Gigabit EPON Connectivity
The BDCOM P1501 D1 is designed for Gigabit EPON access networks. Its PON interface supports symmetric 1Gbps transmission, allowing compatible subscriber networks to receive high-speed fiber connectivity.
The unit connects to an EPON OLT through the optical distribution network. At the customer side, its Gigabit Ethernet RJ45 port provides the connection to a router, computer, switch, Wi-Fi access point, or other compatible Ethernet equipment.
1 × Gigabit Ethernet Port
The P1501 D1 provides one 10/100/1000Mbps auto-adaptive RJ45 Ethernet interface. The port automatically negotiates the appropriate Ethernet speed with the connected device.
This single-port configuration is suitable for subscriber installations where the ONU is connected directly to a router or another Ethernet device.
SC/PC EPON Optical Interface
The ONU uses an SC/PC optical interface for its EPON connection. The optical interface connects the device to the passive optical distribution network and ultimately to the service provider's EPON OLT.
Fiber connectors should be kept clean and protected from dust during installation. The optical fiber and connector type should also match the requirements of the installed EPON infrastructure.
EPON Standard Support
The P1501 D1 complies with IEEE 802.3ah EPON and related EPON requirements. The P1501D1 series documentation also identifies support for IEEE 802.1D Spanning Tree, IEEE 802.1Q VLAN, IEEE 802.1w RSTP, and ITU-T Y.1291.
These standards allow the ONU to integrate into professional Ethernet and EPON access-network environments.
VLAN and Network Management Features
The P1501 D1 supports network functions designed to help service providers and administrators manage subscriber traffic. VLAN capabilities include port-based VLAN and IEEE 802.1Q VLAN.
The series also supports features including QoS, flow control, multicast handling, and network security functions. Exact management capabilities can depend on the deployed firmware and OLT environment.
QoS and Traffic Control
The P1501 D1 supports quality-of-service functions for prioritizing network traffic. The available specifications identify multiple transmission queues and IEEE 802.1p-based priority handling.
Flow-control features help manage traffic between the optical network and Ethernet interface, which can be useful in broadband and multi-service access deployments.
Multicast Support
The P1501D1 series supports IGMP Snooping and MLD Snooping, along with CTC-defined dynamic multicast functions. These capabilities can help manage multicast traffic in compatible EPON networks.
Multicast management is particularly useful for service-provider deployments that carry IPTV and other multicast-based services.
Applications
- Fiber-to-the-Home (FTTH)
- Fiber-to-the-Building (FTTB)
- EPON broadband networks
- ISP subscriber connections
- Residential fiber Internet
- Small business fiber connectivity
- Enterprise fiber access
- Fiber-based CCTV infrastructure
- Multi-service access networks
- EPON subscriber deployments
EPON Network Architecture
In a typical deployment, the BDCOM P1501 D1 operates as the subscriber-side ONU. The device connects through its SC/PC EPON interface to an optical splitter and fiber distribution network, which ultimately connects to an EPON OLT.
The Gigabit RJ45 interface then provides Ethernet connectivity to the customer's local network. This architecture allows an ISP or network operator to deliver fiber-based broadband services to the subscriber location.
Optical Performance
BDCOM's P1501D1 series documentation specifies a network coverage diameter of up to 20km, optical receiver sensitivity of ≤ -27dBm, and transmit power of 0-4dBm.
Actual fiber distance depends on the optical budget, splitter configuration, fiber quality, connectors, splices, and other components in the complete optical path.
Compatibility Notice
The P1501 D1 is an EPON ONU, not a GPON ONU. It should be deployed with a compatible EPON OLT and optical distribution system.
Although the P1501D1 series documentation indicates interoperability with OLTs from mainstream manufacturers, actual interoperability should be verified with the specific OLT, firmware, authentication method, VLAN configuration, and service profile before deployment.
Why Choose the BDCOM P1501 D1?
The BDCOM P1501 D1 provides a straightforward Gigabit subscriber-side EPON solution with one optical interface and one Gigabit Ethernet port. Its support for VLAN, QoS, multicast, flow control, and ONU authentication makes it suitable for professional broadband access networks.
Its compact single-port architecture is particularly appropriate for FTTH and small subscriber deployments where a multi-port ONU is unnecessary.
