DESCRIPTION

The Quad Fiber Remote SFP (QDFRS) is a customer premise fiber optic 

access unit. The QDFRS provides four DS1 interfaces that can be multi-

plexed together over single-mode fiber to a Total Access

®

 3000/3010 

Quad Fiber Central Office SFP Module (QDFCS; P/N 1181308L8).
The QDFRS provides a high degree of resistance to damage that is 

typically caused by Ground Potential Rises (GPRs), by optically isolating 

the network interface from the customer side and providing DS1 inter-

faces with over 6 kV of isolation with respect to ground.
The QDFRS operates using ±24 or ±48 VDC, nominal.
The QDFRS uses a Small Form-Factor Pluggable (SFP) to provide the 

optical interface. The SFPs supported are listed in the table below.

Note: All SFPs use LC connectors.

Operation

The QDFRS provides a platform to exchange data between four DSls and 

an optical fiber interface. The customer data connection is through the 

RJ-48C connectors. An optical fiber interface is provided for communi-

cation with the loop. The QDFRS operates with a QDFCS module at the 

other end of the fiber optic cable.
DS1 loop connections are made via four RJ-48C connectors. For each 

connector, transmit tip and ring are on pins 2 and 1, and receive tip and 

ring are on pins 5 and 4, respectively. Connect the single-mode fiber(s) 

to the LC connectors on the QDFRS back panel (requires SFP).
The RJ-48C pin-out configuration is illustrated in the figure below.

INSTALLATION

Inspect the QDFRS. If damaged, file a claim with the carrier and then 

contact ADTRAN. Refer to “Warranty” for more information. 
To install the QDFRS, complete the following steps:

1. Place the QDFRS where ±24 or ±48 VDC power is available.
2. If wallmount installation is required, attach the supplied hangers to 

the QDFRS and mount it accordingly.

3. Insert the desired SFP into the QDFRS rear panel 

 slot.

4. Connect the positive and negative power wires to the positive and 

negative terminals on the rear of the QDFRS.

5. Connect the ground wire to the ground slot of the connector, or to 

the #10 lug on the side of the QDFRS.

6. Connect the optical fiber(s) to the LC connectors on the SFP.

DIAGNOSTICS

The options available for diagnostics include front panel LEDs, loopback 

tests, performance monitoring, and a DS1 test jack. Loopbacks can be 

initiated remotely from the QDFCS or manually from the QDFRS.

LEDs

Pushbuttons

Use the pushbuttons on the QDFRS front panel to initiate bilateral 

loopbacks. Data from the port input is sent to the port output, and data 

from the fiber interface is sent back to the fiber.
