3.3.6 Optical Connections

Optical connections between the Host SeRF card and the Remote are supported

through Small Form-Factor Pluggable (SFP) transceivers. The optical interfaces are

standard single-mode duplex LC (flat polished UPC). One SFP comes with the

Host—additional SFPs (up to 7) must be ordered separately as needed.

There are two fiber connections—one FWD and one REV—for each SFP. As the SeRF

holds up to eight SFPs, there is a total of 16 connections: eight FWD and eight REV.

The FWD path is 1550nm (from the Host to the Remote) and the REV path is 1310nm

(from the Remote to the Host).

Each FWD port provides an optical connection for the forward path (downlink) signal.

Each REV port provide an optical connection for the reverse path (uplink) signal. Each

REV port can also provide the optical connection for the diversity reverse path

(uplink) signal.

The optical connections are dependent on whether or not a WDM Host module

(accessory) is installed:

•• If the installation does not include a WDM module, proceed to Section 2.9.2 for

the optical connections procedure.

•• If the installation includes a WDM module, proceed to Section 2.10 for the optical

connections procedure.

This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiation can

seriously damage

the retina of the eye. Do not look into the ends of any optical fiber. Do

not look directly into the

optical transmitter of any unit or exposure to laser radiation

may result. An optical power meter sh

ould be used to verify active fibers. A protective

cap or hood MUST be immediately placed over any ra

diating transmitter or optical fiber

connector to avoid the potential of dangerous amounts of radiati

on exposure. This

practice also prevents dirt particles from entering the connector.
