Adtran SFP (mini-GBIC) 1490nm TX/1310nm RX, LC 1442120G1 Folheto

The Small Form-Factor Pluggable (SFP) Gigabit 
Ethernet, Single-Fiber is a bidirectional SFP that 
installs into the Optical Loop Termination (OLT) 
designed to accept SFPs. The SFP provides a single 
optical interface to the GigE physical interface. 
Installed into an appropriate OLT, the SFP provides a 
Gigabit Ethernet interface to the supporting system.

NOTE

To ensure compatibility, refer to the documentation
provided with the OLT.

In a deployment consisting of an OLT with a
1442120G1 SFP installed; the Optical Network Unit
(ONU) should have a complementary 1442120G2 SFP
installed.

The following features are supported on the SFP:

♦

1000Base-LX 1490 nm Transmitter

♦

1000Base-LX 1310 nm Receiver

♦

Optical distance: 20 km maximum

Due to compliance certification requirements, only
SFPs supplied by ADTRAN should be used. ADTRAN
cannot certify system integrity with other SFPs.

Prior to installation, inspect the SFP. If damage has 
occured during shipping, file a claim with the carrier, 
and then contact ADTRAN Customer Support. For 
more information, refer to “Warranty”.
To install the SFP into an appropriate module, 
complete the following steps:

1. Insert the SFP into the SFP cage on the circuit 

board of the host module with the latch handle 
facing outward. Slide the SFP all the way into the 
cage.

NOTE

The latch on the SFP is for removal only. When
removing the SFP, rotate the latch away from the
SFP, the SFP should slide easily out of the cage.

2. Exert adequate pressure to ensure the SFP is 

completely seated in the SFP cage.

3. Do not remove the connector plug until the 

optical fiber connection is made.

It is recommended that the connector plug remain on
whenever the transciever optical fiber connector is
not inserted.

4. Continue the installation and turn-up of the host 

module using the instructions in the Job Aid 
provided with the module, or using the 
Installation and Maintenance Practice (I&M) 
available online at
