Finisar's broad product selection and innovative technology have made us the optical module manufacturer of choice for all major networking equipment vendors worldwide. We have taken a lead role in transforming the telecommunications equipment market from utilizing discrete optical components to leveraging the design and pay-as-you-grow flexibility offered by pluggable modules. Our products are fully compliant with Gigabit Ethernet, Fibre Channel, and SONET/SDH standards and operate at data rates up to 40 Gb/s and for distances greater than 200 km. They feature outstanding performance over extended voltage and temperature ranges, while minimizing jitter, electromagnetic interference (EMI) and power dissipation.
Finisar's Patented Digital Diagnostics
Finisar's XFP, XPAK, X2, 300-pin, SFP, SFP+, 2x6, 2x7, and 2x10 SFF and selected GBIC transceivers feature a microprocessor and diagnostics interface that provides performance information on the data link. Users can remotely monitor - in real time - received optical power, transmitted optical power, laser bias current, transceiver input voltage and transceiver temperature of any transceiver in the network. These digital diagnostic functions provide network managers with a highly accurate, cost-effective tool for implementing reliable performing monitoring.

Communicate up to 15 kilometers with EIA-232 port-powered transceivers. Flexible, Long-Range Fiber-Optic Communication - Send serial data up to 15 kilometers (9 miles) using multi-mode optical fiber with standard ST connectors. Use data rates from 0-40,000 bits per second.
Easy Application - Plug transceiver/modem directly onto a standard 9-pin serial connector (DB-9). No special mounting is required. Receives power from the host device via the connector; no separate power supply or power wiring is needed. Order transceivers/modems with male or female DB-9 connectors. Use switch to select DCE or DTE standard pin configurations, and eliminate the need for adapters. Transmits continuous light pulses, for simpler testing with an optical meter. Apply with ST pre-terminated fiber cables. Secure and Reliable Data Transfer -
Maximum bit error rate (BER) of 10-9. Far less susceptible to EMI/RFI than copper links. Vertical Cavity Surface Emitting Laser (VCSEL) technology provides component isolation and low power consumption.

General description
The ZL60301 is a very high-speed transceiver for parallel fiber applications. This transceiver performs E/O and O/E conversions for data transmission over multimode fiber ribbon. The transmit section converts parallel electrical input signals via a laser driver and a VCSEL array into parallel optical output signals at a wavelength of 850 nm. The receive section converts parallel optical input signals via a PIN photodiode array and a transimpedance and limiting amplifier, into electrical output signals.
The module is fitted with a pluggable industry-standard MegArray® BGA connector. This provides ease of assembly on the host board and enables provisioning of bandwidth on demand.

DESCRIPTION
The use of plastic optical fiber (POF) as a physical layer for 1394b (FireWire) is on the rise. Firecomms' FDK300S-101 Optical 1394b Transceiver Evaluation Kit allows the user to examine a data link over POF and to test the operation of the fiber optic transceivers.
This evaluation kit includes two evaluation boards, two multi-region DC power supplies and a 10 meter Step Index POF cable with SMI plugs at each end. Each board includes a Tx-Rx pair in an SMI socket. A CD
containing the data sheets and full design files for the PCB also is included.
The PCBs have been carefully laid out and tested to demonstrate the performance of the Firecomms 1394b Transceiver FDL300E/D over POF.
Each evaluation board carries the POF transceiver components in a through-hole SMI or IDB-1394 socket.
The electrical input and output lines from the transceiver are brought out to SMA connectors. The input accepts an LVDS/CML or PECL data source such as a Bit Error Rate Tester (BERT), Pattern Generator, or other signal source.

JDSU integrated fiber-optic transceivers provide a high speed serial electrical interface for connecting processors, switches, and peripherals using fiber optic technology. The 1 - 10 Gb/s serial optical converters are designed for the increased densities, higher performance, and lower power consumption required in high data rate network environments and applications. Those applications include gigabit Ethernet and Fibre Channel applications: storage networks to HBAs, backbone networks/LANs to NAS-as well as client/server environments, distributed multiprocessing, and data acquisition.

The MLX90121 is an ISO compliant 13.56MHz RFID transceiver integrated circuit.
The main features include user selectable modulation depth in write mode, whereas single sub-carrier ASK, FSK and PSK modulations are recognized in the read mode.
The receiver is based on a diode envelope detector, followed by an IF filter and amplifier. A logarithmic amplifier is used for single subcarrier ASK detection, ensuring fast and clean data recovery. The limiting output of the log amp is used for FSK and PSK recovery.
The transmitter uses a built in open drain output transistor, which can provide up to 250 miliwatts of RF power to a 50 ohms load with a 5 volts power supply using the recommended matching network. This is suitable for most short to mid range applications. A simplified antenna and matching network can be used, at the expense of a reduced reading range, for example in hand-held reader applications.
The chip is configured with a serial interface. A synchronization signal is available when the majority voting is used.
Digital part contains ASK, FSK (423 / 484kHz)and PSK (847kHz) decoders and a programmable encoder to facilitate data handling with a low cost microcontroller. The encoder can be programmed with 6 different patterns.
The chip can also be used as an analog frontend, in direct mode.
