HD multimedia surveillance often requires long-distance uncompressed digital audio/video transmission. Ordinary cables suffer poor output, interference and limited reach. The 3G/HD-SDI-T/R optical pair carries 3G/HD-SDI over 1m–20km, addressing these problems. Low attenuation, broad bandwidth, interference resistance, security, compactness and light weight suit long distances/special environments while reducing construction cost and wiring complexity without sacrificing quality. 3G/HD-SDI-T is the transmitter and 3G/HD-SDI-R the receiver. The source also labels the transmitter 3G/HD-SDII-T. Together they send video over fiber without compression and faithfully reproduce the original signal.

Product Function Description: Fiber Transmission of4 E1+30 Telephone Channels(Optional Magneto/Hotline Telephone,2/4-Wire Audio,Data,etc.)+4 Fast Ethernet Channels;1U Rack Equipment;RJ45 Telephone Interfaces(1 Channel per Port,Pin Assignment4/5) Service Port Description: 1 Optical Interface(155M,Optional Single/Dual-Fiber Transmission,FC or SC);4 E1 Interfaces(BNC);30 Telephone Interfaces(RJ45);4 Fast Ethernet Channels(Shared or Logically Isolated) Power Supply: AC-220V or DC48V Single Supply, Optional Dual AC220V/DC48V Supplies

The integrated service-access device provides 30 telephone channels, 4E1 and four 100M Ethernet channels. Proprietary large-scale integrated circuits use time-division multiplexing to encode Ethernet and E1 signals together for transmission over a fiber pair. Mixed services include 100M Ethernet, E1, voice, V35, data and two-/four-wire services, through optical or E1 transmission channels. A highly integrated 19-inch 1U chassis offers small size, low power, reliable operation and easy installation and use.

Ringing Voltage [FXS Subscriber Telephone Port / Orderwire Telephone Port]: 75 V Ringing Frequency [FXS Subscriber Telephone Port / Orderwire Telephone Port]: 25 Hz Two-Wire Input Impedance [FXS Subscriber Telephone Port / Orderwire Telephone Port]: 600Ω (Off-Hook)

This telephone-to-Ethernet optical terminal encapsulates voice in IP packets using UDP. The description states conversion of 1–8 voice services to two 100M Ethernet channels, labeled one RJ45 optical port and one 100M Ethernet optical connection, for communication within one subnet or across routed subnets. A separate port list gives eight RJ11 telephone ports, one 10/100/1000M adaptive Gigabit RJ45 Ethernet port and one FC/UPC optical port, single-mode, single-fiber bidirectional, 80KM. Power is external.

Maximum Capacity per Chassis: Dual-Fiber Bidirectional 8X200G / 4X400G, 1.6Tbps Line-Side Modulation Mode: DP-QPSK@100G DP-16QAM@200G; DP-8QAM@200G; DP-QPSK@200G DP-16QAM@400G Line-Side Protocol: SD-FEC/OpenROADM/OpenZR+

FW-8800 is a compact 1U 400G DCI BOX, described as 1.6T fully populated, converting four 100G QSFP28 channels to 400G CFP2. Four 400G boards provide a stated bidirectional 3.2T service capacity. Dual-fiber point-to-point DWDM supports 48×400G at 100GHz or 64×400G at 75GHz. Independently developed by 广州市瑞东Email 科技有限公司 for 400G transmission, each board converts four 100G clients to one 400G line for multiservice, high-capacity networks. A 1U chassis holds four boards for up to 3.2Tbps service capacity. Uses include data-center DCI, metro access and aggregation, with intelligent optical-transport solutions across capacities/distances.
