BroadLight is a fabless semiconductor company supporting the Fiber to the Premise (FTTP) market with optical transceivers, digital PON controllers (MAC) for both
Central Office (CO) and Customer Premises Equipment (CPE), and software stacks. BroadLight offers a complete PON solution at the components level, which will enable
system vendors to shorten time to market for emerging last mile networks.
BroadLight is an Israeli start-up company, founded in July 2000, to develop a unique offering to system vendors enabling them to come out with PON systems easily
and with a short time to market. The company has recently achieved a number of important design wins from leading system vendors that are using the complete offering for their PON
solution.
The company is committed to work closely with vendors and carriers to support them throughout the project planning and integration process.

BroadLight's line of optical transceivers products includes Bi-Directional and Three Wavelength Burstmode Transceivers along with CATV receivers.
BroadLight's transceivers support upstream and downstream bandwidth with flexible data rates for both the CPE and Central Office.
The BBT-N and BBT-L are a family of Bi-Directional Burst-mode Optical PON Transceivers for ONU/ONT and OLT transceivers. The BBT-N and BBT-L product lines comply with ITU-T
G.983.x (FSAN). These products incorporate BroadLight leadership in burst mode technology and are protected by several patents.
The BTT-N is single fiber three wavelengths PON transceiver, with embedded Analog Video Receiver. The BTT-N family is designed for FTTP applications to enable full 'Triple
Play' service offerings. The new BTT-N family takes the functionality of the BBT-N family and integrates an additional video receiver over a separate wavelength on the ONU
side. The BTT-N complies with ITU-T G.983.3.
The GE-PON transceivers distinguish themselves amongst other SFF, MSA and IEEE 802.3ah compliant devices with its guaranteed optical performance. The OLT transceiver has a
receive sensitivity of -30dBm and a +2dBm minimum launch power. The ONT transceiver offers a -27dBm receive sensitivity and a 0dBm launch power. The 3 wavelength, GE-PON ONT
triplex transceiver operates over ITU-T compliant wavelengths and provides the same performance as the SFF device for data while delivering exceptional CATV quality from a
receive sensitivity of +2 to ?6dBm on the 1550 nm broadcast video wavelength
