10GBASE-LRM SFP+ specifications
The 10GBASE-LRM SFP+ transceiver provides 10 GbE service at a wavelength of 1310 nm. This
SFP+ transceiver supports a reach of up to 220 m on 62.5 μm multimode fiber (MMF), as specified
in IEEE 802.3-2015 CL68. This SFP+ transceiver can also be used with standard single mode fiber
(SMF) to attain a reach of up to 300 m.
The following table lists the transmitter and receiver specifications for the 10GBASE-LRM SFP+
transceiver. 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.
