DWDM-SFP10G-ER 100Ghz DWDM-SFP10G-ZR 100Ghz DWDM-SFP10G-ER 50Ghz DWDM-SFP10G-ZR 50Ghz
Eoptolink CWDM SFP+ transceiver is small form factor pluggable modules with 18 waves: 1270~1610 20nm step, with the distance up to 80km.
Eoptolink BIDI SFP+ transceivers are designed for bi-directional 10G serial optical data communications using single fiber.
Eoptolink SFP+ transceiver are multi-purpose optical modules for 1~11.1Gbit/s, SDH/SONET, data transmission applications at 850nm, 1310nm and 1550nm.
Eoptolink SFP+ twinax and optical cables provide a cost-effective solution over fiber optics in short reach applications
The tunable DWDM transceiver is fully compliant to SFP+ MSA. It supports 50GHz DWDM 10Gb/s SONET/SDH, 10 Gigabit Ethernet, and 10 Gigabit Fibre Channel.
The SFP 10GB, or SFP+, or SFPplus is the enhanced small form-factor pluggable. It has the same shape as a 1G SFP but will support data rates up to 10 Gbit/s. On May 9, 2006 the specs were first published. SFP 10GB transceivers are interchangeable with SFP transceivers and can be used in the same cages as SFP transceivers. For 10 Gbps applications, SFP 10GB Optics have a smaller footprint and lower power consumption than XFP transceivers. The electrical interface to the host board for SFP and SFP+ modules is a serial interface. The SFP+ is also called SFP 10GB to avoid confusion with the 1G version. It will support 8 Gbit/s on Fibre Channel and 10 Gbit/s on Gigabit Ethernet and Optical Transport Network standard OTU2. It is a popular industry format because of the small shape (you can fit 48 pieces in 1RU). Furthermore, you can use the ports in 1G and 10G modes. The SFP 10GB comes in 4 different versions: SX, LX, EX and ZX. The SX version will work on Multi Mode fiber, the LX, EX and ZX will work only on Single Mode fiber. The LX will cover a maximum range of 10km, the EX of 40km, with the ZX reaching up to 80km. The optics always have a Tx side (sending laser) and a Rx side (receiver). The difference between the sending power (in dB) and the receiving power (in dB) is called the power budget and will determine the distance an optic can cover, where also the laser light (in nanometers) has an important role. In 2010, the ZR (80km) CWDM and DWDM SFP 10GB optics became available. The SFP 10G is available in SFP+, CWM SFP 10Gb, DWDM SFP+ 10Gb. Eoptolink, however, can offer you the whole CWDM DWDM spectrum for SFP 10GB. The SFP 10GB is also available as a BIDI optic, which has only 1 LC plus and will work on 1 single strand of Single Mode fiber. The buyers for SFP+ are typically storage vendors and private datacenter operators, such as Google, Amazon, Yahoo, Facebook. Other customers with large datacenter requirements may make the same decision and move forward with the SFP 10GB form factor as the technology becomes more prominent.
