50044-0513, Issue 3

The Model 400 SDI-Over-Fiber Transport System is a high-

performance, cost-effective, rack-mount solution for distribut

ing digital video signals over short and medium distances. The

system is compatible with all common broadcast serial digital

video formats and is suitable for use in remote trucks, live-event

video distribution, and fixed links associated with broadcast and

production facilities. Eight Model 400 versions are available, pro

viding a range of input and output configurations. This document

features the Model 400-12T and Model 400-12R units.

Model 400 General Features:

• Multi-channel electrical-to-optical (E2O) and optical-to-

electrical (O2E) SDI transport

• 12 format-independent SDI data paths over four

single-mode optical fibers

• Supports 3G (SMPTE 424M), HD (SMPTE 292), and

SD (SMPTE 259M) SDI, as well as DVB-ASI

• Fiber transport based on the SMPTE 297 standard

• Dual power capability: AC mains or DC; when both sources

are present system is AC mains powered and DC supply

acts as a backup

• Ethernet port provides system configuration and

performance monitoring using web pages or SNMP

• Front-panel features include status display, navigation

buttons, power switch, and LED indicators

• “1U” enclosure weighs less than 6 pounds (2.7 kg)

Overview

The Model 400 SDI-Over-Fiber Transport System consists of

single-rack-space (1U) units that are factory configured from

among eight available choices. The broad range of configurations

allows the needs of specific applications to be directly supported.

For example, the Model 400-12T is a 12-channel electrical-to-

optical (E2O) unit, while the Model 400-12R is a 12-channel

optical-to-electrical (O2E) unit. For “transceiver” applications the

Model 400-3T/3R provides three channels of electrical-to-optical

(E2O) and three channels of optical-to-electrical (O2E) transport.

The front panel of each unit features a day-/night-readable color

backlit display, menu navigation buttons, status LEDs, and power

on/off switch. The back panels include connections for AC mains

and DC power, ST or SC (optional) optical connectors, BNC

connectors, and an RJ45 jack for the Ethernet interface.

Technology

The Model 400 System uses a novel hardware implementation

to transport up to 12 SDI signals over four single-mode optical

fibers. The Model 400-12T’s 12 SDI inputs are arranged as four

groups, with each group of three SDI signals being transported

over one fiber at wavelengths of 1310, 1490, and 1550 nm. In

typical applications the launch power is such that signals can be

transported over a minimum distance of 10 kilometers.

SDI input signals can be SD (270 Mb/s), HD (1.485 Gb/s), or

3G (2.97 Gb/s). 3G signals can be in either Level A or Level B

format. The inputs also support video signals in the DVB-ASI

(270 Mb/s) format. Each of the Model 400’s SDI input channels

is independent, allowing any combination of rates/formats to be

transported.

Associated with each Model 400 SDI input channel is a re-clocked

and buffered loop-through output. These can be extremely

useful, allowing a signal source to be routed to another input on

the Model 400 or a related piece of equipment.

Typically a Model 400-12R receives the four single-mode fiber

signals that originate in a Model 400-12T. Each optical input is

de-multiplexed into three optical channels which are converted

into electrical signals. Each of these SDI signals are then re-

clocked and sent to two independent SDI output drivers. As such,

the Model 400-12R has 24 (12 pairs) of BNC output connectors.

Dual Power Capability

Model 400 units allow an AC mains source of 100-240 V, 50/60

Hz to be directly connected. They can also be DC powered using

a 10-18 volt source that is connected via a broadcast-standard

4-pin XLR connector.

Model 400-12T Features:

• Twelve SDI inputs, each with re-clocked loop-through output

• Four single-mode optical outputs, each transmitting three

SDI signals using WDM/CWDM multiplexing

• Configurable laser on/off output control

• Four single-mode optical inputs, WDM/CWDM

de-multiplexed to 12 re-clocked SDI signals

• Monitoring of optical receive levels

• Twelve SDI output channels, each with two independently

buffered outputs

Model 400-12T Back Panel Model 400-12R Back Panel If both AC and DC power sources are connected to a Model 400, the unit will be powered by the AC mains supply. Only if the AC mains source fails will a load be placed on the DC source. This allows a source of DC, typically a battery pack, to serve in a backup capacity. With this arrangement normal SDI-over-fiber transport operation can continue even if AC mains power is lost.
