50051-1112, Issue 2

The Model 410 SDI-Over-Fiber Transport System is a high-

performance, cost-effective “throw-down” or rack-mounted solu

tion for distributing 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. Three Model 410 versions are

available, providing a range of input and output configurations.

The SDI transport capabilities, user support features, and compact

form factor make the Model 410 a highly unique product.

Model 410 General Features:

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

electrical (O2E) SDI transport

• Three format-independent SDI data paths over one

single-mode optical fiber

• 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

• Powered by 10-18 Vdc external source; optional

Anton-Bauer® battery mount available

• 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

• “Half-rack” enclosure weighs less than 2 pounds (0.9 kg)

Overview

The Model 410 SDI-Over-Fiber Transport System consists of half-

rack “thrown-down” units that are factory configured from among

three available choices. These configurations allow the needs of

specific applications to be directly supported. The Model 410-3T

is a 3-channel electrical-to-optical (E2O) unit. The Model 410-3R is

a 3-channel optical-to-electrical (O2E) unit. For “transceiver” appli

cations the Model 410-3T/3R provides three channels of electrical-

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

transport. Each unit’s front panel features a day-/night-readable

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

power on/off switch. The back panels include connections for DC

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

and an RJ45 jack for the Ethernet interface.

Technology

The Model 410 uses a novel hardware implementation to

transport three SDI signals over one single-mode optical fiber.

The three SDI signals, at rates of up to 2.97 Gb/s, are 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 410’s SDI input channels

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

transported.

Associated with each of the Model 410-3T’s SDI inputs is

a re-clocked and buffered loop-through output. These can be

extremely useful, allowing a signal source to be routed to an input

on a related piece of equipment. The SDI inputs on the Model

410-3T/3R are re-clocked but panel-space limitations prevent

loop-through outputs from being provided.

The optical input on the Model 410-3R and Model 410-3T/3R units

receive their signal via one single-mode fiber. The optical input is

de-multiplexed into three optical channels, which are converted

into electrical signals. Each of these SDI signals is then re-clocked

and sent to SDI output drivers. With the Model 410-3R each SDI

signal has two independent outputs. Space limitations dictated

that the Model 410-3T/3R provides one SDI output per channel.

Operating Power

The Model 410 is powered using an external source of 10-18

volts DC that is connected via a broadcast-standard 4-pin XLR

Model 410-3T Features:

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

• One single-mode optical output, transporting three SDI

signals using WDM/CWDM multiplexing

• Configurable laser on/off output control

• One single-mode optical input, WDM/CWDM de-multiplexed

to three re-clocked SDI signals

• Three SDI output channels, each with two independently

buffered outputs

• Monitoring of optical receive levels and SDI signal status

Model 410-3R Features:

• “Transceiver” with three SDI inputs and three SDI outputs

• One single-mode optical output and one single-mode

optical input

• Monitoring of optical output and input levels

connector. Included with each unit is a compact 100-240 volt input/12 volt DC output power supply. An optional Model 410 cover assembly provides an Anton-Bauer QR-Gold mount, allowing direct attachment of a broadcast-standard rechargeable battery. With the Model 410’s modest energy requirement one battery can support operation for many, many hours.
