This connection (often referred to as the Fronthaul network) can be a fiber to an installation where multiple remote base stations may be served. This fiber supports both single and multi mode communication. The fiber end is connected with the Small Form-factor Pluggable (SFP) transceiver device. [5]
SFP transceivers are available with a variety of transmitter and receiver specifications, allowing users to select the appropriate transceiver for each link to provide the required optical or electrical reach over the available media type (e.g. twisted pair or twinaxial copper cables, multi-mode or single-mode fiber cables). Transceivers are ...
While most of the modules in this list are Zigbee, Thread, ISA100.11a, or WirelessHART modules, some don't contain enough flash memory to implement a Zigbee stack and instead run plain 802.15.4 protocol, sometimes with a lighter wireless protocol on top.
1000BASE-SX GBIC. Gigabit interface converter (GBIC) is a standard for transceivers.First defined in 1995, it was used with Gigabit Ethernet and Fibre Channel.By standardizing on a hot swappable electrical interface, a single gigabit port can support a wide range of physical media, from copper to long-wave single-mode optical fiber, at lengths of hundreds of kilometers.
As premises networks are primarily copper-based, media converters can extend the reach of the LAN over single-mode fiber up to 160 kilometers with 1550 nm optics. [citation needed] Wavelength-division multiplexing (WDM) technology in the LAN is especially beneficial in situations where fiber is in limited supply or expensive to provision. As ...
A 10 Gigabit Ethernet XFP transceiver and a SFP+ transceiver side by side. The physical dimensions of the XFP transceiver are slightly larger than the original small form-factor pluggable transceiver (SFP). One of the reasons for the increase in size is to allow for on-board heat sinks for more cooling. [citation needed]
The small form-factor pluggable transceiver (SFP) module and its enhanced version SFP+, SFP28 and SFP56 are common form factors for Fibre Channel ports. SFP modules support a variety of distances via multi-mode and single-mode optical fiber as shown in the table below. SFP modules use duplex fiber cabling with LC connectors.
An optical module is a typically hot-pluggable optical transceiver used in high-bandwidth data communications applications. Optical modules typically have an electrical interface on the side that connects to the inside of the system and an optical interface on the side that connects to the outside world through a fiber optic cable.
