Contact Closure OTP-4C Simplex or Duplex Contact Closure

Simplex or Duplex Contact Closure
The Optiva OTP-4C provides for the transmission of 4 channels of simplex or duplex contact closure, over long or short distances, using a single fiber. EMCORE contact closure cards come in two types: “CC”, which indicates latching operation (remembers the on/off position in the event of a loss of power) or “CF”, which indicates non-latching operation.

In addition, the OTP-4C is part of our innovative Optiva video, audio and data media transport system. Optiva was designed to maintain lossless fiber extension between input and output signals. New signals may be added without the need for additional fiber through our proprietary daisy-chain technology. The Optiva line of products also includes insert cards for up to 16 channels of multiplexing / demultiplexing, 16×16 matrix switching, optical add / drop, as well as remote system monitoring.

System Design
Optiva insert cards support both 19″ rackmount and compact tabletop or wall-mountable enclosures. The 3RU 19″ rackmount enclosures (Models: OT-CC-16 & OT-CC-16F) can support up to 16 insert cards as well as dual-redundant, hot-swappable power supplies utilizing two 100 watt or two 200 watt power supplies. Also available in the rackmount form factor is our 1RU enclosure (Model: OT-CC-6-1U) which can accommodate six insert cards and utilizes two 60 watt power supplies. For desktop or wall mounting applications there are one-slot (Model: OT-DTCR-1) and two-slot (Model: OT-DTCR-2) enclosures. Both use an external wall mount power supply.
