DESCRIPTION

The SPB-4940RLWG is a 1 to 6.25 Gb/s single-mode

transceiver module for serial optical communication

applications for a radio base station system by using 1330

nm transmitter and 1270 nm receiver. It is with the SFP

20-pin connector to allow hot plug capability. Digital

diagnostic functions are available via an I

specified in the SFP MSA SFF-8472.

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.

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.
