FB01GKUJ
1.25 Gbps 850 nm, Industrial Fiber Optic
OptoLock® Transceiver
Datasheet
FB01GKUJ Revision A
1
DESCRIPTION
Firecomms’ plugless OptoLock® transceiver
features a small form factor housing containing a
CMOS based integrated transmitter and receiver
pair of opto‐electronic components lensed for
direct termination to Plastic Optical Fiber (POF). This
port for bare fiber significantly simplifies the optical
connection, (no plug required) thus reducing
installation and maintenance time for industrial,
medical and consumer applications.
The 1.25 Gbps OptoLock® transceiver combines an
850 nm transmitter with a high‐speed receiver
within a compact device capable of delivering bi‐
directional data links over 1 mm Step‐index Plastic
Optical Fiber (SI‐POF). For lower power and green
designs, the transceiver uses VCSEL (Vertical Cavitiy
Surface Emitting Laser) technology to deliver
operating power consumptions of less than 50 mW
which further reduces to a typical value of 28 uW
when placed into sleep mode.
OptoLock® is protected by U.S. patents 7,597,485
and 7,905,665, Chinese patents 101501545 A and
102135650 B and other international patents.

plane on the PCB. This is important to prevent cross-talk between Tx and
Rx and also to shield the components from external EMI/EMC and ESD.
