10GBASE-LRM SFP+ specifications
The 10GBASE-LRM SFP+ transceiver provides 10 GbE service at a wavelength of 1310 nm. This
SFP+ transceiver can attain a reach of up to 220 m on 62.5 μm multimode fiber.
The following table lists the transmitter and receiver specifications for the 10GBASE-LRM SFP+
transceiver. These parameters meet the IEEE 802.3aq-2006 standard. The part number of this SFP
+ transceiver is AA1403017-E6.
Note:
VSP 7254XSQ has a PHYless design, which is typical for Data Center Top of Rack switches.
The benefits of a PHYless design are lower power consumption and lower latency. However,
due to the PHYless design, this transceiver is not supported.
In this table, the OMA, average launch power, and peak power specifications apply at TP2, after
accounting for patch cord loss.

For more information about the conditions used for the stressed receiver tests, and other
information, see the IEEE 802.3–2012 standard.
The following table (from IEEE 802.3–2012) describes the maximum channel insertion loss. The
channel insertion loss includes both attenuation and connector loss (1.5 dB); therefore the maximum
fiber attenuation is 0.2 to 0.4 dB.
