OE Solutions CWDM bi-directional pluggable modules target CPRI and OBSAI/Finisar unveils multi-rate serial 40-Gbps CFP-FR optical module, other products, at ECOC

OE Solutions Co. Ltd. has announced the production of single-fiber bi-directional SFP optical transceivers for CPRI and OBSAI standards with CWDM wavelengths. For the OBSAI application, the rates are 6.144, 3.072, 1.536, and 0.768 Gbps. For the CPRI application, the rates are 6.144, 3.072, 2.4576, 1.2288, and 0.6144 Gbps.

CPRI is the Common Public Radio Interface, which specifies the internal interface of radio base stations between the radio equipment control and the radio equipment. OBSAI is the Open Base Station Architecture Initiative.

The SFP optical transceivers can operate at all the CPRI and OBSAI data rates up to 6.144 Gbps within industrial temperature ranges, OE Solutions asserts. OE also offers the option of selecting a single-wavelength approach.

According to John Kwak, director of business development at OE Solutions, “Customers can now fully realize the cost and design benefits of utilizing CWDM wavelengths in a single-fiber solution. Having a single-wavelength option, customers can deploy a single-fiber bi-directional link with only one CWDM wavelength and double the number of links.”

Finisar Corp. (NASDAQ: FNSR) is using ECOC as a springboard to launch several new products, including what the company asserts is the first CFP-FR module that offers error-free operation at 40 Gbps. Other new products making their debut at ECOC include an 80-km SFP+ optical transceiver module and a GPON version of its “PON on a stick” product, an outgrowth of its acquisition of Broadway Networks in September of last year (see “Finisar acquires PON transceiver vendor Broadway Networks”).

Designed for 40-Gbps client-side network applications, the CFP-FR module has an MSA pluggable form factor and power consumption below 8 W. In addition to supporting 40GBase-FR operation, it also will support SONET OC-768 and OUT-3, say Finisar sources. Finisar will use EXFO’s FTB-8140 Transport Blazer to demonstrate its performance quality. The company will also demonstrate interoperability with a 300-PIN module. The CFP-FR is also plug-in compatible with SR4 and LR4 CFP modules, the company adds.

Meanwhile, the 10-Gbps DWDM 80-km SFP+ optical transceiver module is positioned as an alternative to DWDM XFP transceivers. It offers the same performance as XFP modules with lower power consumption and a smaller footprint, Finisar says. The SFP+ transceiver features internal dual CDRs for enhanced jitter performance, limiting electrical interface APD receiver, and an XFI-compliant interface.

Finally, the new “GPON Stick” offers the functionality of a standard GPON ONT within an SFP transceiver package. This enables switches, routers, and similar CPE to be connected to GPONs for fiber-to-the-business and wireless backhaul applications. The device is not being demonstrated at ECOC, and company sources declined to say when the product would reach general availability.
