10GbE Media Converter with 1x 10Gbase-T Copper Port and 1x SFP+ Module SlotThe XG2 is a 10Gbps Media converter allowing conversion between 10GBase-T and 10GBase-R.
The XG2 is used to convert high speed 10 Gigabit Ethernet Copper to 10 Gigabit Fibre for long haul transmission of data intensive backbone links. With 10 Gigabit Ethernet becoming more and more popular and the release of 10GBase-T Copper switches onto the main stream market, the requirement for 10Gig Media Converters is becoming more prominent.
10Gbps Ethernet
The 10 Gigabit Ethernet standard was first published in 2002 as IEEE Std 802.3ae-2002 and it is the fastest of the Ethernet standards. It defines a version of Ethernet with a data rate of 10 Gbps, ten times as fast as Gigabit Ethernet and it always connects with other device in full-duplex mode.
10GBASE-T (copper wire) overview
10GBASE-T, or IEEE 802.3an-2006, is a standard released in 2006 to provide 10 gigabit/second connections over unshielded or shielded twisted pair cables, over distances up to 100 meters (330 ft). 10GBASE-T cable infrastructure can also be used for 1000BASE-T allowing a
gradual upgrade from 1000BASE-T and auto-negotiation to select which speed to use. 10GBASE-T has higher latency and consumes more power than other 10 gigabit Ethernet physical layers.
10GBASE-R (fibre) Overview
10GBASE-R is a 10Gbps Ethernet connection that is based on IEEE802.3ae. It uses fibre as it's transmission media with different specifications of fibre, connector and transceiver. XG2 uses two standards, 10GBASE-LR and 10GBASE-SR.
10GBASE-SR
10GBASE-SR ("short range") uses 64B/66B encoding and 850 nm wavelength lasers. It is designed to support short distances over deployed multi-mode fibre cabling, it has a range of between 26 meters (85 ft) and 82 meters (270 ft) depending on cable type. It also supports 300 meters (980ft) operation over new, 50 μm 2000 MHz•km OM3 multi-mode fibre (MMF). The transmitter can be implemented with a VCSEL (Vertical Cavity Surface Emitting Laser) which is low cost and low power. MMF has the advantage of having lower
cost connectors than SMF (single-mode fibre) due to its wider core. 10GBASE-SR delivers the lowest cost, lowest power and
smallest form factor optical modules.
10GBASE-LR
10GBASE-LR is a Long Range Optical technology delivering serialized 10 gigabit Ethernet over a laser with 1310 nm wavelength connection on single-mode fibre via IEEE 802.3 Clause 49 64B-66B Physical Coding Sub layer (PCS) using a line rate of 10.3125. Single-mode optical cabling is used to interconnect transceivers at a distance spaced at 10 kilometers (6.2 mi), but it can often reach distances of up to 25 kilometers (16 mi) with no data loss. Fabry-Perot lasers are commonly used in 10GBASE-LR optical modules. Fabry-Perot lasers are more expensive than VCSELs (mentioned above) but their high power and focused beam allow efficient coupling into the small core of single mode fibre.
