POF transceiver delivers full Gigabit Ethernet performance

February 24, 2012 //By Julien Happich
Firecomms has started sampling its GDL1000 Gigabit POF transceiver, a world's first using Resonant Cavity 650 nm LED (RCLED) technology. The GDL1000 transceiver features a customized driver IC in the transmitter developed internally by Firecomms’ new mixed signal IC design team, a new high speed Resonant Cavity LED, and new receiver IC architecture to efficiently detect and convert the optical signals.

Traditionally, gigabit-class fiber optic transceivers are based on 850 nm and higher wavelength light sources, precision mounted on complex optical assemblies, which couple into 200 micron and smaller core glass optical fibers. Firecomms’ new gigabit-class transceiver utilizes an eye-safe, visible 650 nm (red) RCLED packaged in a transparent plastic moulded package with integrated lenses for easy coupling into 1mm core POF. In the near future it is expected the GDL1000 will be housed in the very popular LC connector, soon to be ratified by the International Electrotechnical Commission (IEC) for POF applications. By removing the significant additional costs associated with glass fiber, Firecomms GDL1000 POF transceiver unleashes an enormous opportunity for several markets. Using Plastic Optical fiber for installations where glass has been the only alternative removes the need for costly splicing or fiber processing equipment. Moreover, because the installer can cut the fiber to the required length and insert into the plugless OptoLock, expensive pre-assembled glass fiber patch cords are made obsolete. Optimized for data rates up to 1.25 Gbps, the GDL1000 transceiver is compatible with 1000BASESX and SGMii interface standards. With its LVDS interface, the transceiver also is compatible with a wide range of SerDes ICs operating at data rates down to 200Mbps. The GDL1000 transceiver is available in a non-magnetic version for use in medical MRI , CAT and PET applications. Transmission distance is 5m with SI POF and 30m with GI POF. The transceiver operates in the -20 to +70°C temperature range.
