OC-3 Small Form Factor
(SFF) Transceiver
CF2 Series
The JDS Uniphase CF2 Series OC-3 transceiver is
a duplex-LC transceiver designed for use in
SONET OC-3 and SDH STM-1 applications. It
operates with a single 3.3 V power supply. The
unit conforms to the industry-standard 2x5 and
2x10 footprints and meets the mezzanine height
requirement of 9.8 mm.
Each transceiver consists of an optical
subassembly housing both the transmitter and
the receiver, and an electrical subassembly. All
are packaged together with a top metal cover and
bottom shield.
The optical subassembly comprises two parts:
the transmitter side has a high-performance
1300 nm Fabry-Perot (FP) or 1550 nm
distributed feedback (DFB) laser and back facet
monitor. The receiver side has an InGaAs PIN
and a preamplifier.
All CF2 Series OC-3 transceivers also include a
signal detect circuit, which provides either a
Positive Emitter Coupled Logic (PECL) or TTL
logic high output when a usable input optical
signal level is detected.
