Query: The Miniature Optical Transmitter and Transceiver For the
  High-Luminosity LHC (HL-LHC) experiments   We present the design and test results of the Miniature optical Transmitter
(MTx) and Transceiver (MTRx) for the high luminosity LHC (HL-LHC) experiments.
MTx and MTRx are Transmitter Optical Subassembly (TOSA) and Receiver Optical
Subassembly (ROSA) based. There are two major developments: the Vertical Cavity
Surface Emitting Laser (VCSEL) driver ASIC LOCld and the mechanical latch that
provides the connection to fibers. In this paper, we concentrate on the
justification of this work, the design of the latch and the test results of
these two modules with a Commercial Off-The-Shelf (COTS) VCSEL driver.
