Abstract
This paper presents simulation and experimental studies of optical power penalties on the Versatile Link, a common R&D project on high-speed optical link for SLHC experiments. The 10 Gigabit Ethernet (10GbE) link model is examined and conservative link power penalties are predicted. We conduct parameter sensitivity analyses and find that the transmitter characteristics affect the link power penalties most. Power penalty differences of multi-mode and single-mode commerical transceiver modules over different fiber lengths are tested to be within the simulation limits. The optical power budgets are then proposed for different Versatile Link variants.

A crucial part of the power budget is based on the knowledge of device radiation tolerance
Summary
The physical layer of a typical optical link comprises the laser-based transmitter circuitry, the PIN photodiode-based receiver circuitry and the fiber medium. In the MM VTx Rx and the SM VTx Rx configurations, data flow from the versatile transmitter on detectors to a standard receiver in the counting room, using multi-mode and single-mode transceiver modules and over multi-mode and singlemode fibers, respectively. In the MM Tx VRx and the SM Tx VRx configurations, data flow in the opposite direction from standard transmitters in the counting room to the versatile receivers on detector. To ensure a link BER below 10−12 at the target data rate and fiber length, across operation temperatures and throughout life cycle, the optical power budget must be carefully planned ahead so that an adequate receiving signal-to-noise ratio is maintained under all conditions. Engineering judgment is called for in the assignment of a safety margin
