10G Multimode 300m DDM | Dual Fiber SFP+ Transceiver


SKU: UC-SFP10GSR-3903D Category:


UconX®3903D is a Cisco® SFP-10G-SR compatible fiber transceiver module that has been designed, programmed and tested to work with Cisco® brand switches and routers. It is a very compact 10Gb/s optical transceiver module for serial optical communication applications at 10Gb/s. The JHA3903D converts a 10Gb/s serial electrical data stream to 10Gb/s optical output signal and a 10Gb/s optical input signal to 10Gb/s serial electrical data streams. The high speed 10Gb/s electrical interface is fully compliant with SFI specification. The high performance 850nm VCSEL transmitter and high sensitivity PIN receiver provide superior performance for Ethernet applications at up to 300m links. The SFP+ Module compliants with SFF-8431, SFF-8432 and IEEE 802.3ae 10GBASE-SR. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-8472. The fully SFP compliant form factor provides hot pluggability, easy optical port upgrades and low EMI emission.
