Gigabit Ethernet TP network connection
The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of 100
meters. Cat. 5e is recommended.

It is more complex and comprehensive contrast to TP cabling in the fiber media. Basically,
there are two categories of fiber, multi mode (MM) and single mode (SM). The later is
categorized into several classes by the distance it supports. They are SX, LX, LHX, XD,
and ZX. From the viewpoint of connector type, there mainly are LC and BIDI LC.
Gigabit Fiber with multi-mode LC SFP module
Gigabit Fiber with single-mode LC SFP module
Gigabit Fiber with BiDi LC 1310nm SFP module
Gigabit Fiber with BiDi LC 1550nm SFP module
The following table lists the types of fiber that we support and those else not listed here are
available upon request.

Takes the Delay Time into Account
Theoretically, the switch partitions the collision domain for each port in switch cascading
that you may up-link the switches unlimitedly. In practice, the network extension
(cascading levels & overall diameter) must follow the constraint of the IEEE
802.3/802.3u/802.3z and other 802.1 series protocol specifications, in which the limitations
are the timing requirement from physical signals defined by 802.3 series specification of
Media Access Control (MAC) and PHY, and timer from some OSI layer 2 protocols such
as 802.1d, 802.1q, LACP and so on.
The fiber, TP cables and devices' bit-time delay (round trip) are as follows:
