Some Great 10G Fiber Transceivers

10G optical transceivers are created for 10G or 10 Gbit/s data transmission applications which include 10 Gigabit Ethernet, 10 Gbit/s fiber channel, as well as SON. Due to 10 Gigabit Ethernet for many years, a variety of form factors and optical modes have been introduced.

Today, the series of 10G transceivers primarily have 10G XENPAK, 10G X2, 10G XFP as well as 10G SFP. At the beginning, XENPAK belongs to the first MSA for 10GE which has the biggest size. Then X2 appeared as the standard in the competition with smaller size. Later XFP came into our eyes with smaller volume. SFP supplies a smaller size in appearance and offers 1G/10G combo interfaces on the hardware. Here, a guide to these current modes of modules and optical standards in the use can be seen as follows.

As a 10G optical transceiver, XENPAK can support all fiber interfaces as the definition in IEEE 802.3ae, with the rate of 10.3 Gb/s,9.95 Gb/s or 3.125 Gb/s. In XENPAK, XAUI port and knowledge shaping (CDR) performance are designed, conforming to the XENPAK MSA protocol and meet the need of the application of 802.3ae Ethernet protocol 10GB. This module contains XENPAK 10GBASE-SR with 300m (multi-mode OM3 fiber), XENPAK 10GBASE-LRM multi-mode fiber with 220m, XENPAK 10GBASE-LR single-mode fiber with 10 to 20 kilometers, XENPAK 10GBASE-ER single-mode fiber with 40 kilometers, as well as XENPAK 10GBASE-ZR single-mode fiber with 80 kilometers.

In X2, one SFM 10 Gb/s swapping optical transceiver is defined to be optimal for 802.3ae Ethernet, ANSI/ITUT OC192/STM- 64 SONET/SDH ports, ITUT G.709, OIF OC192 VSR, INCITS/ANSI 10GFC (10 Gigabit fiber channel) and other 10 Gigabit applications. At the beginning, 10G X2 focused on fiber links of 10km which was really fit for Ethernet, fiber channel and telecommunication switches and standard PCI (outer assembly interconnection) based server and storage connection. 10G X2 is smaller in the size than XENPAK yet keeps the fully developed electrical I/O specification according to the XENPAK MSA and keeps on offer perfect thermal functionality and electromagnetic shielding. This series of optical transceiver contain X2-10GB-SR, X2-10GB-LR, X2-10GB-ER as well as X2-10GB-ZR, which are designed according to the X2 MSA and IEEE802.3ae for the settlement of integrated system, optical dealer as well as other IT dealers.

In fact, XFP represents one standard for transceivers in the computer network and telecommunication links with high speed that employ optical fiber. 10G XFP occasionally operates at the wavelength of 850 nm, 1310 nm or 1550 nm near-infrared radiation (color). The major applications contain 10 Gigabit Ethernet, 10 Gbit/s fiber channel, synchronous optical networking (SONET) at rate of OC-192, SONETSTM-64, 10 Gbit/s optical transport network (OTN) OTU-2, as well as parallel optical module links. They are able to work over a single wavelength or employ the dense wavelength division multiplexing technique, including digital diagnostics which offer administration added to SFF-8472 standard. XFP modules utilize one mode of LC fiber connector for high density. Series of 10G XFP optical transceivers contain XFP-10G-MM-SR, XFP-10GLR-OC192SR, XFP-10GER-OC192IR as well as XFP-10GZR-OC192LR.

10G SFP+ transceiver is the optical module having multiple uses for data transmission applications with the rate of 10Gbit/s at 850nm, 1310nm and 1550nm. 10G SFP+ transceiver is really fit for data communication and storage space network (SAN/NAS) applications according to the IEEE 802.3ae and fiber channel standards, fiber channel 10G, 8.5G, 4.25G, 2.125G, 1.0625G, 10G BASE-SW/SR/LR/ER, as well as 1000Base-SX Ethernet. In the 10G SFP optical transceiver series, SFP-10G-SR, SFP-10G-LRM, SFP-10G-LR, SFP-10G-ER, SFP-10G-ZR, SFP-10G-LW, SFP-10G-LH, SFP-10G-LX as well as SFP-10G-ZW are included.
