PRELIMINARY PRODUCT SPECIFICATION
FC300R/FC300D
RCLED-Based
650 nm Fiber Optic
Transceiver Solution
in Lensed Side-Looker
Encapsulation
FEATURES
DESCRIPTION
• Meets the IEEE 1394b S200 (250 Mbps) specification
Firecomms' RCLED-based 650 nm fiber optic
• Resonant cavity LED
transceiver (FOT) solution is designed for maximum
• Small emission aperture
speed in IEEE 1394b S200 POF (plastic optical fiber)
• Narrow emission beam characteristics
applications. This FOT solution pairs Firecomms’
• Integrated optical lens
RCLED (resonant cavity light emitting diode)
technology with a 250 Mbps receiver in a new
• Narrow spectral width
package design that complies with the emerging IDB
• Low power consumption
• Emits at red 650 nm wavelength conforming to
current plastic fiber standards
• Housed in Firecomms exclusive Side-Looker
package with integrated optics to efficiently focus
and direct light
1394 standard. The integration of the FOT pair in a 50
meter POF link provides for a high-integrity link with
an attenuation overhead in excess of 3 dB.
• Provided in IDB 1394 form factor and suitable for
SMI and IDB 1394 Automotive Connector form
factors
