Sumitomo Electric Lightwave (SEL), a Sumitomo Electric Industries Group company, has introduced its FTC7511 10G ONU Concentrator (ONU-C). The fiber-to-the-distribution-point (FTTdp) system, targeted primarily toward cable operators, supports service delivery to clustered developments with per-subscriber provisioning, management, and QoS unavailable in traditional FTTdp designs, SEL asserts.
The FTC7511 combines eight 10G-EPON optical network units (ONUs) in a single 1RU temperature-hardened enclosure. The ONUs share a common transceiver and power source. The design offers significant optical budget and power savings versus the use of eight standalone ONUs, SEL says. For customer-side connectivity, the 10G ONU-C offers an RJ-45 or SFP cage user network interface (UNI) to each subscriber.
SEL says the FTC7511 enables cable operators to overcome such common FTTx deployment challenges as limited trunk fiber, need for longer distances, management of deployed equipment, and a geographically concentrated or dispersed customer base. In addition to power savings, the 10G ONU-C can overcome these challenges through support of:
- Increased transmission distance (up to 40 km) via the optical budget savings
- Support of more subscribers per optical distribution network (ODN)
- Access equipment and CPE independence
- Simpler installation and operator maintenance
- CPE plug-and-play capabilities.
