Almost always, the expression "save a penny, spend a dollar" is really true.
The inclusion of an O-ring in the F connectors prevents the risk of "flooding" of the connection. The effects can be quite disastrous and can range from degradation of the frequency response of the network to expensive breakdowns in remotely powered elements.
For this reason, and in at least outdoor cable runs, it is very convenient to always use connectors with O-ring. In indoor facilities, although the risk of water entering in the network is smaller, the O-ring can prevent the undesirable effects of condensation.

The Gateway needs to be configured to be detected by a CoaxManager.
The Gateway (Ref. 769301) is very particular type of slave. Its internal configuration has two independent blocks: a CoaxData slave with a coaxial interface (WAN) and a LAN interface which has two different interfaces: ethernet and WiFi.
In the installation and testing process the CoaxManager is executed by an ethernet port of the Gateway. When doing this, it is important to bridge the ethernet interface with the Coaxdata slave. This means that the Gateway should be previously configured in “AP Bridge”. If not CoaxManager will not be able to access the coaxial part of the device.
Once the installation and network optimization are set up, the initial configuration Router mode needs to be restored, as well as adjusting it depending on the final configuration required.
The GPON standard (providing services to the users) is defined by its class (A, B, C, B+, and C+). They differ in the transmitting power and the receiving sensitivity. Most common classes B+ (OLT/ONT) powers lie in the 1.5 dBm - 5 dBm / 0.5 dBm - 5 dBm ranges respectively. Receiving sensitivities <28 dBm / <27dBm respectively. Most common classes C+ (OLT/ONT)powers lie in the 3 dBm - 7 dBm / 0.5 dBm - 5 dBm ranges respectively. Receiving sensitivities <32 dBm / <30 dBm respectively.
The Ethernet standard (data sharing) was developed in order to share information among multiple devices with large capacity. This type of network does not have fixed transmission speeds and wavelengths like GPON networks. One of the most popular standards for Gigabit Ethernet (1000 Mbits) over optical fibre is 1000BASE-LX (1260 nm... 1360 nm,up to 10 km, single mode). For 10 Gigabit Ethernet the most popular standard is 10GBASE-LR (1310 nm, up to 10 km, single mode). In addition, most popular standards for twisted pair (up 100 m) are 1000BASE-T (CAT5, CAT5e or CAT6), and 1000BASE-TX (CAT6 or CAT7).
There was a need to create a device capable of sending/receiving and managing information from a single equipment called transceiver. The most widely used format is SFP (Small Form-factor Pluggable).
Currently, Televes provides two SFP for Gigabit Ethernet (fibre and twisted pair), one SFP+ for 10Gigabit Ethernet (fibre), and two SFP for GPON:
Televes introduces a full range of user terminals (ONT) to be selected according to the intended connection interface. The following table shows the different possibilities to choose from:
