21 January 2004 Chatsworth, CA Lightwave -- LuminentOIC, supplier of metro transceivers and Fiber-to-the-Premise (FTTP) solutions, has announced availability of what it claims is the industry's first DWDM Small Form Pluggable (SFP) transceiver. The new Manhattan series of DWDM SFPs delivers twice the density and half the power consumption at CWDM pricing, say company representatives.
According to LuminentOIC, the new transceiver is the smallest DWDM pluggable transceiver form factor available, approximately six times smaller than the existing DWDM hot-pluggable Multi-source Agreement (MSA). Almost any equipment that features an SFP interface can immediately support 100-GHz spacing DWDM interfaces, including SFP-based CWDM systems.
Traditionally, CWDM solutions are used over DWDM alternatives based on cost, simplicity, power consumption, and equipment density. Alternatively, DWDM solutions provide maximum scalability in both channel count and distance. C-band DWDM systems currently employ 44 channels that can be amplified by low cost Erbium Doped Fiber Amplifiers (EDFA), enabling the reach required to service extended metro networks. The Manhattan series of transceivers combine the best features of both technologies, contend company representatives.
LuminentOIC's new DWDM SFP has low power consumption of 1.3 Watts over the full operating temperature range (-5 to 70 ° C). The next lowest power consumption pluggable DWDM transceiver--available in the larger Gigabit Interface Converter (GBIC) form factor--is rated at 2 Watts, and the typical Hot-Pluggable DWDM MSA transceiver is 4 Watts. The combination of small size and low power consumption enables a new generation of DWDM systems with twice the density of current systems.
The first product release incorporates this high level of pluggable transceiver technology. With integrated APD technology, receiver sensitivities better than -28 dBm at OC-48 are guaranteed. Digital performance monitoring is available for transmit power, receive power, bias current, APD voltage, TEC current, and temperature locking. Available in 44 channels on the 100-GHz ITU grid, the wavelength stability over temperature is +/-0.04 nm. The initial release also supports multi-rate functionality from 100 Mbits/sec to 2.7 Gbits/sec.
The Manhattan DWDM SFP product is available for sampling now with volume production starting in the second quarter 2004. Modules will be priced to reflect current CWDM transceiver pricing.
