The Multi-Function Link Series is a low-cost solution for applications requiring a full range of fiber optic link components. The HFBR-0501 series includes transmitters, receivers, connectors and cables specified for ease of design. This range of components is ideal to solve problems with voltage isolation/insulation, EMI/RFI immunity or data security. This simplifies optical link design through logic compatible receivers as well as each component. The optical key as well as the electrical parameter configuration of the connection HFBR-0501 family is fully guaranteed from 0° to 70°C. A wide variety of package configurations and connectors provide mechanical solutions for numerous designer application requirements. This transmitter and receiver assembly is designed for automated insertion and wave soldering in high volume/low cost assembly. The transmitter contains 660 nm light emitting diodes. The receiver includes a monolithic DC-coupled digital integrated circuit open-collector receiver Schottky output transistor. An internal pull-up resistor is available for the HFBR-25X1/2/4 receivers. A shield integrated into the receiver IC provides additional local noise immunity. The internal optics have been optimized to use plastic optical fibers with a diameter of 1 mm. Versatile connection specification includes all connector interface losses. Therefore, the common linking applications of optical computing have been simplified.

Application Literature

Application Note 1035 (Universal Link) VALOX® is a registered trademark of General Electric Company. Packaging and Handling The compact multi-function link pack is made of flame retardant VALOX® UL 94 V-0 material (UL File #E121562) and uses the same eight-pin dual in-line package as the standard configuration. Parts are available for vertical and horizontal mounting. These low profile multifunction link packs are stackable and enclosed to provide a dust seal. Simplex, Simplex Latching, Duplex and Duplex Latching connectors are available using simplex or duplex cables. Packaging orientation performance is the same as for Pinot vertical and horizontal packaging. For vertical multifunctional attachment of enclosures, designers have the option of using self-tapping screws to mount to the bottom of the package via a printed circuit board. Apps are unnecessary for most people. Packaging Housing Color Multifunction Link Assemblies and Simplex Connectors are color coded to eliminate confusion when connecting. The receiver is blue and the transmitter is gray, except for the HFBR-15X3 transmitter which is black. Handling multifunctional link components includes automatic insertion. When wave soldering is used the multi-function link assembly optical port plugs should be left in to prevent the port. Do not use the reflow process (ie infrared reflow or vapor phase reflow). Non-halogenated water-soluble flux (i.e. 0% chloride), rather than rosin-based flux, is recommended for multipurpose link assemblies.

The multifunctional link kit includes a moisture-sensitive device and a transport bag for moisture-sealed environments. If components are exposed to air for extended periods of time they may require a bake step before soldering. See label details on special shipping tube. Recommended chemicals for cleaning/degreasing alcohol: methyl, isopropyl, isobutyl. Fats: n-hexane, heptane, others: soap solution, naphtha. Do not use partially halogenated hydrocarbons such as 1,1.1 trichloroethane, ketones methyl ethyl ketone chloroform ethyl acetate, dichloromethane, phenol, dichloromethane or N-methylpyrrolidone. Also, Agilent does not recommend the use of halogenated cleaners with hydrocarbon potential environmental hazards

The interlocking (stacking) assembly (see Figure 1) can be packed horizontally by placing the pinned unit stack face up. Initially engage the interlocking mechanism from which the L-bracket body is slid under the wrapping above the L-trough body. Use straight edges, such as rulers, to align stacks of units. This technique prevents potentially harmful assembler pins that can occur on the fingers and hands in the bag. Stacked horizontal packs can be disengaged when necessary. Repeated stacking and de-stacking will not work on individual units. To stack vertical packs, press and hold one unit in each hand with the pins facing out and the ports on the bottom of the optics. Slide the L to fit the unit into the L-slot unit. Alignment for horizontal packaging is not required.

5 MBd link (HFBR-15X1/25X1) System performance is 0 to 70°C unless otherwise specified.

notes:

1. The propagation delay of one meter of cable is typically 5 nanoseconds.

2. Typical propagation delay measured at PR=-15dbm.

3. Estimated typical link life expectancy at 40°C is over 10 years at 60mA.

Transmitter electrical/optical characteristics 0°C to 70°C unless otherwise specified.

notes:

1. Measured at the end of a 0.5m standard optical cable with a large area detector.

2. Optical power, P(dBm)=10 Log[P(μW)/1000μW].

3. Rise and fall times are measured with a voltage pulse driving the transmitter and a 50Ω load in series. Broadband This response time is measured using an optoelectronic waveform analyzer terminated to the 50Ω input of a wideband oscilloscope

notes:

1. 1.6 mm below the seat surface.

2. A 0.01µF bypass capacitor must be connected from pin 2 to pin 3 of the receiver. The total wire length between capacitors and pins should not exceed 20 mm in length

Receiver Electrical/Optical Characteristics 0°C to 70°C, 4.75 V≤VCC≤5.25 V, unless otherwise specified

notes:

1. Luminous flux, P(dBm)=10Log[P(μW)/1000μW].

2. Measure with a large area detector at the end of the fiber optic cable.

3. RL opens.

4. If the pulse LED operating time is greater than 80 mA, it will cause the link tPLH transmission delay time to increase. Extended tPLH time helps

1 MBd link (High Performance HFBR-15X2/25X2, Standard HFBR-15X4/25X4) System performance under recommended operating conditions unless otherwise specified.

notes:

1. If IFPK>80mA, the duty cycle must keep IFdc≤80mA. Additionally, for IFPK > 80 mA, the following rules apply for pulse width applications: IFPK ≤ 160 mA: pulse width ≤ 1 ms IFPK > 160 mA: pulse width ≤ 1 μs, period ≥ 20 μs.

2. The propagation delay of one meter of cable is typically 5 nanoseconds.

3. Estimated typical link life expectancy at 40°C is over 10 years at 60mA.

4. Pulse LED operation with IFPK>80ma will result in increased link tPLH propagation delay time. The extended tPLH time helps to increase the pulse width distortion of the receiver output signal.

Transmitter electrical/optical characteristics 0°C to 70°C unless otherwise specified. Graphs for forward voltage and output power versus drive current.
