CWDM Fiber Optical Transceiver

CWDM is used in Ethernet and point to point connections,and especially suitable for big bandwidth and short distance data transmission such as between buildings, CWDM offer an economic solution compared with expensive DWDM equipment,people also use CWDM with the PON(passive optical network) to offer multi connection.

The CWDM fiber optical transceivers feature Uncooled MQW DFB LD,1X9 Pin / GBIC / SFF / SFP Package Optional,with Single +3.3V or +5V Power Supply, PECL Data Interface,CWDM fiber transceivers are with 1270~1610nm 18 Wavelength Channel Optional,Operating Temperature range is from 0℃ to +70℃,they are Compliant with Telcordia (Bellcore) GR-468-CORE standard,Eye Safety, Meet Laser Class 1, Compliant with IEC60825-1,RoHS Compliant fiber optical transceivers also available.

The CWDM fiber optical transceivers are with SC or LC fiber connection interface,with data transmission rate from 1.55Mbps,622Mbps,1.25Gbps ,up to 2.5Gbps,the CWDM optical transceivers working wavelength is 1470nm, 1490nm, 1510nm, 1530nm, 1550nm, 1570nm, 1590nm and 1610nm. they are suitable to be used in Gigabit Ethernet ,ATM,SONET/SDH and Fiber Channel etc.

Fiber Optic Transceiver

A fiber optic transceiver is a device used to transmit and receive optical signals in a optical network. Optical transceiver facilitates bi-directional data transmissions between electronic devices (e.g., computer, input/output system, peripheral device, or switch) and optical data links in fiber optic systems. Fiber optic transceivers mainly include GBIC transceivers, SFP transceivers, SFP+ transceivers, XENPAK transceivers, X2 transceivers and XFP transceivers.

GBIC is short form of Gigabit Interface Converter. GBIC transceiver is an interface device used to convert Gigabit electrical signal to optical signal. GBIC is an international standard interchangeable products.

SFP stands for Small Form-factor Pluggable transceiver. SFP transceiver is also named as Mini GBIC, for its function is similar as the GBIC transceiver.

SFP+ is the upgraded from SFP transceiver. SFP+ transceiver is with higher data rate. Xtransceiver supply SFP+ SR and SFP+ LR modules. They are fully inspected according to the industrial standards and are Rohs compliant.

XENPAK transceiver is hot pluggable 70-pin Connector with XAUI Electrical Interface. It is in a 4.8×1.4×0.7 inch package. XENPAK is Compatible with XENPAK MSA Rev3.0 and support of IEEE 802.3ae 10GBASE-LR. XENPAK transceiver is used in 10GBASE-LR 10G Ethernet.

X2 Transceiver is a type of 10 Gigabit Ethernet optical transceiver. X2 transceiver is based on XENPAK transceiver module, and it has same function with XENPAK transceiver. X2 is better for density installation for it is only half size of XENPAK transceiver.

XFP transceiver is a 10 Gigabit Small Form Factor Pluggable optical transceiver. It is protocol independent. It is usually 850nm, 1310nm or 1550nm. XFP transceiver is used for 10Gbps of the SONET/SDH, Fiber Channel, Gigabit Ethernet, 10 gigabit Ethernet and other applications.
