Description
The Molex ParaLink is a high speed parallel optical link. It consists of separate 12 channel parallel
transmitter and receiver modules. The link is completed by connecting 12 fiber multi-mode ribbon cable.
The optical interface is a MT ferrule based SMC connector. The 86991-0200 & 86991-0300 series
operate up to 1.6Gbps data rate per channel.
The transmitter module consists of a 12 channel VCSEL array and parallel laser driver circuitry which
converts 12 parallel electrical data inputs to 12 parallel optical data output signals. The module is
compatible with low voltage differential signal data inputs (LVDS). The receiver module inputs 12 parallel
optical signals and converts these into 12 parallel LVDS electrical data signals through an PIN
photodetector array and receiver circuitry.
Molex ParaLink modules are fully compatible and interoperable with Infineon PAROLI modules.

Note 1: min data rate, DRmin depends on the disparity, D, of the data stream. The running disparity of a data stream is the difference of the number of
1s and 0s of that data stream. The disparity D is the maximum value of the running disparity for all possible starting points in the data stream.
Running disparity is set to zero at the starting point. Run length is the maximum number of consecutive 1s or 0s in the data stream.

Laser Safety
This optoelectronic transmitter is a Class 1 Laser Product that complies with 21 CFR Subchapter J.
According to classification methods specified in IEC 60825-1, Amendment 2, the product has an IEC
laser classification of 1M.
The transmitter contains a VCSEL laser diode array which emits laser radiation in the range of 820 to 860
nm. Light from the laser diode is attenuated so that the optoelectronic transmitter conforms to the Class 1
limit. To avoid possible exposure to laser radiation, do not open or alter the sealed housing of the
product.
No maintenance or service of the product may be performed.
Caution: The use of optical instruments with this product will increase eye hazard.
Invisible Laser Radiation. Do not stare into beam or view directly with optical instruments.
To ensure laser safety for all input data patterns, each channel is controlled internally and will be switched
off if laser safety limits are exceeded. A channel alerter switches the respective data channel output off if
the input duty cycle permanently exceeds 57%. The alerter will not disable the channel below an input
duty cycle of 57% under all circumstances. The minimum alerter response time is 1 us with a constant
high input. This means in the input data bit stream, ones (1s) in excess of a 57% duty cycle, consecutive
or non-consecutive, the time interval of excessive high input must not exceed 1 us, otherwise the
respective channel will be switched off. The alterter switches the respective channel from off to on
without the need of resetting the module.
All of the channel alerters operate independently. This means an alert within a channel does not affect
the other channels. To decrease the power consumption of the module, the unused channel inputs can
be tied to high input level. This allows a portion of the supply current in this channel to be shut down by
the corresponding alerter.
On the transmitter module pin #67 and #68, laser enable high and laser enable low, can be used to as an
input for connection with an Open Fiber Control (OFC) circuit to configure an IEC Class 1 link.
