datasheet

The VS252-3G is a full featured digital video transport processor supporting signal rates from 10Mbps through 3Gbps.

The VS252-3G is ideal for telco environments where

both large losses and poor dispersion characteristics

associated with legacy fiber plant are overcome

with carrier class long-reach optics and unique

jitter management techniques ensuring the highest

signal integrity possible. With support for 3G video,

signal integrity (EDH/CRC) monitoring and test pattern

generation, the VS252 supports all optical video

transport applications over 1310nm, 1550nm, CWDM

and DWDM (LSB dithering) wavelengths.

Applications

• Professional broadcast contribution

• Metropolitan fiber networks

• Live sports and event contribution

Key features

• Universal digital video transport supporting 10Mbps

to 3Gbps signals with jitter management and

non-jitter management modes

• Jitter management at 2.970Gbps and 2.967Gbps

3G-SDI, 1.485Gbps and 1.4835Gbps HD-SDI/HD-SDTI

and 270Mbps SD-SDI/SD-SDTI/DVB-ASI

• Full CRC and EDH checks for 3G-SDI, HD-SDI and

SD-SDI signals

• Built-in SD-SDI, HD-SDI and 3G-SDI test signal

generator for remote network testing

• Rate locks for 270Mbps and 1485Mbps, that

prevent higher rate video signals from being

passed in tariffed applications

Universal transport

Transports 3G, HD and SD pathological patterns

without additional scrambling at 1310/1550nm and

CWDM LSB dithering provided for DWDM applications.

Non-standard video rates are supported in bypass

mode with jitter management disabled.

Highly flexible

Universal transport card configurable as electrical

to optical (E-O), O-E and O-O repeater, wavelength

shifter, changeover switch or automatic protection

switch with any wavelength for ease of sparing.

Protection switching

Supports revertive and non-revertive modes for

automatic protection switching providing network

resiliency and path protection.

SFP optical interfaces

Supports wideband 1310nm and 1550nm wavelengths

in addition to CWDM and DWDM wavelengths. Typical

30dB optical budget in HD, SD and ASI modes.

Signal integrity tests

Provides full CRC and EDH checks on input video

signals to ensure signal integrity.

Test pattern generation

Supports all SD-SDI, HD-SDI and 3G-SDI rates with

options for different patterns. Also supports null

packet generation for DVB-ASI test pattern.

Remote upgrade

Supports remote firmware upgrades via the AEMS

(Ventura shelf element manager) for the latest in

function upgrades and fault resolution.

NEBS Level 3

Certified to perform in telecommunication

installations providing reliable performance in harsh

environments.

Element managementThe Ventura AEMS shelf element managers, FCS183-AEMS and FCS101-AEMS, provide a comprehensive set of status, control and alarm variables through a Web interface. The AEMS is a powerful Linux based embedded management system that also supports SNMP and XML. It also acts as an agent for card upgrades, storing multiple images for each card in the VS103 or VS101 chassis. Users can apply these images to install upgrades from a remote location

Physical and environmentalRequires only one slot of either the VS103 ten-slot chassis or the VS101 three-slot chassis.
