1.25Gbps CWDM (Coarse Wavelength Division Multiplexing) GBIC transceivers are designed to operate over two fiber multi-mode or single mode optical cables with distance 40km and 80km. These optical modules supports Gigabit Ethernet (1.25 Gbps) and 1G-FC Fiber Channel (1.063 Gbps) applications. Each transceiver uses one 20nm wide CWDM channel according ITU-T G.694.2 CWDM grid for transmission, but can receive all CWDM range wavelengths (1470 – 1610 nm).

The GBIC transceiver is high performance, cost effective module supporting dual data-rate of 1.25Gbps/1.0625Gbps and from 80km transmission distance with SMF. 

The transceiver consists of two sections: The transmitter section incorporates a DFB laser. And the receiver section consists of a PIN photodiode integrated with a trans-impedance preamplifier (TIA). All odules satisfy class I laser safety requirements. 

The optical output can be disabled by a TTL logic high-level input of Tx Disable. Tx Fault is provided to indicate degradation of the laser. Loss of signal (LOS) output is provided to indicate the loss of an input optical signal of receiver. 

The standard serial ID information Compatible with GBIC MSA describes the transceiver’s capabilities, standard interfaces, manufacturer and other information. The host equipment can access this information via the two-wire serial CMOS EEPROM protocol. For further information, please refer to SFF-8053.

The Cisco 1000BASE-CWDM GBIC 1470 nm is guaranteed 100% Compatible and Functional in its intended equipments. Every CWDM-GBIC-1470 is environmentally tested in its specific port/platform prior to shipping to ensure that they are in perfect physical and working condition.

Cozlink also supply CWDM mini GBIC,which is called cwdm sfp transceiver.And CWDM-SFP-10G-1470 is 10G sfp+ CWDM 1470nm 40km modules. About DWDM Gbic modules,at present,we are still studying it.If you need,you can see cisco cwdm sfp compatibility matrix on the Internet.

Besides,we can also supply high speed cables ,media converters and other passive fiber optical products.
