BBG-2EO-MK2 Features:

  • Dual independent fiber-to-coax paths – all in one easy to use throw-down box.
  • Full support of 5Mbps thru 3Gbps transport conversions, with seamless auto-mode EQ/ reclocking. No switches to set for different payloads.
  • Compatible with SMPTE 424M, 292M, 259M, 310M, M2S, DVB-ASI, and MADI audio
  • Dual-channel input lock status indicator. Optical Tx power meter field allows optical Tx confidence assessment.
  • Error-free pathological support. Full compatibility with other BlueBox™ Coax/Fiber units.
  • Compact size and low weight design easily affixes directly to camera or host device chassis. Optional BBG-MB mounting bracket provides rigid, secure mounting to mounting surfaces.
  • SFP-based EO converters provides state-of-the-art fiber performance, power consumption, and compactness.
  • Available with ST, LC, or FC fiber termination
  • USB remote control/status in addition to device indicator and switches
  • Powers directly from host equipment USB or standard corded power adapter. USB power and corded adapter can be simultaneously used to provide redundant power sourcing.

The Blue Box BBG-2EO-MK2 Dual Coax-to-Fiber converter unit is a new part of the BlueBox™ group of compact, rugged, and portable converter boxes.
Super-easy to use, Blue Box BBG-2EO-MK2 supports SMPTE 424M, 292M, and 259M as well as ASI and MADI audio on two independent coax-to-fiber paths.
Auto-mode EQ/reclocking automatically sets to the signal type being received while allowing unrecognized formats to be safely passed without reclocking (auto-reclock can also be manually disabled). Its wide operating range (from 5Mbps to 3Gbps) flexibly supports most professional digital serial communications.
Fully error-free pathological pattern operation is fully compatible with other professional fiber video interfaces. SFP-based EO converters provide state-of-the-art fiber performance, power consumption, and compactness.

BBG-2EO-MK2 receives its operating power via a USB connection or using an AC adapter connection. These power sources can be simultaneously used to provide redundant power sourcing.
