Based on MSA (Multi-source agreement), The are many forms of fiber optic transceivers, each pluggable optical transceivers with different transmission distance options, it including form factors, such as the SFP, SFP+, XENPAK, QSFP, XFP, CFP etc.;
GBIC – First generation transceivers with SC fiber interface, commonly used with Gigabiy Ethernet and fibre channel, also available for CWDM with wavelength/channel options.
SFP – Small form-factor pluggable transceivers, resulting in increased density, capable of data rates up to 6Gb/s, available in 850nm, 1310nm, and 1550nm, bi-directional option (1310nm/1490 or 1310nm/1550nm), and DWDM and CWDM wavelengths/channel options. Distances range up to 160km.
XENPAK – Larger form transceivers with capability of data rates up to 10Gb/s, with a range of a few metres up to 80km. DWDM and CWDM wavelengths/channel options.
X2 – Transceivers with the capability of data rates up to 10Gb/s, with a range of a few metres up to 80km. DWDM and CWDM wavelengths/ channel options.
XFP – Transceivers with the capability of data rates up to 10Gb/s with a range of a few metres to 80km. DWDM and CWDM wavelengths/channel options, including tuneable DWDM options.
SFP+ – Transceivers with capability of data rates from 8Gb/s to 10Gb/s, with range of a few metres up to 80km. DWDM and CWDM wavelengths/ channel options. Full range of DAC/Twinax cables available.
QSFP+ – Quad small form factor pluggable transceivers, capable of data rates up to 40Gb/s. Range of passive DAC cables and AOC cables available.
CFP/CFP2 – Transceivers with capability of data rates up to 100Gb/s, with range of up to 10km. Suitable for use in datacentres, metropolitan area networks, DWDM systems, IP switches and storage area networks.
QSFP28 – Quad small form factor pluggable transceivers, capable of data rates up to 100Gb/s. Also a range of passive DAC cables and AOC cables available.
