ZLE60300 Evaluation Kit for Pluggable Parallel Fiber Modules Evaluation Kit Data Sheet Description May 2007 The ZLE60300 evaluation kit is designed for highspeed evaluation of Zarlink’s ZL603xx family of pluggable optical parallel fiber 4x transceiver modules. The kit consists of two evaluation boards and one transceiver optical test fiber ribbon cable. The evaluation board is fitted with a MegArray® electrical socket where the optical module can be plugged in. SMA connectors are provided for the differential, ACcoupled, high-speed CML I/O interface. Ordering Information • ZLE60300 including • Transceiver evaluation board with MegArray® socket • Optical test fiber ribbon cable, 50/125 um with MPO/MTP® connectors Note: ZL603xx family pluggable optical transceiver should be ordered separately. Electrical Connections Each evaluation board is equipped with a switch to enable/disable certain functions within the module, see subsequent sections. LEDs on the evaluation boards indicate the status of different signal outputs. To ensure best performance, make sure to terminate unused data input/output connectors with 50 Ω singleended SMA-terminations. 1 Zarlink Semiconductor Inc.
