CATV Optical Transmitter

BC 1550-10dBm-0 INT is an economic solution for transmitting 1550nm in short distance. Comparing with the traditional pre-distortion circuit, it takes advantage of improving non-linear parameters, which enhances stabilities during signal transmitting. BC 1550-10dBm-0 INT operates with 10dBm output power, wide frequency band, high non-linear ratios and low distortion.


Powerful and flexible network construction mode: Between any two PON ports of DBC OLT Series, the
redundancy of the backbone optical fiber is supported and the switchover time is less than or equal to 50ms.
At the same time, DBC OLT series supports to establish RSTP and EAPS between SNIs and the switchover time
is less than or equal to 50ms. Additionally it can work together with industrial DBC ONU Series to construct
the bus or tree network topology with hand-in-hand protection.
 EPON transmission network: The optical fiber is used as the transmission media and there is no source in the
whole transmission, so it runs stably and reliably. The bidirectional high-bandwidth services can be realized
on a single fiber with a downlink/uplink rate of 1.25Gbps. The EPON network supports the multi-level
prismatic bus topology which is suitable to the structure of the power lines of the distribution network.
 QoS guarantee for multi-services: The QoS mechanism, based on ITU-T Y.1291, is supported, including
priority labeling, queue schedule, flow shaping, congestion limit and cache management. Different users and
services have different delays, jitters, guaranteed bandwidths and maximum bandwidths, and the DBA
mechanism is supported so that the uplink bandwidth of each DBC ONU can be distributed and limited.

Various Ethernet functions: Multiple technologies are supported, such as VLAN isolation, port
protection, MAC binding, IP binding, port limit, queue and flow control, so the combination of
multiple services can be developed without technical bottleneck and upgraded smoothly.
 Unified and versatile network management system: The network management system is service
oriented and it provides the unified network transmission and networking protocol, address
management, domain management, security management, user access management and so on. It has
rich OAM functions such as configuration, alarm, performance monitoring, trouble isolation and
security management. At the same time, it supports the CLI/GUI management, which is easy to use.
 Industrial-level design suitable to the electric power industry: DBC OLT Series provides such
interfaces as GE interfaces and FE interfaces. This series of products can be applied in harsh
environments and running in the temperature range between -40°C and 80°C, prevent thunder attacks
and strong electromagnetic interference

Fiber optic adapters, SC/FC/ST/LC/MTRJ/MU/E2000,Single mode,multimode,upc,apc,pc.

Fiber optic adapters is also called mating sleeves,which are used to connect optical connectors of same type, such as FC, SC and ST. optical adapters are widely uses in light distribution frame(ODF), the optical fiber communications equipment, the measuring appliance and so on.

Features of optical adapter:
The optical adapter connects fiber transmission by its placket tube. We offer various shapes of high-performance adapters to ensure maximum connectivity between the fiber jumper. In order to fix a varity of board level, our company designed various sophisticated fixed flange.
