Physical layer switches are scalable, versatile, multi-purpose devices that provide protocol-transparent switching for Fibre Channel (FC), Serial FPDP, shared-memory communications and other high-speed digital signals, up to 3.2 Gbps.  They enable users to easily and quickly change network and system configurations with an easy-to-use interface, to significantly reduce time and costs.

Curtiss-Wright, the originator of the Physical Layer Switch (PLS), offers a variety of scalable, versatile, multi-purpose PLS solutions, ideal for test labs, media conversion and a variety of other applications.

Curtiss-Wright’s Physical Layer Switches include:

  • VPX2500 6U VPX Crosspoint Switch/Media ConverterSupports multiple data rates up to 2.5 Gb/s, featuring rear I/O. It is a managed, non-blocking cross-point switch implemented on a VITA 46-compliant 6U, 0.8" VPX single-slot, conduction-cooled rugged card. It provides 18 ports with rear I/O backplane connections.
  • VLX2500 VME Physical Layer Switch The base VLX2500 switch is a single 6U VME64x card with eight ports. An 8-port expansion card is available to expand capacity to 16 ports in two VME slots. Each port input provides an option of clock reconditioning to reduce jitter.
  • VXS3200 VXS Crosspoint Fabric Switch Implemented on a 6U VXS air-cooled module, this PLS is a managed, non-blocking crosspoint fabric switch. It meets the MIL-STD-167-1 for type 1 vibration, and withstands a 15g lab shock test. The front panel includes 12 full duplex optical interfaces and one 10/100 Ethernet system communication port.
