Description

2×5 SFF GE-PON PX20 ONU transceiver family is

Optical Network Unit (ONU) for IEEE802.3ah™-2004

1000BASE-PX20-U application

The transceiver is the high performance module for

1.25Gbps data link in single fiber by using 1310nm

burst-mode transmitter and 1490nm continuous-mode

receiver with 1550nm optical signal rejection.

The transmitter section uses a multiple quantum well

1310nm DFB laser and is Class Ⅰ laser compliant

product according to international safety standard

IEC-60825. The receiver section uses an integrated

1490nm PIN and preamplifier mounted in an optical

header and limiting post-amplifier IC.

The optical burst output can be enabled by a LVTTL

logic high-level input of TX_BRST. Signal Detected (SD)

output is provided to indicate the detection of an input

optical signal of receiver.
