Cielo expands 1310 nm VCSEL-based parallel array family
"We have designed very compact and power efficient modules that enable system providers to significantly lower their capital and operating expenditures by reducing or eliminating power supplies, cooling fans, the number of boards needed, and even the number of chassis needed to achieve similar system functionality," said Mick Wilcox, product marketing for Cielo s arrays. "By combining two disruptive technologies, 1310 nm VCSELs and parallel array technology, we re enabling more efficient systems that will accelerate the deployment of low-cost, high-bandwidth next generation networks."
The density, or number of ports in a multi-port system, is currently limited by the size of the modules and connectors used on a board, with SFF representing the densest solution previously available. Cielo s parallel array modules replace multiple SFF transceivers with a more compact and power efficient solution. These new multi-port array modules are ideally suited for use in a range of different standards-compliant applications, especially those seeking more efficiency in size, power and cost.
Incorporating a monolithic array of directly-modulated 1310 nm VCSELs, Cielo s parallel arrays support 8 or 12 independent standards-compliant transmitters and receivers in separate dense transmit and receive packages. These modules are designed for multi-port systems that require density beyond what is currently available for transmission distances up to 25 km on single-mode fiber. In comparison with existing parallel optics modules at 850 nm, which are primarily designed for point-to-point interconnects, Cielo s 1310 nm arrays support multiple independent links that can be routed to multiple systems.
Each channel in these arrays includes independent signal detect and transmit disable functions and is frequency agile, capable of performing at various operational rates required for different applications. The modules have pluggable electrical connectors to enable easier field serviceability, are designed for superior EMI performance, feature CML I/O signal lines, and include a MTP optical connector. The new arrays are currently shipping to development partners, with general availability slated for the second quarter of 2002.
