:1. Remove the “Extension slot” cover plate, two screws.2. Remove the dummy plate, four screws.3. Open the bag containing the optical interface STM-16/OC-48.The bag protects the interface module from electrostatic damage.4. Remove the interface module.5. Remove the premounted cover plate, four screws.6. Insert the interface module into the “Extension slot”.7. Screw the interface module to the chassis, four screws.8. Install the cover plate (four screws).9. Affix the laser safety warning label for a Class 3A laser product (see Fig. M-7).3.4.1 ANT-20SE operation with the STM-16/OC-48 modulesThe STM-16/OC-48 modules with their specific wavelengths can be operated only in a certainANT-20SE slot position (see Fig. M-4). The slot position depends on whether the “2488 Mbit/sJitter Analyzer/Generator” module (BN 3035/90.68) is simultaneously fitted or not.Removing the module1. Disconnect the ANT-20SE from the AC line and all test circuits.2. Heet the measures for preventing electrostatic damage.3. Remove the cover plate (two screws).The four screws fixing the module are accessible.4. Remove the four screws.5. Remove the module.• Wavelength 1550 nm: BN 3035/90.53 or BN 3035/91.53• Wavelength 1310 nm: BN 3035/90.54 or BN 3035/91.54• Wavelength 1310 and 1550 nm: BN 3035/90.59 or BN 3035/91.59
