Data Sheet
Description
The X2 LRM fiber optic transceiver is an “intelligent” optical
module which incorporates the complete physical layer
functionality of 10GbE on multi mode fiber with data rate
of 10.3Gbps. The X2 LRM module includes a transmitter
that incorporates an uncooled, directly modulated 1.3 µm
Fabry-Perot laser. The receiver subassembly includes a PIN
photodiode and a linear/AGC trans-impedance amplifier.
To cope with the effect of modal dispersion of multi mode
fibers at 10 Gbps over the distances specified in the IEEE
802.3aq LRM standard, an electronic dispersion compensa-
tion circuit is used. The MUX/DEMUX, XAUI interface and
MDIO management functions are all integrated into the
module, as is a precision oscillator. The module is compli-
ant to the X2 Multi Source Agreement specifications.
Applications
• Ethernet switching systems
• Ethernet peripheral interface
• Computer system I/O
Features
• Compliant with IEEE LRM Standard
- Draft P802.3aqTM/D4.0 for Type 10GBASE-LRM
• Compliant with X2 MSA Issue 2.0b
• Standard SC Duplex fiber optic connector
• Standard 70 pin electrical connector
• Four wide XAUI Electrical interface
• MDIO Management Interface
• Front Panel hot pluggable
• Digital Optical Monitoring (DOM) provides Tx/Rx power,
laser bias current, and module temperature
Specifications
• 220m reach on OM1, 0M2 and OM3 Multimode Fiber
Cables
• Total Power Dissipation less than 4W

Notes:
1. RMS spectral width is the standard deviations of the spectrum.
2. The OMA, average launch power and peak launch power specifications apply at TP2. This is after each type of patch cord. For information: Patch
cord losses, between MDI and TP2, differ. The range of losses must be accounted for to ensure compliance to TP2.
3. Peak optical power can be determined as the maximum value from the waveform capture from the TWDP test, or equivalent method.
4. This encircled flux specification, measured per IEC 61280-1-4, defines the near field light distribution at TP2 when the MDI is coupled directly into
the appropriate patch cord.
5. This value will be met for several different independent test conditions defined in Section 68 of the IEEE 802.3aqTM/D4.0: 1. Comprehensive stressed
receiver test (two separate conditions; Pre-Cursor and Post-Cursor tap weights); 2. Simple stressed receiver test; 3. Jitter tolerance (two separate
frequency/p-p amplitude conditions)
6. This value will be met for test conditions defined in Section 68 of the IEEE 802.3aqTM/D4.0 for comprehensive stressed receiver test symmetrical
tap weights.
7. With ER ≤ 10dB.
