Installation Instructions

Warning:
Risk of BER increase
For proper SFP+ transceiver operation, ensure that at least 11 dB of attenuation is present
between the transmit and receive ports.
The reach for this SFP+ transceiver is up to 70 km* at a wavelength of 1550 nm.

* Achievable link distance is primarily dependent on cable plant insertion loss. 70 km is not possible
in some situations.
10GBASE-CX specifications
The 10GBASE-CX is a 2-pair twinaxial copper cable that plugs into the SFP+ socket and connects
two 10–Gigabit ports. The reach for this cable is up to 15 m with a bit error rate (BER) better than
10
-12
.
The 10GBASE-CX is a lower cost alternative to the optical SFP+ devices.
For more information about the 10GBASE-CX, including test and measurement information and
more specifications, see the IEEE 802.3–2012 standard. The following table identifies the part
numbers for specific cable lengths.
