Product Description
The LCP-10G3A4EDR-A is a multipurpose multi-rate optical transceiver module for
transmission at 850nm over multimode fiber. Supporting Ethernet and Fiber Channel
standards make it ideally suited for 10G data communication and storage area network
applications.
Its sub watt power consumption and its excellent EMI performance allow system design
with high port density. The small form factor integrates an 850nm vertical cavity surface
emitting laser (VCSEL) in an LC package and a PIN receiver. Approved Optics
Computer Peripheral’s module is lead free, RoHS compliant and is designed and tested
in accordance with industry safety standards.
Functional Description
The Transceivers convert information from electrical to optical format, and back again, at
different data rates depending upon the chosen standard. The transmit path consists of
an AC coupled 100 ohm differentially terminated driver coupled to a highly reliable
850nm VCSEL. The laser output may be disabled by pulling the TX_DISABLE line high.
The laser is also disabled if this line is left floating, as it is pulled high inside the
transceiver. The SFP+ MSA (Multiple Source Agreement) defines two RATE_SELECT
lines, one for the transmitter (pin 9) and one for the receiver (pin 7). Depending upon the
transceiver application, the transmitter RATE_SELECT line can switch between1 GBd
and 10 GBd.
The receiver path consists of a ROSA (receiver optical sub-assembly) for optical
electrical conversion, followed by a limiting amplifier to boost the electrical signal. A
LOSS_OF_SIGNAL (LOS) status line is provided to facilitate easy link detection.
Depending upon the transceiver application, optimum receiver bandwidth may be
configured using the receiver RATE_SELECT pin: for Ethernet applications to switch
between 1 GBd and 10 GBd data rates, and for Fiber Channel applications switch ≤/> 4
GBd data rates.
Not all transceiver versions require RATE_SELECT.
