Source Photonics launches CWDM GPON OLT and ONT transceiver product family

At last week’s 12th China International Optoelectronic Exhibition (CIOE 2010) in Shenzhen (6-9 September), optical communications product maker Source Photonics Inc of Chatsworth, CA, USA (a subsidiary of system maker MRV Communications Inc) launched its CWDM (coarse wavelength division multiplexing) GPON OLT and ONT transceiver product family.

Source Photonics claims that its CWDM GPON OLT (optical line termination) and ONT (optical network terminal) provide an alternative cost-effective solution to expand total capacity to 10Gb/s or beyond in gigabit passive optical networks (GPON). It is based on existing mature GPON technology using multiple CWDM channels to expand total capacity in a single fiber. CWDM provides a flexible network architecture and pay-as-you-go for service providers, enabling increased bandwidth from 2.5Gb/s to 12.5Gb/s downstream and from 1.25Gb/s to 6.25Gb/s upstream. The CWDM GPON transceivers are compliant with the existing GPON ITU standard G.984.2.

“With continuing bandwidth demand to support internet video and 3G wireless network growth, 10G EPON [10 Gigabit Ethernet PON] and XG-PON [10 Gigabit-capable PON] are emerging in the market,” says Darron Young, senior director of Product Line Management. “However, 10G PON technology has not yet reached maturity and a competitive cost point,” he adds. “Our CWDM GPON transceivers are based on the existing mature GPON products, and provide an immediate, alternative solution to allow service providers to expand their bandwidth with minimum investment.”

The CWDM GPON products complement Source Photonics’ existing 10G PON and 10G EPON product portfolio, so the firm now offers all next-generation PON solutions. The new transceivers are sampling now and are expected to be fully released for production in early 2011.
