Presentation Transcript

  1. OM3 PIE vs launch Fred Sugihwo, Jonathan King

  2. OM3 PIE-D measurements • TIA 2.2 demo fibres, 300m • Step response of channel measured using representative 10G TOSA DML transmitter and 10G ROSA • Isolated '1' synthesized from step response, and PIE-D calculated according to Bhoja_1_0704

  3. Launch Configurations SM Center Launch MCP Launch MMF MMF Tx Rx Tx Rx MCP SMCL + Connector Offset Launch MCP + Connector Offset Launch MMF MMF Tx Tx Rx Rx 6um SM-MM offset MCP 7um MM-MM offset

  4. OM3: effect of launch on TIA 2.2 demo reels • Worst case PIE-D • Color code Red: >5.5dB PIE-D Yellow: 4-5.5dB PIE-D Green: <4dB PIE-D • Best launch for OM3 fibers is single-mode centre launch

  5. OM3: effect of launch on TIA 2.2 demo reels • Input patchcord manipulated to give highest PIE-D • Best launch for OM3 fibers is single-mode centre launch • Direct centre launch into MMF also viable • 50um offset launch results in significantly higher PIE-D
