Over several years of 10 gigabit Ethernet's R&D, there have been numerous different form factors and optics types introduced. The oldest, XENPAKs, still very popular as the install base is large, while the newest SFP+(or SFP plus) offers a much smaller form factor and the ability to offer 1G/10G combo ports on hardware for the first time. Currently XENPAK, X2, XFP and SFP plus are four standard 10G modules available.

Within these form factors are many different types of optical and electrical specifications; the only requirement is that the optics type match. It is perfectly acceptable to connect an X2 to an SFP, or a XENPAK to an SFP+, or any other combination.

XFP modules are hot-swappable and protocol-independent. They can operate over a single wavelength or use dense wavelength-division multiplexing techniques, signal rates of 10.30 Gb/s to 11.3 Gb/s, typically operate at near-infrared wavelengths of 850nm, 1310nm or 1550nm. Common applications include 10 Gigabit Ethernet, 10 Gbit/s Fiber Channel, synchronous optical networking (SONET) at OC-192 rates, synchronous optical networking STM-64, 10 Gbit/s Optical Transport Network (OTN) OTU-2, and parallel optics links. They include digital diagnostics that provide management that were added to the SFF-8472 standard. XFP modules use a LC fiber connector type to achieve high density.

XFP-SR
XFP-SR is 10Gbps fiber optic transceiver working at 850nm wavelength, typical working distance of 300 meters. XFP-SR is suitable for use in 10G datacom (belly-to-belly for high density applications) and storage area network (SAN/NAS) applications based on IEEE 802.3ae and Fiber Channel standards.

XFP-LR
XFP-LR is hot swappable fiber optic transceiver used for 10G networks like 10 Gigabit Ethernet, SDH, SONET. XFP-LR supports data transfer rate from 9.95Gbps to 11.1Gbps, with a max working distance of 10km.

XFP-ER
XFP-ER adopts cooled EML laser diode and PIN photodiode, fully compatible with XFP MSA and IEEE 802.3ae-2002, max working span of 40km.

XFP-ZR
XFP-ZR is 10Gbps fiber optic transceiver which is compatible with IEEE 802.3ae and Fiber Channel standards. XFP-ZR uses single mode optical fiber and its max working span can reach to 80km, working wavelength of 1550nm.

FiberStore provide high quality & cost effective 10G XFP transceiver moudles, including 10GBASE-SR for 300m with OM3 grade multimode fiber, 10GBASE-LR for 10km-20km, 10GBASE-ER for 40km and 10GBASE-ZR for 80km. All modules can support Digital Optical Monitoring (DOM) function. Compatible XFP transceiver modules like Cisco XFP, Juniper XFP, Brocade XFP, Dell XFP, 3Com XFP, Foundry XFP, Extreme XFP, Alcatel-Lucent XFP, Force10 XFP 10Gb, etc. are also available. Buying compatible Force10 XFP (for example) module is a cost-effective way, rather than buying an expensive original Force10 XFP transceiver.
