GigOptix debuts low-power 14G VCSEL driver, TIA for SFP+/ADTRAN adds Active Ethernet to FTTP offerings

SEPTEMBER 9, 2010 — GigOptix, Inc. (OTCBB:GGOX) has announced the sampling of its new pre-production chipset for short-reach 2- to 14-Gbps serial optical interconnects. GigOptix asserts its latest offering provides a complete serial link chipset for applications up to 14 Gbps.

The GigOptix chipset comprises the HXT4101A VCSEL driver and the HXR4101A multi-rate receiver. The chipset is designed to not only enable low power consumption of less than 150 mW for 100-m links and 250 mW for 300-m links but also minimize the components required to implement a transceiver in order to reduce costs.

The HXR4101A receiver is a limiting transimpedance amplifier (TIA) with pre-emphasis output designed to eliminate the need for the post amplifier required in current alternatives; it supports multiple rates from 2 to 14 Gbps, making it suitable for systems requiring backward compatibility.

The HXT4101A VCSEL driver supports up to 14-Gbps data rates while consuming less than 65 mW, delivering 7-mA average and 7-mA modulation current.

The designs enable applications to extend from datacom into avionic and consumer applications.

“We are very excited to introduce this new chipset solution that uniquely addresses the current and future datacom short-reach needs,” stated Jörg Wieland, vice president and general manager of GigOptix-Helix, Zurich. “We developed these highly innovative products to address customer demand for high performance, lower power, and better cost-efficient solutions.”

SEPTEMBER 13, 2010 — ADTRAN Inc. (NASDAQ: ADTN) says it has added Active Ethernet products to its fiber-to-the-premises (FTTP) offering. The Active Ethernet products include a new Total Access 5000 Optical Line Terminal (OLT) and an enhanced suite of new Total Access 300 Series Optical Network Terminals (ONTs).

Active Ethernet is the latest addition to the portfolio of capabilities offered by the Total Access 5000 Multi-Service Access and Aggregation Platform (MSAP). The new offerings are designed to enable customers to take advantage of a point-to-point fiber infrastructure to provide up to 1-Gbps bidirectional bandwidth per subscriber.

Active Ethernet is a point-to-point technology that, in ADTRAN’s implementation, provides services up to 1 Gbps to every customer on a direct fiber connection that scales to support long-reach applications from small form factor pluggable (SFP) optics. The Active Ethernet offerings enable services to be deployed over a single fiber or a pair of fibers at distances of 10, 20, 40, or 80 km.

With up to 40 Gbps for the network interface, the Total Access 5000 is able to remove the bandwidth barriers of any Active Ethernet deployment, ADTRAN says. The Total Access 5000 24-port Active Ethernet OLT uses a simplified provisioning model and is fully integrated into the Total Access Element Management System (EMS) for plug-and-play operation, ease of troubleshooting, and complete performance monitoring.

“We want to offer our customers the most bandwidth possible from our fiber deployments and the Total Access 5000 Active Ethernet solution does just that. We are expanding services into many unserved and underserved areas. ADTRAN’s Total Access 5000 Active Ethernet solution provides 10-Gigabit Ethernet uplinks and transport, enabling us to address voice, video, and data needs for residential and business customers from a single chassis,” said Bill Knoop, plant manager, OmniTel. “We evaluated all the solutions on the market and selected the ADTRAN Total Access 5000. With an industry-leading warranty on a redundant, industry-proven, carrier-class chassis, ADTRAN was an easy choice.”

Expanding the Total Access 300 product line are three new Active Ethernet Optical Network Terminals (ONTs) for residential and business applications:

The Total Access 324E indoor ONT offers two POTS interfaces, four 10/100/1000 Ethernet interfaces and a SFP-based network connection
The Total Access 354E Single Family Unit (SFU) outdoor ONT offers two POTS interfaces, four 10/100/1000 Ethernet interfaces, and a SFP-based network connection in an outdoor enclosure
The Total Access 372E Small Business Unit (SBU) outdoor ONT includes eight POTS ports, four DS1 circuit emulated T1 interfaces, and two 10/100/1000 Ethernet interfaces with a SFP-based network connection in an outdoor enclosure
