The new PacketPath plug-in cards allow access providers to minimize hardware costs by efficiently transporting time-division multiplexing (TDM) voice communications, Internet protocol (IP), and local area network (LAN) traffic on the same fiber-optic SONET ring. These plug-in cards for OSIRIS optical multiplexers are optimized for secure, high-speed IP or transparent LAN services.
The new FibreXpress hardware and software-the first in a series of second-generation FibreXpress products-has been optimized to use the full 1.062-Gbit/sec transfer rate of ANSI standard Fibre Channel. The FibreXpress network interface cards (NICs) provide efficient use of Fibre Channel's potential bandwidth, allowing the network to support sustained data transfers of over 100 Mbytes/sec. The new FibreXpress software offers full compatibility across differing backplanes and operating systems through the use of a multiprotocol software driver. The second-generation FibreXpress family includes NICs for PCI mezzanine card (PMC) and PCI systems.
The E100T, a 12-port autosensing Ethernet (10Base-T) and Fast Ethernet (100Base-T) module, and the new E1000F, a 2-port Gigabit Ethernet module, deliver Ethernet/IP directly over SONET. All cards switch Ethernet traffic at the card level with local gigabit IP packet engines on each card. The Cerent 454 optical-transport platform allows carriers to offer new LAN services on demand, switch and statistically multiplex Ethernet/IP traffic, and allow the traffic to interoperate seamlessly with the embedded SONET infrastructure.
The Quick-Talk RS-232 Voice Adapter can turn a fiber-optic data network into a voice network by plugging a handset or telephone into an RJ-11 connector (or DB-25 converter). It will be available in Intercom and PBX-compatible versions. The voice adapter enables technicians at a control center to pick up a handset, push a buzzer, and discuss immediate situations with a remote site. Quick-Talk, PBX-compatible, will allow dial-up telephone extensions to be plugged into most RS-232 circuits. The Quick-Talk Intercom is scheduled to ship in mid-summer, and the Quick-Talk PBX-compatible version is scheduled to ship in late 1999.

The Aurora-512 optical-crossconnect switch has a capacity of 512 optical connections. The switch operates at 2.5 Gbits/sec (OC-48/STM-16) for a total switching capacity of 1.28 terabits per second. It allows service providers to cross-connect high-speed optical signals (up to OC-48), bypassing the SONET/dcs layer. The Aurora-512 also performs additional optical- networking tasks such as restoration, dynamic wavelength management, and network gateway functions.
The S3060 high-performance transimpediance amplifier (TIA) is the industry's first 3.3V, 2.5-Gbit/sec OC-48 WDM solution, according to the manufacturer. It addresses both WDM and TDM applications and is engineered to provide increased sensitivity with 3 GHz of bandwidth and only 280-nA RMS of noise. The amplifier offers 3-kilohm differential transimpedance while reducing the overall external component count and requires only a decoupling capacitor and photodetector. Signal-to-noise ratio is 21.5 dB. The amplifier is priced at $35 each in quantities of 1000.
The max3890 3.3V, 2.5-Gbit/sec, SONET/SDH 16:1 serializer with clock synthesis and LVDS outputs is suitable for converting 16-bit-wide, 155-Mbit/sec parallel data to 2.5-Gbit/sec serial data in SONET/SDH and ATM applications. It forms a complete four-chip 3V, 2.5- Gbit/sec transceiver solution when used with the max3867 laser driver with APC, the max3866 TIA and limiting amplifier, and the max3880 1:16 deserializer with clock recovery. The max3890 includes a clock-generation function with power consumption of 495 mW.

New capabilities for the st2400a SDH/SONET test set includes verification on the end-to-end integrity of 2.488-Gbit/sec networks. Network operators installing high-speed packet-based networks will benefit from the new capabilities of the st2400a (Option 24), the first SONET/SDH test to be optimized for testing dense wavelength-division multiplexing (DWDM) client systems. It is optimized for testing the transmission quality of 2.488-Gbit/sec STM-16 (SDH) or OC-48 (SONET) networks transported over WDM systems and is available configured as a transceiver, receiver, or transmitter.
The TIA-HP optical to electric converter is a new addition to the TIA line capable of high optical-power handling. It is designed to meet the demands of "quantum-optics" experiments such as laser-diode intensity squeezing, nonlinear optics, high-sensitivity laser interferometry, and laser RIN measurements. Two outputs are provided: The auxiliary output provides as DC-to-15-kHz bandwidth signal that has a transimpedance gain of 1 kilohm. The converter is useful for measuring the total input optical power to the O/E converter. Maximum output is 10V. The main output provides a bandwidth of 10 to 100 MHz at a transimpedance gain of 2.5 kilohm.

The 3U-Closet Connector and Splice Housing (ccs-03u) combines the benefits of a connector housing and splice housing into a single unit for singlemode and multimode applications using three spaces in the equipment rack or cabinet. The design reduces the number of housings being installed, saving the user valuable and expensive rack spaces. Suitable for loose-tube, tight-buffered, and ribbon cables, the unit is rack-mounted for premises applications in the main crossconnect or intermediate crossconnection locations. Both panels and modules are available in a variety of connector types and come complete with factory-installed and -tested connectorized pigtails.
The FO 7010 cuts and removes Kevlar material from fiber-optic cables with high accuracy. Its pneumatically driven cutting system cuts the Kevlar to specification. A vacuum system, activated by a foot pedal, separates the Kevlar material from the optical conductor of the cable and is then positioned between the cutting head and anvil. The portable benchtop model guarantees repeatable results and a precise cutting performance, according to company claims.
The ULTRAsplice Module has a cradle that holds the splices main body while the collet rests on slots at either end. The gray locking nut is limited to the amount that can be opened. Therefore, the operator cannot twist the locking nut out too far, thus limiting the chances of any fiber breaking. The module can be ordered with double-sided tape that will allow the installer to place the entire splice and module combination into most trays, closures, or location where splicing is required.
