1 PCN issued July 0 Please see new version available: FBMLVR Datasheet Rev. E FBMLVR 0 Mbps Fiber Optic LC Transceiver Data Sheet DESCRIPTION Firecomms industrial LC connector has a small form factor housing, compliant with IEC 0, which includes a pair of transceiver components to provide instant termination for Plastic Optical Fiber (POF) terminated in LC plug assemblies. The LC system offers compact termination ideal for rack mounted applications. The LC features a reassuring clear click when connected. This version of LC system carries a pair of high speed Fiber Optic Transceivers (FOTs) designed to provide up to 0 Mbps data links over POF in industrial environments. The FOTs are compatible with low voltage differential signalling (LVDS) for seamless integration into existing logic bus structures, and are ideal for use with an FPGA or ASIC. The transceiver has an electrical power saving feature. In the transmitter, the driver IC goes into a sleep state and the RCLED is switched off if there is no data or toning on the input bus. Similarly, if there is no optical signal present, the RX IC will switch into a sleep mode with RX power consumption reduced to a value of µa or less.

The transmitter (TX) and receiver (RX) are electrically shielded from each other to prevent crosstalk. To be effective this shield must be grounded. Both GND pins of the TX FOT must be connected to GND (they are not connected internally).. Power line capacitors should be located as close as possible to the FOT's DC power PINs.. The data lines are impedance matched differential pairs. The PCB layout for these tracks must comply to IEEE standards for highspeed data and impedance matching.. Note: The RD + and RD lines are already terminated with a 00 Ω resistor internally at the output stage

8 0. Part Name: LC Connector Part Number: FBMLVR. Lot No: LC0000 Date Code: D Quantity: FIGURE Packing tube for Firecomms FBMLVR Optical LC Transceivers PART HANDLING The transceivers are tested for handling in static controlled assembly processes (HBM). Cleaning, degreasing and post solder washing should be carried out using standard solutions compatible with both plastics and the environment. For example, recommended solutions for degreasing are alcohols (methyl, isopropyl and isobutyl). Acetone, ethyl acetate, phenol or similar solution based products are not permitted. In the soldering process, non halogenated water soluble fluxes are recommended. These components are not suitable for use in reflow solder processes (infrared/vapor phase reflow). The dust plug should remain in place during soldering, washing and drying processes to avoid contamination of the active optical area of each connector. The Moisture Sensitivity Level (MSL) classification of this device is a according to JEDEC J STD 00E. The shelf life of an unopened MBB (Moisture Barrier Bag) is months at < 0 C and < 0 % R.H. Once the Moisture Barrier Bag is opened the devices can be either a) Stored in normal factory conditions < 0 C and < 0 % R.H. for a maximum of hours ( Weeks) prior to soldering. b) Stored at < 0 % R.H. (Dry Cabinet).

9 PACKING INFORMATION Components are packed in PVC anti static tubes in moisture barrier bags. Bags should be opened only in static controlled locations, and standard procedures should be followed for handling moisture sensitive components.
