650 nm 100 Mbps EthernetFiber Optic Transceiver

with Termination for Bare POF

Seamless Digital to Light/Light to Digital Conversion FEATURES

• Simple low-cost termination solution for bare POF • Suitable for 1.5mm or 2.2mm POF • Compatible with IEEE 802.3u Fast Ethernet data communications standard • Logic interface compatible with both LVDS (Low-Voltage Differential Signaling) and CML (Current-Mode Logic)

DESCRIPTION

• Integrated CMOS LED driver IC Firecomms Ethernet OptoLock® transceiver combines a pair ofFirecomms Fast Ethernet fiber optic components within a miniature housing to provide instant termination for bare Plastic Optical Fiber (POF). This POF port significantly quickens and simplifies the connection of devices in communications and infotainment networks.The design of OptoLock enablesthe fiber to be cut and terminated to the exact required length on site, allowing even the most novice consumer to quickly and easily terminate the bare optical fiber.OptoLock is a RCLED-based 650 nm fiber optic solution designedto provide a Fast Ethernet communication link over POF. Firecomms’ unique RCLEDs provide high levels of light coupling into the fiber, with short rise and fall times, enabling Ethernet- compliant signaling over large core POF. The simple termination system in the transceiver and the flexibility of POF reduces installation costs to a minimum. The electrical inputs and outputs are compatible with low-voltage differential signaling levels for simple integration with Ethernet PHY chips. • Mechanically and electrically interchangeable with Firecomms-enabled SMI connectors • High-speed Resonant Cavity LED at red 650 nm with small emission aperture suitable for POF • Resonant Cavity LED reliability tested to over 400,00 hours lifetime • Integrated high sensitivity receiver IC and PIN-diode for one- step light-to-digital conversion • Integrated optics to efficiently focus and direct light • Optimized for high-speed Fast Ethernet of 125 Mbps • RoHS compliant
