8943FC 4-Channel Fiber-Optic to 4-Channel Electrical Conversion Module

The 8935FC is a four-channel optical to electrical broadcast-quality fiber optic receiver module with two electrical outputs per channel. It can accommodate SD/HD-SDI video 270 Mb/s to 1.5 Gb/s as well as DVB ASI, unbalanced AES, and Grass Valley™ audio TDM interfaces. The optical circuitry is housed in dedicated strapmount SFP submodule devices mounted on the module circuit board. The SFP-DRX-1 supports both 1310 nm wavelengths and CWDM wavelengths (1270 nm to 1610 nm). This replaceable SFP optical technology allows for easy upgrade, reconfiguration, and servicing.

 
Key Features
  • Four-channel SD/HD-SDI fiber receiver (each SFP-DRX SPF has dual single-mode PIN receivers)
  • Also supports DVB ASI, AES, and Grass Valley audio TDM interface
  • Supports up to two SFP-DRX-1 devices for up to four fiber-optic inputs
  • Two reclocked outputs for stable long distance reception of each optical feed
  • Reclock bypass for non-SDI signal types
  • Inputs accommodates 1310 nm and CWDM wavelengths
  • Single-mode fiber
  • Can be used with the 8935CF transmitter and other fiber-ready modules for distances of between 0 and 50 km, depending on the transmitter
  • Meets SMPTE 292M/297M/259M signal specifications
Application
  • Receiving multiple high-definition video feeds over long distance fiber connections
  • For receiving implementing SD/HD-SDI optical tie-lines
  • To provide multi-channel receiving capability alongside the 8939FCA/8939FCB for an extremely compact multiplexed fiber solution
