HUAWEI 0231A11V is Tx1490nm/Rx1310nm wavelength, Duplex HUAWEI optical transceiver,through LC connector,transmitting distance can reach up to 10km .

Cozlink provide CZT-W431G-10D (in stock) compatible optical transceiver using DFBlaser,Sold in eBay and amazon,we have fully stocked,high production efficiency and fast delivery time.

All of Cozlink products are 100% tested , and can be completely applied in Ethernet、Fibre Channel network devices, such as switches and routers.

If you want to get latest product datasheet or don’t know how to buy it, please feel free to contact our service online.

(Note:Class 1 laser output power is less than 0.4mW,it won’t be harmful to eyes,we can ensure the safe in design.)(with DDM function can help system management to predict the life of optical transceivers, isolate system faults and verify the modules compatibility in the site installation.

The CZT-W431G-10D CSFP 1000BASE-BX LC 2-Channel bidirectional transceiver is intended for 10km reach service in 1250Mb/s single mode high-speed LAN and SAN data communications equipment where low-cost, extraordinary performance and reliability are essential. It meets the requirements of IEEE802.3ah 1000BASE-BX, consumes low power, operates from a 3.3V DC power supply and is offered in the commercial and industrial temperature ranges. The industry standard 2x10 compact small form pluggable (CSFP) package is fabricated with a rugged die cast metal housing and cage assembly. The low jitter and low bit error rate optical assembly features a 1490nm DFB laser transmitter and 1310nm PIN/TIA receiver. It incorporates the CSFP MSA LVTTL Loss of Signal (Rx_LOS), Tx Fault (Tx_FAULT) and Tx Disable (Tx_DIS) monitor and control functions and the SFF-8472 Rev9.5 compliant digital diagnostic monitor feature which is accessed via the I2C 2-wire serial ID interface. The device is Class I laser safety compliant.
