LASER SAFETY

This single-mode transceiver is a Class 1 laser product. It

complies with IEC-60825 and FDA 21 CFR 1040.10 and

1040.11.

The transceiver must be operated within the

specified temperature and voltage limits. The optical ports

of the module shall be terminated with an optical connector

or with a dust plug.

DESCRIPTION

XPB-4910LWG series transceiver is single mode

transceiver is for bi-directional serial optical data

communications such as 8x/4x/2x FC-BX by using 1330 nm

transmitter and 1270 nm receiver..

The transceiver consists of two sections: The transmitter

section uses a multiple quantum well 1330 nm DFB laser

and is a class 1 laser compliant according to International

Safety Standard IEC 60825. The receiver section uses an

integrated 1270 nm detector preamplifier (IDP) mounted in

an optical header and a limiting post-amplifier IC.

The module is with the XFP 30-pin connector to allow

hot plug capability. Integrated Tx and Rx signal conditioners

provide high jitter-tolerance for full XFI compliance and no

external reference clock required. The internally ac coupled

high speed serial I/O simplifies interfacing to external

circuitry. Only single 3.3V power supply is needed. The

optical output can be disabled by LVTTL logic high-level

input of TX_DIS. Loss of signal (RX_LOS) output is

provided to indicate the loss of an input optical signal of

receiver.

A serial EEPROM in the transceiver allows the user to

access transceiver digital diagnostic monitoring and

configuration data via the 2-wire XFP Management

Interface. This interface uses a single address, A0h, with a

memory map divided into a lower and upper area. Basic

digital diagnostic data is held in the lower area while specific

data is held in a series of tables in the high memory area.
