1.25Gbps Symmetric EPON Transmission
The BDCOM P1501DT supports symmetric 1.25Gbps PON transmission in both upstream and downstream directions. This provides a high-capacity optical connection between the subscriber ONU and the EPON OLT.
The actual user-access throughput depends on the OLT configuration, optical split ratio, service profile, network congestion, Ethernet interface, and ISP bandwidth allocation.
Gigabit Ethernet Interface
The P1501DT provides one Gigabit Ethernet interface for connecting subscriber-side equipment such as routers, switches, computers, Wi-Fi access points, or other Ethernet devices.
The Gigabit Ethernet interface provides a practical connection between the optical access network and the customer's local Ethernet network.
SC/UPC EPON Optical Interface
The P1501DT uses an SC/UPC EPON optical interface for connection to the passive optical fiber distribution network.
The optical connector and fiber infrastructure should be matched correctly during installation. Fiber connectors should also be kept clean and protected from dust to maintain reliable optical performance.
1:64 Optical Splitting
When connected to compatible BDCOM OLT equipment, the P1501DT series can support a 1:64 splitting ratio. This allows a single PON port to serve multiple subscriber connections through a passive optical splitter.
The actual supported split ratio depends on the OLT, optical power budget, splitter losses, fiber distance, connectors, splices, and overall network design.
20km Network Coverage
BDCOM's P1501DT documentation specifies a network coverage radius of up to 20km. This figure represents the specified optical network capability and should not be interpreted as a guaranteed distance for every installation.
Actual deployment distance depends on the complete optical link budget and the losses introduced by fiber, splitters, connectors, splices, and other passive components.
VLAN and Network Security
The P1501DT includes several Layer 2 networking and security functions designed for service-provider environments. Supported features include VLAN, STP, ACL, security filtering, and broadcast storm control.
These features can help network administrators isolate traffic, control subscriber services, and improve the stability and security of EPON access networks.
QoS and Bandwidth Control
The ONU supports Quality of Service (QoS), Dynamic Bandwidth Allocation (DBA), and rate limiting. These functions allow service providers to control subscriber bandwidth and prioritize traffic according to the configured service profile.
The P1501DT supports dynamic bandwidth distribution and bandwidth limitation, helping operators allocate available PON capacity according to subscriber and service requirements.
OAM and Management Functions
The P1501DT series supports standard and expanded OAM functions, including configuration, alarm handling, performance monitoring, fault isolation, and security management. It also supports BDCOM private OAM functions.
This management capability allows the ONU to be integrated into professional EPON service-provider networks where centralized device administration is required.
Applications

- Fiber-to-the-Building (FTTB)
- ISP broadband networks
- EPON subscriber access
- Residential fiber Internet
- Small business fiber connectivity
- Enterprise fiber networks
- Fiber-based CCTV networks
- Multi-service access networks
- Telecommunications infrastructure
EPON Network Architecture
The P1501DT operates as the subscriber-side ONU in an EPON network. Its optical port connects to the fiber distribution network and ultimately to an EPON OLT.
In a typical deployment, an optical splitter distributes the PON signal from the OLT to multiple subscriber ONUs. The P1501DT then converts the optical connection into Gigabit Ethernet for the customer's local network.
Compact Subscriber-Side Design
The P1501DT is designed as a compact single-port ONU with a plastic housing. Its small form factor makes it suitable for residential installations, small businesses, network cabinets, and other subscriber locations where a compact fiber termination device is required.
The product uses an external power adapter, helping keep the ONU compact and easy to install near the customer's network equipment.
Compatibility Notice
The BDCOM P1501DT is an EPON ONU, not a GPON ONU. It should be deployed with compatible EPON OLT infrastructure.
BDCOM documentation states that the P1501DT series can work with OLTs from mainstream manufacturers, but actual interoperability depends on the OLT, firmware, OAM implementation, VLAN configuration, authentication method, and service profile.
Why Choose the BDCOM P1501DT?
The BDCOM P1501DT combines Gigabit Ethernet connectivity, 1.25Gbps symmetric EPON transmission, 1:64 split support with compatible BDCOM OLTs, 20km specified coverage, and advanced VLAN, QoS, DBA, and security functions.
It is a practical subscriber-side ONU for ISP and professional fiber-access deployments that require Gigabit Ethernet connectivity over an EPON network.
