Tx CWDM Rx 1550nm BOSA

: http://laserdiodedevice.com/6-1-tx-cwdm-rx-1550nm-bosa.html

One end of the Tx CWDM Rx 1550nm BOSA is a CWDM laser, which is used to transmit signals, and the other end is an InGaAs detector, which is used to receive signals. The packaging form for this BOSA is a pigtailed package type, which makes it ideal for use in optical communication systems. Length and connector types can be customized according to customer requirements.
