Source Photonics launches XGS-PON N2 OLT transceiver

Source Photonics has launched the XGS-PON N2 OLT optical module, which it claims is the first in the market to offer a universal upgrade path from existing GPON networks to next-generation XGS-PON networks.

The new transceiver meets the N2 class maximum optical link budget of 31dB in the XGS-PON standard G.9807.1, thus providing operators with a single module that supports the upgrade of both B+ and C+ class GPON networks to XGS-PON.

Source Photonics will offer the XGS-PON N2 OLT module in the XFP form factor. The module provides symmetric data rates of 9.953Gb/s downstream and upstream, and supports a 1:64 split ratio on 20km links.

“Source Photonics is known to be an innovator in the PON optical transceiver market,” said Albert Hu, senior director of product line management, “The industry’s first XGS-PON N2 OLT optical transceiver once again proves our leadership position and our determination to provide advanced products to our customers."

The new product is the first to be announced after Source Photonics’ was purchased by a private equity consortium led by Redview Capital and Asia-IO. Under its new ownership, Source Photonics is increasing its manufacturing capacity for next-generation optical access products (see Source Photonics invests in next-generation FTTx products).

Source Photonics says its investments have resulted in the development of higher-output power class products, which will facilitate not just network upgrades but also network overlay of GPON and XGS-PON in existing GPON C+ class fibre plants. The company says it needed to enable transmit optical power of greater than 4dBm in order to meet the N2 class link budget requirement.

Continued investments in laser, photodetector, and optical coupling technologies will enable Source “to maintain the most operationally integrated portfolio in the FTTx module industry,” the company adds.

The XGS-PON N2 OLT will begin sampling in March 2017 and will be available for production in the third quarter of 2017. The product will be on display at OFC on 21–23 March, in Los Angeles, booth #3011.
