FEATURES
DESCRIPTION
l 1-Fiber Bi-Directional SFP Optical Transceiver
l CPRI / OBSAI Compatible Optical Interface
l 1 G to 6.25 G Multi-rate Specification
l Compliant with SFP+ MSA
The SPB-4840RLWG 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 1270
nm transmitter and 1330 nm receiver. It is with the SFP
20-pin connector to allow hot plug capability. Digital
diagnostic functions are available via an I2C series bus
specified in the SFP MSA SFF-8472. The transmitter
section uses a multiple quantum well 1270 nm DFB laser
and is a class 1 laser compliant according to International
Safety Standard IEC 60825. The receiver section uses an
integrated 1330 nm detector preamplifier (IDP) mounted in
an optical header and a limiting post-amplifier IC.
