• Manufacturer Part Number: v23836-c18-c63
• Description: Transceiver With Duplex Receptacle Single Mode 1300 Sonet Oc-3 Stm-1
• Manufacturer: Infineon Technologies Corporation

Application Notes
ATM transceivers and matching circuits are high frequency components and shall be
terminated as recommended in the application notes for proper EMI performance.
Electromagnetic emission may be caused by these components.
To prevent emissions it is recommended that cutouts for the fiber connectors be
designed as small as possible.
It is recommended that the Tx plug and the Rx plug be separated with a bar that divides
the duplex SC opening.
