Overview

Thank you for purchasing this Bluebell Opticom professional broadcast video product. If you are new to
Bluebell products, or to the subject of transmitting video and/or other data over fibre links, please take
the time to read through this document before putting the TDM-700 to use.

Introduction

The TDM-700 Series is a range of compact and rugged fibre interfaces designed specifically for
Outside Broadcast (OB) applications. They allow the implementation of a dual-fibre optical link between
a remote POV (Point of View) Camera and an OB van (or Control Room).
With all TDM-700 Series models, the optical link carries an HD/SD-SDI feed from the camera. Certain
TDM-700 variants can additionally:
• Add a return composite video feed for genlock or monitoring.
• Add bi-directional RS-232/RS-422 data and a GPI tally to the multiplex, allowing full remote
control of the POV.
• Add a 10/100 BaseT Ethernet link to the multiplex, allowing control of IP-based devices.
A single TDM-700 link requires two interfaces; one is installed at the POV Camera location, the other in
the OB van/Control Room. All interfaces are fitted with a dual optical port, separate fibres being used for
data in each direction.

Variants

Multiplex options
Four versions of the TDM-700 range are available; these differ in the types of additional information
which can be encoded along with an HD-SDI video signal (common to all versions).
• TDM-700: HD-SDI video plus Ethernet, RS-232/422 serial/GPI and genlock
• TDM-710: HD-SDI video plus genlock and RS-232/422 serial/GPI
• TDM-720: HD-SDI video plus RS-232/422 serial/GPI only
• TDM-730: HD-SDI video plus Ethernet only
Physical formats
TDM-700 Series interfaces are available in two formats: plug-in cards or stand-alone units. Some
versions can be supplied in either format.
Plug-in cards:
These are designed to fit the Bluebell BC-100 or BC-160 19" modular rack enclosures. The racks
can house six (BC-160) or fifteen (BC-100) interface cards, and are fitted with dual internal AC power
supplies. (The racks are also compatible with Bluebell BC Series interface cards.)
Alternatively, cards may be fitted into smaller aluminium chassis; the BC101 and BC102 hold one and
two cards respectively and require an external DC power source, while the BC120 holds three cards and
has an integral mains PSU.
