Gigalight unveils 3G video SFP transceivers
Gigalight has introduced its 3G Video SFP optical transceiver modules for SD-SDI (270 Mbps), HD-SDI (1.485 Gbps), and 3G-SDI (2.97 Gbps) applications. The modules are designed for long-distance and HD video signal transfer, and come in four models: transmitters, receivers, transceivers, and transmitter/receiver. The modules will support transmission distances ranging from 10 km to 80 km.Compared to traditional modules, the 3G video SFPs better overcome transmission impairments to provide long reach at full bandwidth, the company asserts. Gigalight’s 3G video SFP uses MCU control and high accuracy DDM to meets the such specifications as SMPTE 424M, 292M, 259M-C, 297, etc.The new 3G video SFP is Gigalight’s first offering in the video optical communication field.
OE Solutions extends 40-km SFP+ to industrial temperature range
supplier of optoelectronic transceivers for wireless and wireline optical communications, recently announced the introduction of industrial temperature-operating SFP+ transceivers for 10-Gigabit Ethernet (10-GbE) 40-km reach applications.According to the company, this 40-km-reach SFP+ is compliant with IEEE 802.3ae 10G BASE-E, the SFP+ MSA, and digital diagnostic SFF 8472 Rev10.2 while operating from -40 ° C to +85 ° C case temperature. This 1550-nm transceiver is also RoHS compliant and has a typical data rate of 10.3 Gbits/sec with a link budget of greater than 15 dB.
The RSPX0SER-IT5 10-Gbit/sec 40-km SFP+ is the newest addition to OE Solutions' industrial temperature (IT) 10-Gbit/sec SFP+ and XFP module series, which also includes the RSPX0SLR-IT3 10-km SFP+; RTXX0SER-IT5 40-km XFP; RTXX0SLR-IT3 10-km XFP; and RTXX0SS1-IT3 2-km XFP."As SFP+ and XFP become the industry's de facto form factors for 10-Gbit/sec transceiver modules in the high-density port applications, expanding their operation to the industrial temperature range is paramount for use in the hardened environment such as outdoor applications," explains Dr. MoonSoo Park, CTO and head of engineering at OE Solutions. "At OE Solutions, leveraging our leadership in the industrial temperature Small Form Pluggable technology, we have pushed the long-reach SFP+ and XFP to extend its operation to the extreme temperature range for the first time in the transceiver industry."
Finisar intros EPON Stick in an SFP for DOCSIS Provisioning of EPON
leveraging its acquisition of Broadway Networks, has announced the availability of an EPON (Ethernet Passive Optical Network) Stick. Finisar describes the EPON Stick as the first Small Form-factor Pluggable Optical Networking Unit (SFP ONU) that interoperates with other EPON equipment based on CableLabs’ DOCSIS Provisioning of EPON (DPoE) specifications.
Finisar says it participated in the development of the DPoE 1.0 specifications and the recent interoperability testing at CableLabs. (For more on DPoE, see this article in the January/February 2011 issue of Lightwave.)The DPoE effort aims to enable cable operators to supply business services via EPON technology. Using their existing provisioning systems and processes built around DOCSIS, operators can deliver both IP and Ethernet based services with DPoE products like the EPON Stick. "We are proud that Finisar's EPON Stick is the first in an MSA SFP footprint compatible with EPON and DPoE," said Dr. Jianhui Zhou, vice-president and general manager of Access Products at Finisar. "It offers operators the advantages of automated provisioning with DPoE, while still allowing the flexibility of using a wide variety of Ethernet network interface devices, integrated access devices, switches, and routers. Finisar's EPON Stick comprises pluggable transceiver optics and an EPON MAC with DPoE provisioning within the SFP package. Operators can insert the EPON Stick into any SFP host and operate a single demarcation device at the customer premises. Finisar believes the reduced complexity, reduced power consumption, and increased reliability of a single box approach will prove attractive to both the operator and their customers or subscribers.In addition, operators that either do not yet have DOCSIS provisioning or have not yet used it for business services can use the EPON Stick with any EPON system to achieve DPoE interoperability.
