Omnitron launches STM-1 coax-to-fiber media converter /ADVA Optical Networking device combines IEEE 588 and Synchronous Ethernet for mobile backhaul

MAY 12, 2009 -- Omnitron Systems Technology (search Lightwave for Omnitron Systems Technology), a provider of fiber-optic access systems for enterprise and telecom networks, has announced the availability of the iConverter STM-1 copper-to-fiber media converter. The iConverter STM-1 converts the electrical signals from an STM-1 or OC-3 75-Ω coax cable to optical signals on fiber. Targeted for telecom and enterprise applications where STM-1 or OC-3 transport is required beyond the limited distance of coax, the media converter transmits signals up to 5 km on multimode fiber and up to 120 km on singlemode fiber.

The copper port of converter provides two mini-BNC 75-Ω coax connectors that comply with ITU-T G.703 and Telcordia GR-253 standards for CMI-coded 155.52-Mbps electrical interfaces. Adapter cables are included to convert the mini-BNC connectors to standard BNC-type connectors. The fiber port accepts any standard, MSA-compatible 155.52-Mbps SFP transceiver. The iConverter STM-1 also supports CWDM SFPs to convert the signal to a specific optical wavelength and then connect it to a CWDM multiplexer to increase the fiber network capacity.

"The iConverter STM-1 media converter provides flexible STM-1 connectivity by overcoming the distance limitations of STM-1 coax cable," says Doug Baar, vice president of engineering. "Its modular design enables scalable fiber implementation with high-density chassis for the network core as well as compact chassis or standalone modules for the network edge."

The converter is available as a compact, unmanaged standalone unit or a chassis-managed plug-in module. The hot-swappable plug-in module can be mounted in a nineteen- or five-module chassis with any combination of redundant AC and DC power supplies. It also can be mounted in a two-module AC or DC powered chassis, or one-module chassis with AC or DC power input.

The standalone version of the iConverter STM-1 is wall-mountable. It is DC powered and is available with an external AC/DC power adapter or a terminal connector for direct DC power.




MAY 13, 2009 -- To address the growing need by mobile and backhaul service providers for more Ethernet-based transport capacity, ADVA Optical Networking (search Lightwave for ADVA Optical Networking) has introduced the FSP 150CC-GE206. The new device enables Ethernet and synchronization to be delivered over fiber-based Ethernet transport for service providers looking to deploy an Ethernet service optimized for mobile backhaul applications.

"Ethernet as a transport technology is appealing because it supports both higher data rates and a more attractive cost per megabit of supported traffic," explained Dr. Christoph Glingener, chief technology officer at ADVA Optical Networking. "With recent advances in synchronous Ethernet ("SyncE") standards, the protocol can now support mobile base station synchronization needs, and is also backwards compatible with 2G and 3G services."

The FSP 150CC-GE206 enables Ethernet transport to replace traditional T1/E1 or SONET/SDH-based synchronization with Ethernet synchronization based on ITU G.8261/2/4 and IEEE 1588. SyncE support includes in-band transmission and external synchronization inputs and outputs to support remote site and head-end applications.

Additionally, the service intelligence of the latest OAM standards such as 802.1ag, Y.1731 and RFC 2544 all help to guarantee that mobile SLAs are met. The ability to deliver intelligent Ethernet services that are functionally identical over a variety of access technologies is a key advantage of ADVA Optical Networking's FSP 150 product family, the company asserts.

The FSP 150CC-GE206 also contains personality module slots to ensure that the product can evolve with a service provider's changing requirements for service needs such as additional Ethernet ports or circuit-emulated T1s or E1s.

Low-touch provisioning and remote OAM capabilities in the FSP 150CC-GE206 ensure that unskilled craft can install and turn up services without any onsite provisioning. Optional WAN protection, redundant power supplies, and temperature hardening are designed to ensure high service availability for mission-critical applications, while SLA verification is ensured via in-service SLA monitoring. SFP optical devices also address a wide range of optical fibers, reaches and wavelengths.
