Chapter 1 Introduction
1.1 Overview
TP-LINK’s JetStream Series SFP+ Transceiver contains two
types of transceivers: TXM431-SR and TXM431-LR. Both
transceivers support 10G Ethernet, making them very suitable
for business needs. TXM431-SR uses 850nm wavelength, it
supports maximum transfer distance of 300 meters, while
TXM431-LR uses 1310nm wavelength, with its maximum
transmission distance reaching as far as 10 km, providing
customers with a very flexible choice when deploying their 10G
Ethernet connection. Moreover, TXM431 Series transceivers are
hot-swappable, meaning that they can be added or removed
without interrupting the network.
