Description
Description
◆ This BOSA is a high performance optical sub-assembly in single fiber by using 1310nm transmitter and 1490nm receiver.
◆ The transmitter section uses a multiple quantum well 1310nm DFB laser supporting burst-mode operation. The receiver section uses an integrated1490nmAPD and preamplifier mounted in a TO-can.
Features
◆ Laser welded package
◆ Single fiber pigtail type Bi-directional play designed for full-duplex digital communication
◆ Asymmetric 2.5Gbps downstream and 1.25Gbps upstream data link transmission
◆ Integrated micro-optics WDM filters for dual wavelength Tx/Rx operation at 1310/1490nm
◆ 1310nmlnGaAsP/InP MQWDFB laser diodetransmission with InGaAs monitor photodiode
◆ 1490nm APD diode digital receiver with integrated 10Gbps,3.3V continuous mode pre-amplifer
◆ High optical isolation from external source and low optical cross-talk from intemal source
◆ -5℃ to 75°C commercial operating temperaturerange with excellent temperature dependent power tracking ratio
Standard
◆ Compliant with Telcordia GR-468reliability test criterion
◆ Compliant with RoHS6 standard
◆ Compliant with GR-326 connector qualification standard
Applications
◆ GPON Bi-directional play transceiver,ONU
◆ FTTH Bi-directional play
◆ GPON ONU ITU-T G984.2Class B+ compliant
