General Description and Applications
The JD850-XFP-LC.M is a multi-purpose optical transceiver module for 10Gbit/s datatransmission applications at 850nm. It is ideally suited for 10 GbE datacom (belly-to-belly for highdensity applications) and storage area network(SAN/NAS) applications based on the IEEE
802.3ae and Fibre Channel standards Designed for short range distances, the transceivermodule comprises a transmitter with a vertical cavity surface emitting laser (VCSEL) and a
receiver with a PIN photodiode. Transmitter and receiver are separate within a wide temperature
range and offers optimum heat dissipation and excellent electromagnetic shielding thus enablinghigh port densities for 10 GbE systems.

Digital Diagnostic Functions
JD850-XFP-LC.M Small Form Factor 10Gb/s (XFP) transceivers are compliant with the current
XFP Multi-Source Agreement (MSA) Specification Rev 4.5.
As defined by the XFP MSA, our XFP transceivers provide digital diagnostic functions via a
2-wire serial interface, which allows real-time access to the following operating parameters:◆ Transceiver temperature◆ Laser bias current◆ Transmitted optical power◆ Received optical power◆ Transceiver supply voltage
It also provides a sophisticated system of alarm and warning flags, which may be used to alert
end-users when particular operating parameters are outside of a factory-set normal range.
The operating and diagnostics information is monitored and reported by a Digital Diagnostics
Transceiver Controller inside the transceiver, which is accessed through the 2-wire serialinterface. When the serial protocol is activated, the serial clock signal (SCL pin) is generated by
the host. The positive edge clocks data into the XFP transceiver into those segments of its
memory map that are not write-protected. The negative edge clocks data from the XFPtransceiver. The serial data signal (SDA pin) is bi-directional for serial data transfer. The hostuses SDA in conjunction with SCL to mark the start and end of serial protocol activation. The
memories are organized as a series of 8-bit data words that can be addressed individually orsequentially. The 2-wire serial interface provides sequential or random access to the 8 bit
parameters, addressed from 000h to the maximum address of the memory.

Mechanical Specifications
DCI’s XFP transceivers are compliant with the dimensions defined by the XFP Multi-Sourcing
Agreement (MSA).

OPTICAL INSTRUMENTS
To meet laser safety requirements the transceiver shall be operated within Absolute Maximum
Ratings.
Note: All adjustments have been made at the factory prior to shipment of the devices No
maintenance or alteration to the device is required. Tampering with or modifying the performanceof the device will result in voided product warranty. Failure to adhere to the above restrictions
could result in a modification that is considered an act of “manufacturing”, and will require, underlaw, recertification of the modified product with the U.S. Food and Drug Administration (ref.21
CFR 1040.10(1)).
