1 Prizm Fiber Optic USB 1.1 Link (P/N – 201000-xxx and 201030-
xxx) Overview
The Prizm Fiber Optic USB 1.1 Link provides a transparent USB 1.1 link over single mode fiber at
distances up to 10 kilometers. The Link consists of two boards, a Local Host and a Remote Hub. Both
boards may be mounted on 3U VME plates and powered from a VME backplane, or alternatively they
may be independently powered via a 2-pin connector.
The Local Host board connects to a standard USB 1.1 Host via an industry standard USB cable. A
single mode fiber optic transceiver on the board provides an SC connection to the Remote Hub end of the
USB Link.
The Remote Hub board carries four USB 1.1 peripheral ports that may be used to interface to various
USB 1.1 peripherals. A second, local USB hub may also be plugged into any of the four provided ports
to allow for additional connectivity. A single mode fiber optic transceiver on the board provides an SC
connection to the Local Host end of the Link.
The Link consists of two PC-104 based cards, (3.55” wide, 3. 5” long, .8” high), which have
standard PC-104 mounting holes. Both cards can provide pass through of all PC-104 backplane signals
and may be used in PC-104 based systems or they may be mounted separately and supplied with power
through a 2-pin terminal connector.

1.6 Prizm Fiber Optic USB 1.1 ink Adjustment and Troubleshooting
This section is meant to lend guidance while troubleshooting any problems that arise during operation
of either the Local Host or Remote Hub boards.
1.6.1 POWER SECTION TESTING:
If both the +5V Power LED and the +3.3V Power LED are out on the motherboard:
• Check for reversed polarity of power supply leads.
• Check for proper supply voltage (+5VDC min)
• Check for shorted power supply.
If only the +5V Power LED is out on the motherboard:
• Verify +5V DC is present at the source.
• If +5V is not available replace the board with a spare.
• If +5V is available check the +5V LED.
If only the +3.3V Power LED is out on the motherboard:
• Verify +5VDC across D6 (replace board if +5VDC is not available)
• Verify +3.3VDC across C14.
• If +3.3V is not available replace the board with a spare.
• If +3.3V is available check the +3.3V LED.
If both the +5V Power LED and the +3.3V Power LED are out on the daughterboard:
• Verify that the daughterboard is seated properly on the motherboard’s data headers.

1.6.2 OPTICAL SECTION TESTING:
If either Fiber Link light fails to illuminate after power has been applied to both boards and a fiber
optic tether is placed between the Local Host and Remote Hub units, there is a problem with the
optical link and one or more of the following conditions may be present.
• The fiber is broken or damaged.
• One of the optical transceiver modules is defective.
• Excessive light loss (low received optical power) is being experienced.
• The Prizm Fiber Optic USB 1.1 Link (not the optical transceiver module) is malfunctioning.
• There is not enough attenuation in the optical link and the receiver is saturating.
To determine if the fiber is broken, a laser module is out, or the board is malfunctioning, first:
• Check that the optical fiber cable is straight at connectors on board for minimum optic loss.
• Check the optical level with an optical power meter at each optical connection including any
external WDM’s or sliprings.
• If the above steps do not yield a solution, one or both boards may be malfunctioning. Try
replacing each board with a spare unit.
1.6.3 DATA SECTION TESTING:
If USB 1.1 data cannot be transmitted and received between the host and peripherals and the optic link
has been verified, there is a problem with one or both Prizm boards. Based on the LEDs present on
both boards, investigate the following:
• If one or both of the Fiber Link LEDs is not illuminated, refer to Section 1.5.2.
•
••
• If the USB Link LEDs do not illuminate on both boards as described in Section 1.4.3, verify that a
USB 1.1 compliant Host and at least one USB 1.1 compliant peripheral are attached to their respective
ends of the link. Also verify that both Fiber Link LEDs are illuminated.
•
••
• If the Host Present LED does not illuminate, verify that a USB 1.1 compliant Host is connected to the
Local Host Board and that both Fiber Link and USB Link LEDs are illuminated.
•
••
• If a Port 1-4 LED does not illuminate when a valid USB 1.1 compliant peripheral is attached to the
corresponding port, verify that there is a valid USB 1.1 compliant host connected to the Local Host
Board and that both the Fiber Link and USB Link LEDs are illuminated.
•
••
• If all LEDs behave as expected, but data cannot be carried across the link, examine any device drivers
needed to correctly operate your USB device. Connect the USB peripheral directly to the Host device
and verify proper operation. Then, reinsert the Prism USB Link and assess the status of the system
again.

2 Appendix A: Optical Considerations
2.1 Prizm Fiber Optic USB 1.1 ink Singlemode, Single Fiber Operation
The Prizm Fiber Optic USB 1.1 Link is configured for use with only singlemode fiber optic cable in
the umbilical and with fiber optic rotary joints (i.e. slip rings) at this time. Multimode cable cannot be
used.
Single fiber operation is advantageous to maximize the number of spare fibers in an umbilical or slip ring.
Single fiber operation is implemented by using two different optical wavelengths to carry the uplink and
downlink data on the same fiber. The two wavelengths are filtered and combined by either an integral or
external WDM to remove any interference between the uplink and downlink signals. The laser
transmitters are fabricated with a specific wavelength (i.e. 1310 or 1550 nm) and transmit at these
wavelengths. The optical receivers are responsive to a wide range of wavelengths (typically 1000 to 2000
nm). The filtering function of the WDM removes the local transmitter’s wavelength (the undesired
signal) from the remote transmitter’s wavelength (the desired signal). The local transmitter’s signal can
feed back into the local receiver by the reflection from a poorly terminated fiber optic connector and
cause link errors.

Checko t
3.1 General Prizm Fiber Optic USB 1.1 ink Installation Notes
NOTE: Please read all of this section prior to starting the installation process.
Test Equipment Required:
1. A USB host and at least one peripheral device.
2. Fluke
3. Oscilloscope
4. Fiber optic power meter (optional)
3.2 Prizm Fiber Optic USB 1.1 ink Installation Checkout Procedure
1. If installing the USB boards in standard 3U VME racks, obtain a Prizm supplied mounting plate
assembly and slide the cards into available backplane slots. If installing the USB boards in a PC-104
configuration, insert boards into stack as desired. If using a standalone configuration, use the supplied
mounting holes to secure the board in a system.
2. Supply power and ground to the boards using either a backplane or 16-gauge wire (or equivalent)
(+5VDC 1.5 Amps). Verify that the voltage is correct.
3. Connect a USB 1.1 compliant Host to the Local Host Board and at least one USB 1.1 compliant USB
peripheral to the Remote Hub Board.
3.3 Prizm Fiber Optic USB 1.1 ink System Installation Checkout
Procedure
1. Connect a singlemode optical fiber between the Local Host and the Remote Hub board.
2. Turn the power on to both devices and verify that the +5V and +3.3V power LED's light on both
motherboards and both daughtercards.
3. Using the USB 1.1 compliant host and peripherals, verify that data can be transferred correctly
between devices. Operation of the peripherals should be completely transparent.
4. Verify operation of the various LEDs on both boards as described in Section 1.4.3.
